Birdy the Mighty



Tsutomu Senkawa was an ordinary kid living in Tokyo. Birdy Cephon Altirra/Altera/Altaria was a beautiful Space Federation law enforcement officer on a mission to stop a plot by alien criminals that involved Earth. One night, during a battle with the alien fugitive Geega, "Berserker Killer" Birdy accidentally attacks Tsutomu, fatally injuring him. To save his life, Birdy has to merge with him. Now, as Tsutomu gets used to sharing a body with a girl, they both have to work together for Birdy to complete her mission.

Called Tetsuwan Birdy in Japan, it's based on a manga that was started and unfinished in the 1980s by Yuuki Masami. The animation studio Madhouse made a four-part OVA series in the 1990s that finished part of the plot, but still left loose ends. In 2003, Masami went on to do a reboot, starting the story over from the beginning. The series ended after twenty volumes, and a new series after a time skip called Tetsuwan Birdy: Evolution is currently running. In 2008, a TV series, Tetsuwan Birdy Decode (Birdy the Mighty Decode) premiered, and in January 2009, the second season, Tetsuwan Birdy Decode 02 (Birdy the Mighty Decode 02), premiered.

Decode can be found on Funimation's Youtube channel here!


 * Accidental Pervert: Tsutomu's dad tries to do bond with his son in the bathtub with his son, but finds a naked Birdy in his place.
 * Action Girl: Birdy
 * Adorkable: Tsutomu in the OVA series.
 * Aliens Speaking English: Played with interestingly in this. If examined carefully enough, you see that in every interaction where there is a potential language problem (i.e. a human and an alien), there can be a reasonable expectation that that alien learned Japanese. For example, Birdy was on Earth for 6 months, working in the modeling business. Aliens that wouldn't know Japanese naturally only speak to other aliens (though of course the dialogue is translated for the viewer), so they are speaking their language. Tsutomu can only understand the aliens because his mind is inside Birdy.
 * Alternate Continuity: The Decode series
 * Also, the OVA and original manga follow a very similar continuity, while the remake manga follows a similar but different continuity.
 * Art Shift: The animation in the second half of the OVA was more cartoony. Also the animation in the seventh and twelfth episodes of the second season of Decode is looser and sketchier than the rest of the series, but expresses extreme momentum and force in the scenes where it is used.
 * Bathtub Bonding: As noted above, Tsuotmu's dad tried to do this with his son, but ended up discovering Birdy.
 * Batman in My Basement: In the OVA, Tsutomu has to keep his situation hidden from his family. This ended-up making his family think he's crazy as he seems to be yelling to himself, his father (in an attempt at Bathtub Bonding with his son) catching a nude Birdy in the bath after she switched with him, his family to wonder why the son is running around the house in the nude, and his sister accuses him of crossdressing when Birdy decides to "borrow" some of her clothes. Averted in Decode, where the sister has moved out and only checks in on him, and his parents have left due to the father's job, leaving Tsutomu alone. The trope remains in the remake manga, though Birdy has her own clothes for being a little less conspicuous.
 * The Berserker: Birdy, to the point that she's earned the nickname "Berserker Killer Birdy."...though, it bears mentioning, the machine she killed in revenge for Violin's death was known as a Berserker.
 * It also bears mentioning that in the remake manga and its currently-running sequel, she goes berserk when pushed enough.
 * Berserker Tears:.
 * Big Bad: Christella Revi, though more hand-ons in the OVA, but her Decode self is also the Big Bad, but is more of a She Who Must Not be Seen/The Voice/Woman Behind the Man.
 * Big Eater: Birdy is one.
 * Biological Mashup/Fusion Dance/Gender Bender/Sharing a Body/They Fight Crime: Series Premise.
 * First Law of Gender Bending: Tsutomu gains his body back in the first season finale of Decode only for it to be destroyed again and he's forced back into Birdy.
 * Shapeshifter Mode Lock: Temporarily. See the "Freaky Friday Flip/Man, I Feel Like A Woman" example.
 * A longer but still temporary mode lock also exists in the remake manga. During the time-jump after the first series, Birdy's consciousness is put to 'sleep' for a couple of years, which happens to let Tsutomu finish high school and start into college as a 'normal' boy.
 * Bio Punk: The society from which Birdy comes has advanced organic technology (for example, their spaceships and some buildings being biological). Their medicine can fix people blown in half, and replace limbs and faces. Beyond that,.
 * Bittersweet Ending: The first season of Decode.
 * The end of episode 11 of season 2 hints at possibly bringing back some of her memories/romance, as she returns for a visit, and asks Hayamiya about all these pictures of her with Tsutomu (back in season 1), and wondering what they're doing there...
 * Bloodier and Gorier/Darker and Edgier: Decode, especially season 2.
 * Body Horror
 * Geega's transformation into his true form in the OVA involves his real face popping from his neck and part of his real neck inflating before firing a blast.
 * Bacillus is an oozing parasite that bonds and kills the host, then moves on to another.
 * In the OVA, a scientist tries to recreate an old super-soldier project he involved in. His experiments ending up mutating the test subjects into monsters.
 * In the remake manga, the same scientist's experiments causes his test subjects to mutate into powerful beasts, with strong animal instincts and urges to go with it.
 * Breather Episode: Episode 8 of Season 2, which focuses mostly on Shouko. At least until the very end of the episode...
 * Brother-Sister Incest: Questionable as we don't know how DNA is selected, but seeing as.
 * Butt Monkey: Tsuotmu, thanks to some of Birdy's antics.
 * Camera Abuse: Early in the first season, Birdy kicks a piece of debris at the non-In-Universe Camera, which nevertheless tumbles backward and cuts out with static.
 * Clingy Jealous Girl: Shouko in Decode 02.
 * Combat Stilettos: Justified in that Birdy uses her heels as kick-off propulsion devices/mini-rockets, though only the remake manga and Decode versions of Birdy has them.
 * And they make such a cool sound, so who can blame the designers?
 * Combat Tentacles: Bacillus uses these in fighting Birdy
 * Cross Dresser: Birdy (in the OVA) would sometimes shift into her form, but still wear Tsutomu's clothes.
 * She does it a few times in the remade manga, too, despite being bigger than him.
 * She also did the same thing in the original manga.
 * Conspicuous CG: Some of the alien vehicles in Decode. Though it's far from jarring and does blend much better than other shows.
 * Dark and Troubled Past/Harmful to Minors: Birdy's past,.
 * Dating Catwoman: In the second season of Decode, Birdy meets up with Nataru, an old friend of hers at the same time as she's assigned to track down some escaped criminals involved in the events of the first season and over the course of the second season, develops feelings for him. At the same time, someone's been killing the escapees.
 * Deadly Nosebleed: Nataru sports one when weakened by his time jumping capability.
 * Does This Remind You of Anything?: The basic premise is remarkably similar to a long-running arc in Marvel's Captain Marvel series, where an ordinary guy must share his body with a powerful superhero who has his own identity and motivations, right down to the two being able to talk to each other.
 * Doing It for the Art: Decode was commercially unsuccessful, but still produced a second season of excellent quality. Sadly, it looks like the series will have another cliffhanger ending.
 * The Dragon: Gomez. In the manga, there are also the four elemental robots -- Undine, Salamander, Sylph, and Gnome.
 * Or maybe not Gomez. At the end of the OVA, . His role is also muddled in the remade manga, since he.
 * Dramatic Chase Opening: The OVA.
 * Earth Is the Center of the Universe: Completely averted. Earth is considered an insignificant backwater planet in the Decode universe.
 * Eyelid-Pull Taunt: In the original manga, Geega does this to mock Birdy after she accidently kills Tsutomu.
 * Hair Decorations: In the original manga and OVA, Birdy sports a hairband with triangular clips around her ears. In the remake manga and Decode, she sports a headset with two fin-like protrusions, each also around her ears.
 * Evil Minions/Robots/Mecha-Mooks
 * Fair Cop: Birdy
 * Fan Service: Though more low-key and tasteful (especially Decode, like all A-1 productions) when compared to other series, it does exist.
 * Toplessness From the Back: Especially in the remake manga where in one scene a doctor lampshades this by touching her rump.
 * Barbie Doll Anatomy: Birdy in the first part of the OVA, somewhat justified in one case by Out-of-Clothes Experience. Subverted in the second part near in the end when the only view of her front is from the shoulders up. Averted in the last two parts as she's not in a situtation where she's nude.
 * Bath Kick: Birdy does this in the first episode of the second season of Decode.
 * Between My Legs: Gets used in the first episode of Decode.
 * Dirty Harriet: In one episode of Decode, Birdy poses as a prostitute at a bar for a short while.
 * Furo Scene: One scene in the OVA and frequent use in Decode. Birdy also loves baths in the manga, since it's much more relaxing than the adjustment tub on her ship.
 * Full-Frontal Assault: A heroic version. As opposed to the OVA, Birdy in the original manga did not don her uniform when Bacillus was outside of Tsutomu's house and confronted him in the nude.
 * Funbag Airbag: When Geega threw Tsutomu at Birdy in the original manga, Tsuotmu ends up slamming into Birdy and his face end up slamming into her chest.
 * Impossibly Low Neckline: Birdy's outfit sports this.
 * Leotard of Power: Birdy's outfit.
 * Sensual Spandex: Birdy's outfit. Basically if there's fanservice, Birdy's usually the subject. However, given that Birdy's outfit is a standard design (even male officers, and non-humanoids like Meguis wear simililar, form-fitting attire) to allow for freedom of movement, it can be seen as practical as Birdy is prone to use speed and feats of acrobatics. With this in mind, another, more "modest" uniform would be cumbersome. Think of it as body armour surrounded by a force field. Furthermore, it is seldom sexualized or used for fanservice shots in the anime or manga. Also, in the remade manga, Birdy has a few other outfits, such as a less-revealing swimsuit-like one piece for down time, and a large triangular poncho for official communications and reports.
 * Sexy Backless Outfit: Birdy, especially in Decode.
 * Fashionable Asymmetry: In the OVA, the boot of Birdy's right leg only comes up to her knee while the one on the left stops at her thigh.
 * First-Episode Resurrection: Tsutomu, though depending on which version you watch, how far into the first episode he dies varies; in the OVA, he dies within the first few minutes while in Decode, he dies after the episode is halfway through.
 * Fantastic Racism: In Decode and the remade manga, it's revealed that Altirrans, Birdy's species, were the target of racism among other species and treated like lower-class citizens, especially following a terrorist attack.
 * The Federation: Technically where Birdy hailed from is called a Federation. Subverted because of the fact that the the human-like Altirrans are more or less lower-class citizens and treated like crap and that the Federation has a program to use Altirran DNA to bioengineer Super Soldier,.
 * Flash Back
 * Flashback Cut: . Outside of the sixth and maybe seventh episodes, the teasers to the second season of Decode could also be considered this.
 * Whole-Episode Flashback: Two episodes in the second season of Decode, showing Birdy's past. Also an entire volume of the remade manga.
 * Four Eyes, Zero Soul:.
 * Freaky Friday Flip/Man, I Feel Like a Woman: Happens in Decode -- . The manga is more appropriate to Man, I Feel Like a Woman since.
 * Gambit Pileup: deconstructed. In the beginning, there are several factions involved, along with multiple wild cards, a chessmaster, and neutral but interested parties. And that's just the first season, on the alien side. However, instead of there being any Just As Planned and I Know You Know I Know, bad intel and lack of information reigns supreme, with things devolving into a chaotic world where the law of unintended consequences dictates the outcomes of events more than anything else. No one really knows what the hell is going on, except maybe the viewer, and even they, who see a lot more than any given character must think quite a bit and infer a lot to figure out what really happened and why.
 * Genetic Engineering Is the New Nuke:.
 * Gory Discretion Shot: To varying degrees., in a way, and.
 * Hair Tropes
 * Anime Hair: Birdy in the original manga and OVA tended to have spiky bangs.
 * Fiery Redhead: Well, Birdy's got pink hair and it's only one of two (the other being white), but close enough. Similarly, Capella Titis has mostly pink hair with large sections of white.
 * Godiva Hair: Remake manga and Decode Birdy. The original manga and OVA versions, not so much.
 * Implausible Hair Color: Natsumi, a couple of Tsuotmu's other classmates, and a few other fall into this.
 * Multicolored Hair: Birdy's hair is a combination of pink and white. Depending on the version, the placement of the coloring varies. It's white on the right and pink on the left in the original manga and OVA; pink for the bangs, but otherwise white in the remake manga; and pink for the bangs and bottom of her mane but otherwise white in Decode.
 * White-Haired Pretty Boy:  Also, Cashew Gaze, who briefly appears in Decode and plays a slightly larger role in the remade manga, fills this trope and Dark-Skinned Blond.
 * White-Haired Pretty Girl: Nejula Gate, who's also dark-skinned. Birdy's a partial example.
 * You Gotta Have Blue Hair: Tuto's disguise in Decode has blue hair. The hair on Birdy that isn't white is pink.
 * Half the Man He Used To Be: How Birdy actualy kills Tsutomu in Decode.
 * Hand or Object Underwear" In the OVA, Tsutomu used his hands to cover himself up to run back to the bathroom to grab the clothes while his family was standing around.
 * Heroic RROD: In Decode 02.
 * Heroic Sacrifice: In the remake manga,  and in Decode,.
 * Hoist by His Own Petard: Hikawa in the OVA and Shyamalan in the first season of Decode. Hikawa was messing with a serum that was supposed to create Super Soldiers that had a history of mutating people into monsters and used himself as a subject, while Shyamalan tried to control the Ryunka, a weapon capable of killing everything on the planet.
 * Hollywood Silencer: The pistol at the end of episode 8 in Decode: 02
 * Hood Hopping: During a highway chase scene, Birdy and an Arkazoid leap across moving vehicles in rush hour traffic.
 * Hotter and Sexier: Birdy's uniform in the remake manga and Decode tends to cover less than the uniforms in the original manga and OVA.
 * Many do think this design is more aerodynamic, so it is pretty justifiable. Think of a gymnast's leotard.
 * Humongous Mecha: An episode of the Decode series has a giant mecha that resembles its pilot.
 * Human Alien: Birdy, Gomez, Christella Revi in the OVA. All Altirrans in Decode, and for once it is deconstructed. The Fantastic Racism applied to the human-like Altirrans is extended to Terrans themselves due to the resemblance. In this sense, it is contextually inverted, as Terrans are thought to be the look alike, not Altirrans. Further played with when it is revealed that Earth functions as a kind of refugee camp for Altirrans wishing to escape persecution, not to mention the usual hideout used by aliens-in-disguise.
 * I Have Many Names: In a meta sense, the series of robots that  and the Mecha-Mooks Birdy deal with. Depending on the incarnation, they're either called Arkazoids (original manga and OVA), Dolls (remake manga), or Marionettes (Decode).
 * Idol Singer: Birdy's alter ego of Shion Arita is one.
 * In-Series Nickname: Berserker Killer Birdy.
 * Journey to the Center of the Mind: The Freaky Friday/Man, I Feel Like a Woman and Whole-Episode Flashback examples, the former setting it off and justifying the latter, where.
 * Kill Sat: An episode of Decode has a Kill Sat intended to stop the main threat of the first season. As per usual with the trope, it failed.
 * Kick the Dog: Reversed in episode 6 of season 2 in the memory sequence with Nataru.
 * Lawyer-Friendly Cameo: Giroro makes one in episode 5 of Decode.
 * Lightning Bruiser: Birdy, and the Undine/Ondine even more so.
 * Mad Scientist
 * Magic Pants: The OVA played around with this. Initially Tsutomu's outfit did not change when Tsutomu changed into Birdy, leading to a girl in boy's clothing kicking monsters around. Later she incorporated her leotard-like uniform into the matrix so she'd be in her clothes, not his, after a transformation.
 * Mama Bear:
 * Mind Hug:
 * Mistaken for Gay: In Decode, Tsutomu's friends first meet Tuto when he brings Tsutomu his gym clothes and demonstrates a notable disrespect for his personal space. They decide to support the two's relationship.
 * Mistaken for Murderer: In the second season of Decode, several criminals escape, then one by one, each of their number is killed. The survivors assume wrongly that it's Birdy and that she was given orders to silence them for their involvement in the events of the first season.
 * Mood Whiplash: Decode can get very dark at times -- Let's go! Have a good time!
 * Morality Pet: Tuto, a shapeshifting AI, who assigned as a partner to Birdy in the remake manga and Decode. While what don't see how Birdy reacted to what she did to Tsutomu in Decode, in the remake manga she actually suggests covering it up until Tuto points out that he's recording and broadcasting what happened to her bosses and Birdy decided to help Tsutomu. While we don't know what happened in Decode between Birdy's reaching out to Tsutomu and their fusion, it should be pointed out that as Tuto doesn't exist in the original manga and OVA and hence Birdy in those was more willing to own up to her mistake without anyone telling her to do so.
 * Mundane Solution: In the OVA, Tsutomu figures out that one of the aliens can be defeated with ordinary dish soap. In the remade manga, gasoline does the trick, though it's Birdy that realizes it.
 * My God, What Have I Done?: Pretty much sums up Birdy's reaction to fatally wounding Tsutomu.
 * Naked People Are Funny: Tsutomu's dad catching Birdy in the bath (only Birdy was nude in the original manga, but both people were in the OVA and remake manga), Tsutomu running through the house naked (partly due to the aforementioned event and he was in a hurry to grab a cleaning agent to help Birdy stop Bacillus) in the original manga and OVA, and in the remake manga, Birdy using Tsutomu as a Person Puppet during that version of the said event as well, causing Tsuotmu's family and Hayamiya to wonder what's going on.
 * Names to Run Away From Really Fast: Double Subverted with Birdy's nickname, Berserker Killer Birdy. Turns out it doesn't mean The Berserker, it refers to the fact that she killed robots called Berserkers. The second subversion comes in when we find out these things give armies a run for their money.
 * Not in This For Your Revolution: Subverted. Birdy's mission in the original manga, OVA, and the remake manga is to arrest Christella Revi, but as Revi had to do with an attack that, Birdy has a personal axe to grind with her. While, this doesn't apply to Revi in Decode (Birdy doesn't know Revi's on Earth and her mission's somewhat different), in the second season, she also has a personal grudge against one of the escaped aliens she's supposed to recapture for similar reasons.
 * Obfuscating Stupidity: Birdy uses this in both seasons of Decode when in her alter ego of Shion Arita.
 * Older Than They Look: Hikawa in the OVA looks to be in his twenties, but.
 * Off-Model: Decode 02, Episodes 7 and 12, due to serious budget problems.
 * Ojou: Sayaka in Decode. Also an Ill Girl and.
 * Ordinary High School Student: Tsutomu, and even more-so his friends.
 * Parental Abandonment: Tsutomu's family in Decode, as mentioned in Batman in My Basement, isn't present.
 * People Puppets: Birdy at times tends to take control of Tsutomu's form, much to the latter's annoyance and anger. In the remade manga, she tries to use his body to fight much to his relief, as.
 * Posthumous Character:
 * Recurring Extra: In Decode, the two yakuzas whose car keeps getting damaged by Birdy.
 * Red Oni, Blue Oni: Hayamiya (tomboyish Fiery Redhead Genki Girl) and Nakasugi (blue-haired Ojou Yamato Nadeshiko).
 * The Revolution Will Not Be Civilized/Well-Intentioned Extremist/Your Terrorists Are Our Freedom Fighters: In the flashback we see in the second season of Decode, a lot of Revi's actions are an attempt to force the Federation to improve the lot of Altirrans so they aren't treated with racism and like lower class citizens anymore. A lot of her actions have included terrorist attacks on key government building, allying herself with members of the Federation's enemies, and  In the manga, the story is a little bit different. Revi is recognized as a genius, and quickly climbs to a high rank in the government science branch despite her race. Her terrorist attack on the central government is inexplicable, and followed by several more destructive bombings before disappearing to Earth.
 * is also starts out a Well-Intentioned Extremist, taking out the group most of the group of escaped aliens for the role in what happened in Season 1 of Decode. He slips into Moral Event Horizon when he kills two of them who disguise themselves as childern, one of them even deciding to leave the others in protest of what they're doing.
 * Roaring Rampage of Revenge: Nataru in Decode 02. Once he finds out the people responsible for the death of his friend, he makes sure they die/suffer horribly. Even Birdy has trouble against him initially when she tries to stop him.
 * Robot Maid
 * Robot Girl: Ondine/Undine
 * Samus Is a Girl: Not a strict use of the trope as Revi isn't an Action Girl, but in the remake manga and Decode no one, not even Birdy, outside a few people know that she is a woman. Averted in the original manga and OVA where it's pretty well-known what gender Revi is. In the remade manga,.
 * Secret Identity/Wig, Dress, Accent/Clark Kenting: In Decode, prior to being merged with Tsutomu and even afterwards, Birdy assumed the name "Shion Arita". This didn't stop a photographer, Tsutomu himself, or someone from her past from recognizing her. Averted in the OVA when Birdy's normal hair is visible and doesn't bother acting too differently.
 * Sent Off to Work For Relatives: After everyone in her family/household is dead, to causes both related and unrelated to the plot, Sayaka is sent to work on a farm with relatives.
 * She Who Must Not Be Seen/The Voice/Woman Behind the Man: Revi in Decode for the most part. The viewer does get to actually see her during the last scene of the first season of Decode, though.
 * Shock and Awe: In the OVA, Birdy can electrocute people by grabbing them and unleashing an electric shock into them. This is how she accidently kills Tsutomu and.
 * Shooting Superman: As seen once in the OVA and twice in Decode, shooting Birdy with a gun isn't really effective to take her down, though she will twitch or get knocked down upon the bullets' impacts and, as she expressed once in Decode, the impacts do hurt. In the manga, this is explained by a biological shield, but it's not invincible and with proper attacks.
 * Slasher Smile:  sports these as he kills the escaped aliens.
 * The Social Darwinist: Shyamalan (no, not that one) in Decode.
 * Space Police: Birdy is a space cop.
 * Spell My Name with an "S": The subtitles of the OVA prefer to romanize the last part of Birdy's name as "Altirra," though fans have also used "Altera." The English dub switched "Cephon" and "Altirra" around, resulting in "Birdy Altirra Cephon". Then there's "Altaria" (Uh...), used by Funimation on YouTube for Decode. The DVD release was contradictory, as the subtitles used "Altira", but the credits used "Altera". Though technically, "Altirra/Altera/Altaria" is only used to identify where Birdy's from and her species and really isn't offically part of her name.
 * Revi's android daughter name is either spelt Ondine or Undine.
 * Then there's.
 * Spoiled Sweet: Sayaka.
 * Superhero
 * Super Soldier: One of the villains in the OVA tries to create these via a serum. According to Decode,
 * Sweat Drop: Birdy does this upon finding a bomb just as it's about to go off in the OVA.
 * The Masquerade: Zig Zagged to hell and back in Decode. While the population at large is generally unaware of the aliens' presence, and many people don't believe in aliens, one may suspect that Masakubo's obsession with aliens and UFOs is more than crazy conspiracy theory paranoia. The non-humanoid aliens usually have some kind of disguise to make themselves look human and blend in, but many aliens have revealed themselves, making business deals with human companies and (possibly) governments. Even Birdy has the Shion Arita identity, but . No cover up efforts are made at all when , and everyone knows something weird happened when  . The government must have known something was up when  . But on the other side, some aliens living on earth might not even know they are alien, because they either were born there or moved when very small and their parents never told them.
 * Title Drop: Birdy does this in a made-up speech in the original manga.
 * Tokyo Is the Center of the Universe: Natch, though in season 2 of Decode
 * Justified in season 2, where.
 * An earlier episode implies that the amount of alien activity in Tokyo is actually not unusual for a city its size. Presumably every comparable city on Earth has lots of disguised aliens running around, too.
 * Training From Hell:
 * Twelve-Episode Anime: The Decode series. Literally in the case of the second season.
 * Tyke Bomb: In Decode, . In the manga,
 * Unstoppable Rage: . In the manga,.
 * Vague Age: Birdy's age isn't specified in either the OVA or Decode. In the OVA, she's clearly older than Tsutomu, but according to Tsutomu, she's too young to drink alcohol, which means she could be somewhere in the 17-19 age range. Doing the math in the Decode version, based on references to her past in the second season offer that she's probably at least 24 there.
 * Verbal Tic: In the Japanese version of Decode, Birdy as Shion Arita tends to accent the "u" sounds in words that have them and add "de arudesu" to a lot of sentences.
 * Voice of the Legion: During episodes 5 and 6,.
 * Voluntary Shapeshifting: Tsutomu and Birdy generally switch willingly, but there are still exceptions where Birdy takes over (or reverts back to) Tsutomu without warning.
 * "V" Sign: In the first three parts of the four part OVA series, the credits would end with an image of Birdy flashing this.
 * Water Source Tampering: This was Seichiro Hikawa's plan for the people of Tokyo, to turn them into "retro soldiers" by tainting the city's water supply with serum.
 * We Hardly Knew Ye: In the remake manga and Decode series, Tuto.
 * What Measure Is a Non-Human?: Both averted and played straight. Averted in that the various alien races pretty much agree they're equals (even though you can still spot a bit of Fantastic Racism here and there), played straight in that those very same alien races treat Dolls as little more than a commodity, despite them being clearly sentient.
 * What the Hell, Hero?: In the remake manga, Birdy actually considered trying to cover-up what happened to Tsutomu before Morality Pet Tuto pointed out that he was recording what happened and hence it was impossible, so Birdy decides to help Tsutomu after all. How serious she was is questionable, but she's reprimanded by her superiors none-the-less.
