Bodacious Space Pirates/WMG

Descriptions and sketches of Marika's pirate captain identity broadcast on the news will sound/look nothing like her.
Perhaps leading her to mutter something like "Did they even look at me when we hit that ship?"
 * Nope; her real picture is broadcast all over the galaxy in ep 12.

Marika will have several Chekhovs Skills
The trailer starts with Marika flying a small spacecraft in her school uniform, then later in the video she's piloting a space fighter with a near-identical cockpit in her pirate captain outfit. Her swordfighting skill and other skills useful in operating the pirate ship may also apply.

Marika's father was murdered.
They said it was food poisoning, but they could've meant someone put poison in his food.

The cyber-attack on the Odette II is being performed by a member of Bentenmaru's crew
It's a test to see how Marika will handle such a situation. Note that Kane assigned her and Chiaki to be the only ones on the bridge at the time the intrusion happened.

The Odette II will sail as a privateer again
While her shields and beam cannons have been removed, the Odette II isn't much changed from her last configuration as the Hakuchou. Given that she's also been outfitted with a fleet flagship's command and control suite, it's quite possible she may lead a taskforce, consisting of her, Bentenmaru and Barbarossa. As for her crew, the Yacht Club are prime candidates.
 * Or worse, Jenny will use her father's connections to obtain a Letter of Marque of her own. And then the galaxy will learn to fear the Yacht Club.
 * As original poster for this WMG, that is both awesome and terrifying at the same time. And further to that, perhaps it's less that Jenny obtains a Letter of Marque, and more that the ancient original Letter of Marque for the Odette II is revived, to the current surviving descendant of her original captain, one Captain Doolittle. In the generations since the war, Captain Doolittle's descendants have left piracy for commerce shipping, carefully building up their war chest for the day the ancestral ship returns to war...
 * It happens in the third book.  Not yet known if this will appear in the anime.
 * The third book begins with ep 14.
 * What actually happens is that Marika tries to recruit a new crew, but is foiled thanks to Kenjo Kurihara; Chiaki suggests she recruit the Yacht Club, which she does, and they take Bentenmaru out in the next episode. And the crew was infected by the pathogen.

The protagonists are The Theme Park Version of Space Pirate... literally.
The independence war that created the first Space Pirate has been ended 120 years ago, and all factions are said to be united by the Galactic Empire. However, the local government still maintained the Privateer on the basis that they rob people at least once every 50 days, for 120 years. Given that there are no other governments that they can fight against, it seems rather improbable that such system was maintained for that long without any interference.

Though, the reaction of (most) passengers of the Princess of Apricot showed that they are actually excited to be visited by the Space Pirate. How is it so? Because they are The Theme Park Version of Space Pirate... literally. The romance of Space Pirate lived on even after the war, and the local government decided instead of disbanding them, it would be better to keep them into the current harmless way, so that they can be used as an attraction to the wealthy cruiser-goers. The reason why they are required to rob every 50 day is to ensure the attraction has some kind of regularity, and the shipping company can cover the loss by insurance (which, in turns, funded by the increased tourism due to the pirates).

As such, the story is actually a literal Space Opera of Space Pirate, playing with the trope.

Then why some of the people treat it as a Serious Business? It might be a case of Enforced Method Acting, so that our rookie protagonist can be (slightly) more realistic when "robbing" the cruiser. Another reason may be because the pirate ships are still fully-functional warship with (generally) competent crew, so that in situation where there are real enemies, they will be conscripted into the navy, thus actually risking their lives.


 * Well, with the ending Cliff Hanger in episode 8, it looks like a Civil War is about to erupt. If a war breaks out, all bets are probably off. So all that showboating Marika is being forced to do will likely be utilized for real, and she'll probably end up having to kill a lot of people to save lots of others...
 * It Gets Better afterwards, but not before showing off the combat ability of Bentenmaru against military vessels.

The Golden Ghost Ship is a TARDIS
Think about it. There's this ghost ship that's being sighted in extremely distant locations with an improbably short time between these sightings, and it's explained that ships as old as the ghost ship wouldn't have FTL, so there's no way it would be able to appear as it does...unless it's a TARDIS with its chameleon circuit stuck on "Golden Ghost Ship!"
 * Oh, the Time Lord controlling it is Marika's father. He faked his death just so he could screw with people for the lulz. The revelation will cause Marika to use the TARDIS to go back in time and really poison his food so that he really does die.
 * Apparently the Golden Ghost Ship process some kind of FTL jump capacity, as it utilised subspace for fast travel between dangerous space.
