Shadows of the Azure

Shadows of the Azure is a fanfiction made by Chris X (yes, the man behind Super Sentai vs. Super Sentai). Once again a crossover, it involves both Blaz Blue and the Persona series, but mainly Persona 4. It is sort of a celebration of the announcement of Arc System Works' Persona 4 Arena, but he intends to finish it.

The story takes place after the True End of Persona 4 and the True End of Blaz Blue Continuum Shift. The Investigation Team returned to the Midnight Channel one day, but was eventually attacked by a mysterious creature, stronger than any Shadows or even Izanami. Thoroughly beaten, the Investigation Team is whisked away to somewhere else by the creature as it wreaked havoc to the Midnight Channel, in actuality thrown into the world of Blaz Blue, where Yuu Narukami along with Teddie were found by Ragna the Bloodedge and Taokaka, and had to travel with them while uncovering the mystery behind the attack, seemingly getting blurry in their memories, as well as eluding whatever Terumi Yuuki is plotting. Along with that, dreams of meeting a mysterious man with a blue butterfly seemingly becomes common... and Shadows started appearing in the Blaz Blue world...

It is very much promised that the author will create Shadow versions of the Blaz Blue cast, so keep your fingers crossed for the likes of Shadow Ragna, Shadow Jin, etc.

Tropes associated with Shadows of the Azure

 * Butt Monkey: No matter the universe, Yosuke always became one, especially when he's stuck in Rachel's dimension.
 * Canon Name: The author uses Yuu Narukami instead of Souji Seta or other names.
 * Cooldown Hug: This is Litchi we're talking about. In one chapter, she did this twice on a distraught Yukiko.
 * Expy: The mysterious enemy bore a strong resemblance to Nyarlathotep the Crawling Chaos, giving the possibility that the Investigation Team is attacked by Nyarlathotep himself, but since he's last known to be sealed, it's still unclear who this enemy is.
 * Fandom Nod: Rachel remarked that her George XIII that she sent to chase off Yosuke has been getting a little rusty. Which was generally fandom's opinion on the drop of tier levels of Rachel from Calamity Trigger and Continuum Shift.
 * Green-Eyed Monster: Tsubaki again... this time to Yukiko.
 * Groin Attack: Bang committed the same mistake he did to Noel, this time to Chie... the result is a critical hit to the nads. He shrugs it off fine, though.
 * He Who Fights Monsters: Used as the basis of Shadow Ragna's Hannibal Lecture to Ragna, citing that he doesn't care about how many people die, and how will he turn into a monster against his promises to Rachel to stay human, as long as he can get his one wish of killing Terumi in revenge.
 * Headbutting Heroes: Kanji and Jin are shaping to be this.
 * Heroic BSOD: Yukiko was completely shaken when she overheard what Relius planned to do with her (dissecting). Thank goodness Litchi was there to calm her down, allegiance be damned.
 * The Nicknamer: As usual, Taokaka. The nicknames she came up for the Persona 4 cast (and their Personas)...
 * Yuu: White Head Guy
 * Teddie: Bear Guy
 * Izanagi: Black Guy
 * Kintoki-Douji: Fat Rocket Guy
 * Only Friend: At the moment, with the allegiance problem of her former friends, Tsubaki only had Litchi as a friend, and the arrival of Yukiko and Litchi's closeness to her is slowly driving Tsubaki to the edge further.
 * Pungeon Master: Like usual, Teddie. He even pun-ized Ragna's name into "Ragna the Bear-Edge". Of course Ragna didn't like it.
 * Shadow Archetype: The premise of the fic is to introduce Shadow versions of the Blaz Blue characters. Thus far it has Shadow Ragna.
 * Shout-Out: Ragna takes the explanation of Midnight Channel just as much as Ichigo Kurosaki taking the explanation of Soul Reapers for the first time.
