I'm not that interested in the game, but the last one had Hinata from Haikyuu in it, so I'll assume he'll come back and will get a character intro video too? yes/no/maybe?
he was an assist only character in the last game and i don't think this game is doing assist only characters since it's a tag fighter, he might show up in the story mode since light is in it but i don't know
Rukia is playable, that's it so far
