Chances are that if they do put in Rival Schools characters, it will be between him, Akira Kazama, and (Demon) Hyo Iwamano.
Kyosuke also appeared in Capcom VS SNK 2, so I don't think he is not a possibility!
Yes!! I literally know nothing about Rival Schools tho, but he stood out in the demo, especially when he spoke to Jin and Xiaoyu as if they were fellow students.
Rival Schools is a 2.5D fighter with simpler imputs than Street Fighter, and many kinds of specials.
The story is about weird kidnappings in a Japanese city. These kidnappings are all linked to schools, and students fight with each other trying to find the truth. The story is not very important, but the game still gives a weird focus on it due to a special Japan-only game mode (more on it later) AND voices cutscenes in the PSX version (not to mention a lot of these cutscenes change depending on which duo you have chosen).
All the characters are awesome Capcom-fied versions of shoenen and school manga stereotypes. They are all a likable bunch.
The PSX Japanese version of the game takes the school aspect up to eleven and adds a SCHOOL SIM MODE filled with goofy events, fanservice for everyone (and I mean everyone), a character creation mode and you can even befriend and almost date the characters, and said school sim mode got a sequel and added two (goofy) characters to the roster too. Sadly none of this came overseas and I doubt it will ever get translated.
The game in general is filled with 90s anime stereotypes... it's filled with anime references
(Tiffany might as well be Swan White......) and one of the PSX exclusive characters, Hayato Nekketsu, got designed by a famous mangaka who specializes in hot blooded burning high school manga.
There is nothing not to love in Rival Schools. It's the best. A lot of the characters are just too crazy...
Now, onto Batsu: he is the usual Ryu character in terms of fighting style (although it is Hideo, the old teacher, to get a shotoclone moveset).
He starts out as a bitter lone wolf in search of his missing mother, but soon he opens up to his classmates and becomes friendlier. He loves his friends, he is stubborn, easily embarrassed, easily excitable, easily angered, and of course he loves JUSTICE!!!111. Batsu always listens to his heart and his fist before he listens to his brain.
He is incredibly moe and he made me discover how much I love Nobuyuki Hiyama's voice
I suggest Rival Schools to everyone. It's simply a good game. If they did a remake of the first with updated graphics I would be happy as much as if they did a third one. Knowing Tiffany and Hinata popped up in SFV made me smile.
I really hope this new MvsC adds a Rival Schools character. This lovely 90s fighter should always have a bit of spotlight.
