In the spirit of a lengthy recent forum thread, here is a three to four point summary:
- Game developed by Kenka Bancho team; similar inspiration - deliquent street brawling
- Also worked on by Senran Kagura producer, so features fanservice - "Girls will cheer the guys on during their fights to heat them up. If you defeat enemies in front of the girls, you’ll power up. There is even a chest grab-and-bury-your-face element. (There’s the Takaki influence.)"
- Plot involves deliquents on an island designed for brawling.
- Published by Marvelous, so there's every chance this could make it to the west (XSEED are Marvelous' western arm)
