Yuji Shiozaki's fight manga Ikki Tousen took the figures from epic Chinese historical novel Romance of the Three Kingdoms, reincarnated them as Japanese high school students, and had them beat the clothes off each other. It's been adapted into nearly a half dozen anime, almost as many games, and now a free-to-play social game.
Ikki Tousen: Burst Fight is developed by Marvelous Entertainment, who previously made 2007 PlayStation 2 game Ikki Tousen: Shining Dragon. (Tamsoft developed the other two Ikki Tousen games.)
Card game Ikki Tousen: Burst Fight will do what it says on the tin, and feature clothing battle damage, specifically when the character performs a "Burst Break." The game for the GREE and Mobage platforms will be free-to-play with virtual items like outfits for sale.
