Asura's Wrath is an anime-inspired take on Buddhist stories, but some new DLC announced in Japan will add a legendary character from another tradition. A single screen of new DLC released by Capcom shows Asura facing off against a distinctly Street Fighter IV-looking Ryu, complete with SFIV-style HUD elements and the traditional side view. Even the background imitates a familiar Street Fighter backdrop while simultaneously making sense in Asura's world.
Capcom didn't offer any more details about the DLC beyond that one screenshot -- no date, no price, nothing. But that teaser is enough to guarantee we'll be paying attention.
