Madotsuki MUGEN

Madotsuki as she appears in M.U.G.E.N

M.U.G.E.N is a modular 2D fighting game engine that makes it possible for any character to be created and used in-game as a fighter.

More information on M.U.G.E.N and how it works can be found on the Mugen Wiki.

Madotsuki is one of the playable characters available to download. The data package is available here.

Curiously, in the data package there is a unplayable Monoko that just stays in one place.
