Shaman King: Funbari Spirits, is a cel-shaded 2D style fighting game released in Japan only. It is not to be confused with Shaman King: Power of Spirit, a game produced by Konami to go along with the 4kids Entertainment dub. This is a pseudo-sequel to Shaman King: Spirit of Shamans, a 2D fighting game for the PlayStation. Interestingly, this game is based upon the Manga and is the very last Shaman King game to be released in Japan.
Funbari Spirits features simple controls and plays quite like a 2D fighter despite being 3D. There is a 2 player mode, adventure story mode, mini game mode, and a free play mode along with training mode. The game also has voices from the original anime, as well as colorful cel-shaded graphics.
All of the main characters are present as playable characters, along with a few exclusive-to-this-game-only characters.
