Youkai Kori Kassen (妖怪狐狸合戦 , "Catastrophe War of Fox and Raccoon dog") is a Touhou fan game written in Danmakufu by raichu, released in full on 27 March 2013. At first, it resembles a typical Touhou game, but plays more like Fairy Wars.
The game's system is based around transformation power items, which can be used to activate a square that transforms all bullets it touches into even more transformation power items. The main strategy is to activate this square when there are many bullets in the vicinity, in order to produce a large number of items.
The game has a selectable route system. At the beginning of the game, five stages are available to choose in any order. After three of the five routes have been taken, the final stage will be available, but the player can still play the other stages first. As you complete each stage, the game gets more difficult.
