This is the 9th Touhou game. It was released in August 2005 at the summer Comiket 68 convention. This game is a versus-type shooter like Phantasmagoria of Dim. Dream, and has very different gameplay from the past three entries in the series. The story puts the characters in an investigation on why the flowers of Gensokyo are blooming out of season and more than usual. Initially playable characters include Reimu, Marisa and Sakuya as usual (as well as two other characters from previous games), but the list adds on as the player progresses in the storyline of each of the players.
