Touhou Hyouibana: Antinomy of Common Flowers is a 2D fighting game built on the Touhou Project's cast, pitting spellcard-wielding characters against each other in fast one-on-one duels. Screen-filling bullet patterns and special moves tied to each character's mythology define the combat.

It continues the tradition of Touhou fighting spin-offs that translate the shooter series' danmaku aesthetic into a competitive arena format. Fans of anime fighters and the Touhou universe are the natural audience.
