Idea Factory Touhou Spell Carnival

Touhou Spell Carnival is an officially recognized derivative work based on the Touhou Project. Gensokyo - a remote land, isolated from the outside world, where humans and youkai live side by side. One day, Reimu Hakurei, the shrine maiden of the Hakurei Shrine, discovers mysterious pillars rising in various locations throughout Gensokyo. These pillars signal the beginning of the Spell Carnival, a festival hosted by Yukari Yakumo, where participants must use their spell cards in battle. To uncover the true intentions of Yukari Yakumo, who has so suddenly initiated the Spell Carnival, Reimu Hakurei joins the fight for the spell cards.
