Labyrinth of Touhou

After an extended stay at the Scarlet Devil Mansion, Reimu Hakurei has failed to notice that the boundary between Gensokyo and the outside world has begun to fall apart, and only realizes it when a huge rift in space opens above them. Accompanied by Marisa Kirisame, Remilia Scarlet, Sakuya Izayoi and Patchouli Knowledge, she begrudgingly goes to explore the mysterious dimensional rift so that she may continue lazing around without distractions.
