Komeiji Koishi, an extra stage boss of Subterranean Animism, goes to upper Gensoukyou to catch a fish for dinner, but she forgets to bring a fishing rod. Seeing the Scarlet Devil Mansion nearby, she decides to borrow one from them, and from there on Komeiji Koishi's Heart-Throbbing Adventure really begins...
Not all creepy Koishi pictures count. Look for things such as sharp claws or the phrase, "My hat is my friend, it helps me relax."
