Kimitaka Matsumae

Shibaki is a high school boy only interested in girls. However, he has been branded as the most perverted boy at school, and the girls go out of their way to avoid him. When he finds a book in the library about how to summon witches, he tries it as a joke; unexpectedly, though, the book works, and a cute witch named Rurumo appears to grant him a wish. Shibaki helps Rurumo and she in return refuses to take his soul. After some time, he thinks about his meeting with Rurumo, and wishes he could see her again. His wish is granted immediately, as Rurumo falls from the sky and crash-lands in front of him, tasked with getting him to use up 666 magic tickets that grant wishes before she can become a witch again. However, according to Rurumo's familiar, what she does not know is that each ticket he uses will shorten his life span, and, when the last ticket is used, he will die.

Kill Me Baby is the touching story of Yasuna, a normal (?) high school girl, and Sonya, her best friend who happens to be an assassin. Unfortunately, little Sonya's trained assassin instincts often work against her and others in her daily high school life, as Yasuna's often-broken wrist can attest to. She just wanted a hug, but she ended up with a broken neck. Isn't it sad? No, it's hilarious.
