Majimoji Rurumo

まじもじるるも

Shibaki, a high schooler stuck with a reputation as the school pervert, tries a witch-summoning spell he finds in an old library book and actually gets one: an apprentice witch named Rurumo, who grants him a wish without taking his soul in payment. When he wishes to see her again, she drops back into his life with an assignment: she has to get him to spend 666 magic tickets before she can become a full witch. What Rurumo does not know is that every ticket shortens Shibaki's life, and the last one will end it.
