A non yaoi manga

Natsume is just an ordinary kid, except he can see spirits, just like his grandma Reiko could. Reiko, though, used to bully the spirits, and bound them to her will in the Book of Friends. Now that Natsume has inherited this book, a never-ending stream of spirits is coming after him. With the help of a spirit cat; (who really just wants Natsume to die so he can have the book), Natsume spends his days dissolving the contracts that bind the spirits and trying not to get killed.

Plot: After their parents are killed in a plane crash, Ryuuichi and his younger brother Kotarou are taken in by the chairman, who they never met before, of an elite academy. Ryuuichi becomes the school daycare's new babysitter.

Kurosaki Mafuyu was a juvenile delinquent and head of her gang before her subsequent arrest got her expelled from high school. Now that she’s transferred to a new high school, she’s determined to become an “ultra-shiny, super feminine high school student.” But with a new friend like Hayasaka-kun and a homeroom teacher like Saeki Takaomi (who may be more than he seems), will Mafuyu really be able to live a girly-girl high school life!?
