Magikano

Yoshikawa Haruo is an ordinary middle school boy whose main ambition is to live a long life. He lives with his three younger sisters, without their parents, and has no idea that they possess magical powers—or that he may have powers of his own that have yet to awaken. One day, the mysterious and beautiful Mamiya Ayumi appears. She is a witch who needs to turn Haruo into a man to break a curse placed on her when she was young, so she becomes a maid in his home. Though the boys at school adore Ayumi, class president Kurusou Yuri dislikes her. Serious and orderly, Yuri has been in love with Haruo since they were children.
