Stray Little Devil vol 04

Pam Akumachi is an energetic 13-year-old junior high student full of curiosity. One day, when Pam and her friends try to summon the "benign devil" her grandmother used to talk about, the magic circle goes out of control and Pam is sucked within and transported to a strange parallel world where angels and devils coexist with no humans in sight. There, she meets a mysterious man, who says he will show her the way back to her world, but only if she becomes a full bona fide devil. And the only way to do so is by training under a master devil as a devil's apprentice. Under the watchful eyes of Master Devil Lizyerra and her other apprentices Raim and Vine, Pam begins to learn what it takes to be a devil.
