Magical Girl Chiki Chiki

Run of the mill college student Aizawa Yoshiyuki meets Chiki-Chiki who appears in his apartment out of the blue. She is a witch in training who decided to choose Yoshiyuki to get one wish granted. But as she is still learning, her spells aren’t perfected and things don’t go as she expects. One thing leads to another and Chiki-Chiki ends up living with him while Yoshiyuki continues on with his normal life; but he soon learns that that's next to impossible with a magic user in the house.
