About
Former twenty-something shut-in Mahiro Oyama was transformed into a girl by an experimental drug… and now he's a seventh grader, too! As he adjusts to schoolgirl life, he begins to take interest in girly topics like Valentine's Day, fortune telling, and even fashion and makeup! But can his idyllic new life continue when someone who seems to know his secret confronts him in the ladies' room?! (Source: [Kodansha USA](https://kodansha.us/product/onimai-im-now-your-sister-4/))
