Yusaku Godai didn't get accepted into college on the first try, so he's studying to retake the entrance exams. But living in a dilapidated building full of eccentric and noisy tenants is making it hard for him to achieve his goals. Now that a beautiful woman has moved in to become the new resident manager, Godai is driven to distraction!

A hostess at Godai's work runs off and leaves her two young children in his care. Not sure what to do, he brings them back to Maison Ikkoku, where Kyoko volunteers to help look after them while Godai tracks down the mother.
