Ten-year-old Takuya has a new job: to look after his baby brother Minoru…looks like it’s time to put on the kid gloves! Young Takuya has it tough. Since his mother passed away, he’s had to take care of his baby brother Minoru while their father works the long hours of a Japanese salaryman.

Ichika and Ma-bo run away from their crowded home…but it’s not long before the peace and quiet of Takuya’s house get on their nerves! At the office, Takuya’s father juggles a computer crisis, a stressed-out coworker, and a gang of lackadaisical office ladies. On a school trip to Kyoto, Takuya tries to figure out girls…while Minoru figures out how to survive without his big brother. And Takuya meets a down-on-his-luck manga artist, only to make an enemy of the artist’s son!
