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."

There's only one thing Ichika wants for her birthday (besides Minoru's undying love), and that's the royal treatment! At her birthday party, family and friends are forced to bow to the precocious toddler's whims...until Ichika goes a little too far. Then Takuya runs into a familiar face--and a group of gangsters--at a racetrack. And Takuya grows closer to a gruff new teacher when he's given the assignment of keeping a daily journal...
