School Babysitters - S01

After losing both parents in a fatal plane crash, teenager Ryuuichi Kashima has to adjust to his new life as the guardian of his younger brother Kotarou. Ryuuichi manages to stay friendly and kindhearted, but Kotarou is a reserved toddler still too young to understand what has happened. At their parents' funeral, Youko Morinomiya, the stern chairman of an elite academy, approaches them and decides to take them under her care. There is one condition, though. In exchange for a roof over their heads and enrollment in the school, Ryuuichi must become the school's babysitter. A babysitter's club was set up to support the female teachers at the academy by looking after their infant children, but the club is severely short-staffed. So now Ryuuichi is responsible not only for his little brother, but also for a handful of toddlers with dynamic personalities.
