The Yakuza's Guide to Babysitting - S01

Tooru Kirishima's reputation reaches far across the underworld. He is best known as "The Demon of Sakuragi," a man who will not hesitate to use violence when he thinks it is needed. After nearly wrecking a peace treaty, his boss gives him the hardest job he has ever had: looking after seven-year-old Yaeka Sakuragi, the boss' precious daughter, so Tooru can learn what it means to be responsible for another life. At first, the two do not get along, since Tooru has no idea how to talk to Yaeka, and the young girl is not used to showing her feelings. Over time, though, they begin to understand each other despite their differences. The fearsome right-hand man of a yakuza boss and the child he has to protect are about to learn that family is not always bound by blood.
