The Yakuza's Guide to Babysitting

The reputation of Tooru Kirishima is well-known across the criminal underworld. He is best renowned for being "The Demon of Sakuragi," a man who will use force if it is required. In order to teach Tooru what it means to be in charge of another life, his boss gives him the most challenging responsibility he has ever had: caring for Yaeka Sakuragi, the boss' beloved daughter, who is seven years old. The two initially don't seem to get along because Yaeka is a young girl who isn't used to expressing her emotions and Tooru has no idea how to talk to her. Despite their differences, they eventually grow to understand one another as time goes on. A yakuza boss's terrifying right-hand man is going to discover that family is not always defined by blood ties when he must defend a young youngster.
