The Yakuza's Guide to Babysitting - S01

Tooru Kirishima is infamous in the underworld as "The Demon of Sakuragi," a man who doesn’t hesitate to use violence when needed. After nearly ruining a peace treaty, his boss gives him the toughest assignment yet: looking after seven-year-old Yaeka Sakuragi, the boss’s beloved daughter. The job is meant to teach Tooru the weight of responsibility for another life. At first, they clash-Tooru doesn’t know how to connect with a child, and Yaeka struggles to share her feelings. But over time, the hardened yakuza enforcer and the quiet little girl begin to understand each other. Through their differences, they discover that family isn’t always about blood ties.
