The Yakuza's Guide To Babysitting, Vol. 2 by Tsukiya

A notorious enforcer continues his babysitting assignment for his boss’s quiet grade-school daughter, and everyday milestones—sports day, school projects, and visits to her hospitalized mother—pull them into awkward, heartwarming territory. He fumbles through gentler tasks while warding off minor underworld trouble, and their growing trust softens his rough edges as he learns to balance protection with tenderness, finding family in the unlikeliest place.
