Buddy Daddies - S01

On Christmas Eve, four-year-old Miri Unasaka arrives in Tokyo all by herself, looking for her father. The bright lights and cheerful holiday mood lead her to a big hotel and a man holding a cake that looks delicious. But without knowing it, the child has just walked right into the middle of a carefully planned, foolproof scheme to assassinate a dangerous mafia boss. Professional assassins Kazuki Kurusu and Rei Suwa share a home, running from memories of their grim childhoods and keeping their feelings at a distance. When their mission goes wrong and they end up taking Miri home with them, there is only one reasonable thing to do: return Miri to her mother. But the girl's innocent laugh and pure view of the world quickly win Kazuki over, and he secretly enjoys playing the role of a parent. It is not long before Rei's guarded heart also makes room for Miri. Miri's every move is unpredictable, and Kazuki and Rei find that raising an energetic child is harder than any of their missions. Even though it puts their careers at great risk, Kazuki and Rei, both taking on the affectionate nickname "papa," decide to give Miri a normal childhood despite all the odds stacked against them.
