Two assassins adopting a kid on Christmas should be cynical wish-fulfillment. Instead, it's genuinely gutting, the show treats a found family forming between broken people as something that actually costs them. The comedy lands because it earns every sincere moment; Kazuki and Rei become fathers without ever stopping being exactly who they are. It looks beautiful doing it, moves fast enough to never feel sentimental, and understands that the hardest part of loving someone is letting them change you.

Two professional assassins find themselves in the last situation they ever expected: parenthood. Kazuki Kurusu is an outgoing contractor who loves gambling and women, while his quiet roommate Rei Suwa, trained from childhood to kill, spends his downtime on video games. Their world changes on Christmas when four-year-old Miri, alone and searching for her father, stumbles into the middle of a hotel hit on a mafia boss. The plan was to return her to her mother, but Kazuki quickly warms to the role of parent and Rei's guarded heart soon opens too. Feeding her, playing with her and handling nursery school runs prove harder than any job, yet both men, now called papa, choose to give Miri a normal childhood despite the risk to their careers. The result mixes action, comedy and drama with everyday family life.
