Kazuki and Rei take on a job during Christmas.

With their new charge, the assassins' lives become less easy, especially when a new job comes up.

The guys decide it's time to say goodbye to Miri as they take her back to her mother but there'll be one last time on the playground first.

Taking care of Miri is a full-time job, but the boys may have found their salvation: Daycare; but enrolling her won't be as easy as it looks.

Miri's presence is hurting the buddies' finances.

Kazuki is determined to be a parent for Miri.
