With Christmas coming, Henrietta asks Jose to spend Christmas with her. While on a mission, Triela shoots a suspect against the orders of her handler, Hilshire. At base, she mulls over the fact that Hilshire always gives her the same Christmas presents. They are then sent on a mission to apprehend Mario Bosh, a retired Mafia leader. They succeed in finding him, but he manages to escape. As he is about to be killed by the Mafia, Triela saves him, and allows him to leave to be with his daughter. Overhearing this, Hilshire asks her what she wants for Christmas, and she asks for another bear. On Christmas day, however, she receives a present from Mario as well.

Mais Triela le laisse s'enfuir et à leur retour, en plein préparatif de Noël, le Père Noël vient rendre visite aux jeunes filles...
