One day, a strange girl wakes the main character, Kanata, up in a strange room. He is taken to school, but he doesn't remember it at all.

A while later, he remembers the girl introduced herself to him last night, "I'm Ayari. My job is Santa Claus!" Kanata now completely remembers why he came here and feels down, "Ah, I really ran away from that home...."
