/// MISSION BRIEFING

When Akio Mori is almost hit by a truck, his friend Makoto Ozaki does everything he can to save him. Since then, Akio has been having the strangest and most recurring dream of a beautiful girl appearing before him. He has been having this dream for two months, and the girl's identity has always been a mystery until now. Noticing the girl from his dreams passing by him in real life, Akio is shocked when she runs up to him, hugs him, and suddenly disappears. Completely perplexed by the experience, Akio returns home, but instead of finding comfort, he is forced to face an abrupt truth when, walking to his house, he sees a photograph of his funeral on display. Realizing for the first time that he did not survive the accident from which he believed Ozaki saved him, Akio decides that the only thing he can do is ask his best friend for help.
