After experiencing a horrible nightmare of suffering defeat across the rubble of Tokyo, Rin Kobari, accompanied by the exasperated talking bird Mosuke, starts her day in Ginza to help a certain old lady. Rin happily sees off the old lady, but she quickly goes on the defensive as a familiar sight—the magical girl who defeated her in her dreams—suddenly appears from far away.
The chase leads her into the underground rail and into an off-limits area. Mosuke rambles on his uncomfortable feeling, only to be ignored by Rin, who bravely steps in despite admitting that she is scared herself. Soon, upon reaching the end of the passageway, they see an ominous red light.
