The episode starts with 12-year-old Shion day dreaming and not paying attention during class. It's his birthday today so after school he heads over to his friend Safu's house to have a party with her and her grandmother. The storm outside starts to turn into a typhoon, so Shion heads home. Once home, he goes out on his balcony and screams. An alarm goes off inside so he heads back in. When he looks back at his window, a strange boy is standing there, who seems to be injured. After gaining the boy's trust, Shion proceeds to treat his wounds. We find out the boy's name is Nezumi ("Rat"). Shion discovers that Nezumi is a wanted fugitive - a VC - but he still aids Nezumi by giving him food and letting him sleep in his bed. The next day, Nezumi is gone and the Security Bureau arrive at Shion's home to question him about the situation.
