In this chapter, we're introduced to a new character, the girl from Hirokazu's house. She's Hiro's younger sister, and she's just returned from a trip to Japan. We're also introduced to her younger brother, who's now in college, and we learn that he's a little jealous of her brother's new friends. The girl is psyched to be back in her room with her brother, but she can't figure out how they're supposed to get back to her room.
