It's the third night chiaki has been staying at the hotel, and he's heard that there's been an "off-limits room" in the hotel. Apparently, someone has died in the room, and the room has been sealed off. He wonders what's going on, and decides to go to the teachers and tell them about it. He's not sure what to make of it, but he thinks it's some kind of "vengeance spirit" of a "very tortured soul master" . The girls are bugging him about the whole trip, and they've been bugging him to give them a concert. He doesn't want to, but the girls keep bugging him, and when he starts singing, they all shut up. He can't believe they're not scared of him. He gets the scoop on the girls: they all came to the hotel on a school field trip. Apparently the hotel stopped hosting them for a while, and some of the students got sick, and a teacher got sick.
