When they enter the apartment they accidentally run into a teenage girl, Nanami Kumatani (played by Ayaka Maede) who was in the pact but backed out at the last minute out of fear. The girl tells them about 'Ricki' (played by Yûko Nakamura) and agrees to show them her suicide manual in exchange for letting her look on the roof of their office.
