In this chapter, we learn that the monster that attacked the school was a centipede, which is about the size of a basketball court. The other monsters, however, were able to defeat the school's leader, aoki, and her partner. The two of them were badly injured, and they were sent to the alien for treatment. When they arrived at the alien's hideout, they found out that the alien was the one who had saved them. They were worried about what was going on at the school, so they came to meet the alien. The alien tells them that he needs them to sign a secret contract that they will keep the secret of their mission. He asks them to kill the monster if they have the power to do so. They agree, and the alien gives them two coins that he took from a collector in the mountains. The coins will allow them to transform themselves into younger people. They decide to use the coins to become street performers.
