Reborn receives a mysterious letter from the Ninth Boss. Tsuna is late and leaves without having breakfast. As he leaves, Nana Sawada talks about the new transfer students that transferred to Namimori due to escape any more earthquakes that might happen in their area, as one had just occurred. As Tsuna runs to school, he sees the group of transfer students and feels guilty of causing the earthquake. However, this guilt immediately turns to fear as the girl glares at him.
Just then, Reborn surprises him by appearing next to him and tells him about the Vongola's Inheritance Ceremony, where Tsuna would be officially named as the tenth boss, much to Tsuna's surprise. As Tsuna and Reborn continue to walk to school, a bird suddenly falls behind them, dead. Tsuna arrives at school and is welcomed by Gokudera, Yamamoto, Kyoko and Hana. The four are excited about the new transfer students. The bell rings and the teacher begins to introduce the two of the seven transfer students that would join their class. The girl, Shitt P! arrives and everyone is confused about her appearance and way of talking, none more so than Gokudera, who thinks that she is an UMA, an "unidentified mysterious animal". The next transfer student is a boy named Enma Kozato, who reminds Tsuna of the old him, quiet and gloomy. Meanwhile at the school's reception room, a girl transfer student named, Adelheid Suzuki, tells Hibari and tells him that that room belongs to the Liquidation Committee, and she will act accordingly if he resists.Later that day, Tsuna and Reborn are walking home when they see Enma Kozato being beaten up by two men. Reborn kicks Tsuna into the fight but did not fire the Dying Will Bullet, causing Tsuna and Enma to be beaten up. As the two recover, Tsuna tries to help Enma with his scattered text books when Tsuna's Vongola Ring seems to affect Enma's ring. Seeing this, Enma immediately leaves, leaving Reborn thinking that he wasn't an ordinary transfer student.
