Rantarou said to the others to ran to the final gateway, so he can Hack into the Main Monitor, of the entire school.

Everyone was against leaving Rantarou behind, but the gate were beginning to close and Rantarou told them to hurry and go. Some we're still against, but decided to ran as they don't want to waste his sacrifice in this escape.
