After the transaction is complete, the principal tells the students that he will do all he can to give them their freedom. He tells them that once they go back to the future, they will be able to bring back their partner. He explains that the primordial world is in turmoil because of the "nothingness" of the past. Some soul beasts have already entered the academy, and he needs their strength to bring their partner back and destroy these creatures. The principal explains that his power is called "sorrow energy" and that he was born with this power. He asks the students to cooperate as long as they help him and his brother escape from the institution. The sister tells the principal that she does not care if the nothingness exists or not, but only wishes for her sister's well-being. She says that she wants to give the opportunity before hers is too precious, and that she will pay the counter if the principal does not keep his promise to give her freedom
