Corticarte heard his singing and is healed by it, she fly to see who is singing it and finds Phoron. Corticarte reveals she wants him all for herself because of his pure heart and ask if he could sing only for her. Corticarte try to make a contract with him, but is interrupted by the spirits that were chasing her. We are back in the present and Phoron is cleaning the canteen of the university. Dantist are people who summon spirit through music, Phoron decided to be a Dantist after he met Corticarte, but being a Dantist, he cannot summon any spirit. Phoron try one more time to summon spirit through his One-Man Orchestra piano, but is unable to. He puts down the One-Man Orchestra, and remembers Corticarte saying "Nice song". He decided then to sing the same song he sanged that night Corticarte appeared in front of him. As he sing an unknown man takes out the seal of a room where a spirit was emprisonned. The dark spirit destroys everything that gets in its way looking for the man who sang the song. Eufin try to stop it, but her spirit is being overpowered by it. Phoron calls out Eufin's name and the spirit stop to look at the man who called out. The spirit approach Phoron, but stopped right in front of him. Inside the dark spirit was a little girl with red hair. It turns out that the Dark thing was just the shell, and inside was another spirit. Corticarte. Except that she is in her "kid" form. Phoron doesn't realize she is Corticarte until she actually tells him. Corticarte picks up where they left off and finishes the contract she was about to finalize twelve years ago.
