In 1987, Jusho High School, the teacher named Ohara Yokoo was introducing a transfer girl student from Sapporo who is Yumiko Shirasagi. Yumiko then bowed and smiled. Yumiko nodded at the students' introductions. A teacher named Iida came out the bathroom and bowed to a student walking by, turning out to be Akemi. Akemi then walked in to Ohara's class and walked by Yumiko without bowing. Ohara then put her hand on Yumiko's shoulder and told her to try her best. Everyone then stand up and bowed, except Akemi. who was on his computer. Akemi then reminded Ohara to come in the computer study room. Ohara then dropped the chalk remover. Yumiko then smiled and walked up to Akemi, then bowed. Akemi then told Yumiko to not get too involved with him. When school was over. Yumiko then looked back at the school and spoke to herself she came to a awful school then turned up with her school bag. Yumiko then saw a person walking up and it turns out to be Ohara. Then, in the computer study room. Akemi was on the computer until Ohara came. Akemi then put an electrical hook on her head from the computer. Akemi then typed something on the computer that made Loki come up on the screen. Yumiko was eavesdropping the whole time until she turned around and saw the demon Cerberus, and she passed out. Later at night, Yumiko was inside the book store and checking out books. The next day, Ohara then made an announcement in her class and said all of them were going to the computer study room. Yumiko then was confused a little until her friends showed up and made a circle, telling her to come. One of her friends, Kanou grabbed her a little too rough and Yumiko told her it hurt, but Kanou didn't care. Will Yumiko and Akemi make it pass this demon journey? Let's see as we go back to Jusho High School.
