Chapter 1



 "SAYA OTONASHI A high-school girl and a member of a track and field club, she lives peacefully with her family in Okinawa. However, she cannot recall anything of her past except for the previous year. Yet, she is unaware of the upcoming threat of fate waiting at the doorstep.

'' HAGI A tall and impeccably handsome cello player, who seems to know Saya from before, but everything else remains a mystery. He holds the key to Saya's destiny... " ''

The chapter opens with a field of roaring flames and bodies of monsters and humans everywhere. On the piled up bodies, engulfed in blazing flames, a figure stands with an open blade, panting in the heat.

Saya wakes up sweating all over: she has had the nightmare again. It is a bright sunny morning in Okinawa and Saya has woken up late as usual. Her day starts with a ruckus as she hurries downstairs where her father George and younger brother Riku have been preping for the inevitable. Saya hurries through everything. A fussed Kai arrives to see the source of ruckus, ending up being forced to give Saya a ride on his bike. While Saya goes back to her room to get her cellphone, George reads out the weather prediction saying it'll rain in the afternoon and Riku wishes he could see the cello man on street again. Rumor has it that the man is looking for someone as he travels on with his cello. Riku gets told off by their dad as he sounds girly. Saya finally gets outside and a plane soars off in the sky. She watches the plane go and a deja-vu sort of feeling crops up in her mind; she thinks it is related with her past. Kai taunts her for spacing out but she asks him the name of the plane. He replies it's a B52 and tells her off for thinking too much. A rumbling noise from Saya's tummy gives Kai another excuse to call her a glutton. But Saya walks off telling she'll walk school rather than go with him.

At school, Saya practices her regular high-jump. Seeing that she's all messed up, Kaori asks her what's going on. Saya mentions Kai but it's not about him teasing her. She gets interrupted by a senior student who commends Saya's jumping skills and asks if she was in the track and field club at her middle school as well. Saya stutters and replies that she doesn't remember anything before the past year.

Elsewhere, a young boy inquires the condition of 'mice A and B' amidst a group of people. One of them answers men are working hard to track them but so far unable to succeed. The head scientist Van addresses the boy as 'monseiur Charles' who then tells him to call Charles only. Charles then shows his missing right arm to the others and tells them to hurry up and catch the mice as fast as possible, otherwise all of Okinawa would end up like that. The men recount their words to do all possible. Then they trace something heading off to Koza.

Back in Koza Commerce High School, Saya is sitting with her? food, thinking about what happened back in early morning. Suddenly a third-year student, Mao Jahana, appears in front of the 'amnesiac' Saya and invites her to play the lead role in a drama for the high school festival. Saya rages at her but Jahana mutters that if Kai's little sister starred in the drama, he would definitely come to school. Kaori figures Jahana-san's famous for chasing Kai. Jahana corners Saya and does not hesitate to tell that she dislikes her. She further tells her off for staying with Kair under the same roof without being blood-related to him. Saya doesn't get how anyone can like Kai that much and points out his flaws. Mao retorts that Saya's not normal either and Kai is the no. 1 bad boy in the locality as well as the baseball ace while he was in first year. Saya is stunned since she didn't know that he played baseball. Right then, Kai enters and announces it's time for her to go to hospital since he'll be busy in the afternoon. Without listening to Saya or noticing the blushed Jahana, he grabs her by the wrist and takes her away.?
