Chapter 1
Taichi awakens to find himself lying on the field at Yamaboshi High School. Confused about where he is, Taichi quickly realizes that he is in Isolation Space. Taichi senses how dark and ominous his environment is and decides to walk towards the school building. Suddenly, Nagase dives at Taichi, hugging him. Glad to be reunited, the pair try to find the other members of StuCS. The two try their cell phones but learn that they are out of any service area. With no options left, they enter into the school building where they meet their classmates, Watase Shingo, Setouchi Kaoru, and Nakayama Mariko, who have taken note of the weird phenomenon. After they conclude their conversation, Taichi and Iori continue searching for Inaba and the others. They eventually arrive at the school pool where they meet five students and ask if they have seen Inaba, Aoki, or Kiriyana. The other students reply no and suddenly, one of the students starts to act strangely. She repeatedly asks if anyone can see her and begins panicking, even crying a bit. Taichi and Nagase immediately recognize she is suffering from a phenomenon and wait for the effects to wear off. When it does, the girl explains that the phenomenon causes someone to be invisible to all senses and forget that the phenomenon exists for its duration, essentially making them a ghost. Taichi and Nagase part ways with the girls and hear a scream from the gymnasium. Arriving at the gym, they find a boy screaming, "Get away from me, Get away from me! Dont come any closer!" The guy frantically flees from the gym. The other students in the gym explain to Taichi and Nagase that their phenomenon is to randomly cause one person in the group to see everyone else as an enemy and be afraid of them. At that moment, Nagase and Taichi realize that in the world they are trapped in, everyone is experiencing Heartseed's supernatural phenomenons. Nagase and Taichi continue their search for Inaba and the others but instead find a group of first years having a argument. Taichi recognize that the phenomenon the two are experiencing is "Desire Unleash". Taichi and Nagase break up the fight and explain the phenomenon they were experiencing. Suddenly, Katori Jouji, the Student Council President, announces on the school speakers for everyone to meet in the auditorium.
