Shin Megami Tensei: Tokyo Mokushiroku

A satanic program triggers a disaster on a flight to Tokyo, unleashing invisible demons that destroy the plane, killing all passengers except Akito Kobayashi, the program's creator and a supporter of hell. Kojiro Soma, Akito's former classmate, is shocked to see him return to school, now confident and arrogant. As classmates are attacked and demons reappear in Tokyo, Kojiro realizes Akito's transformation. Akito seeks to use magnetite, a substance linked to human souls, combined with his demonic software, to unleash a devil plague. A magnetite source is present in Kojiro's class. As Akito's plan spirals out of control, Kojiro must discover his own inner strength to confront the most powerful demon.
