As the Tokyo-bound flight approached its destination, a malicious program hijacked the aircraft and unleashed undetectable beings that caused it to crash, leaving only one survivor - Akito Kobayashi, a devoted follower of the devil. After Akito returned to his old school, his former friend Kojiro Soma was taken aback by his arrogance and newfound conviction. As Tokyo was plagued by legendary monsters and classmates went missing, Kojiro realized the dark intentions behind Akito's plans. Akito intended to use magnetite, the essence of the human soul, and his diabolical software to unleash legions of infernal creatures upon the world. The key ingredient he needed was in Kojiro's classroom, but when his plans spiraled out of control, it was up to Kojiro to summon his courage and face the ultimate demon in an epic battle.
