Shin Megami Tensei: Tokyo Mokushiroku

A deadly incident aboard an airliner leaves Akito Kobayashi alive, protected by the demons he has learned to summon through a computer. Returning to Tokyo, he brings that power into the lives of people who still remember him as an ordinary classmate.

His old friend Kojiro gradually recognizes the danger as students come under attack and supernatural forces spread through the city. Akito's ambitions unleash more than he can command, forcing Kojiro to confront both their shared past and a hidden power of his own.
