A bullied genius codes a demon summoning program as the ultimate revenge tool, then watches it spiral into something he can't control. The 1987 OVA doesn't explain itself clearly, the timeline jumps, the logic fractures, the whole thing feels like you're witnessing a ritual you weren't meant to understand. That confusion is the point. The atmosphere does the heavy lifting instead, all neon and dread and a synth score that sounds like your computer is possessed. This is where Megaten began, before the franchise learned how to package its own chaos into something digestible. It's a raw nerve of a story pretending to be a coherent plot, and franchise devotees still feel it.

Two high school students, Akemi and Yumiko, share a mysterious bond rooted in past lives. Akemi is a computer genius who is bullied at school, and he writes a program that can summon demons so he can take revenge on his tormentors. Yumiko, a new transfer to his class, feels she has met him before, but he is too absorbed in his machines to notice her. After school, Akemi calls up the devil Loki on his screen, and chaos follows. The OVA adapts the first of Aya Nishitani's Digital Devil Story: Megami Tensei novels, blending horror, adventure and the supernatural.
