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, carry the weight of past lives neither fully understands. When Akemi, a brilliant outcast tormented by classmates, creates a computer program capable of summoning demons into reality, he believes he's found the perfect tool for revenge. Instead, he unleashes something far darker than anticipated. The digital and supernatural worlds collide as demons pour through the digital gateway, threatening everyone around them. Yumiko becomes central to stopping the chaos, her connection to Akemi running deeper than either realizes, rooted in reincarnations neither remembers. Caught between occult horror and technological nightmare, the two must confront not just the creatures they've unleashed but the forces that bound their souls across lifetimes. This 1987 OVA pulls from foundational source material that helped shape the entire Megami Tensei franchise. Expect atmospheric dread, existential questions about destiny and revenge, and the visceral collision of 1980s digital anxiety with genuine supernatural terror. Perfect for viewers drawn to horror that questions what happens when human ambition meets forces beyond understanding.
