Kansen Sodom

When a mysterious organization releases a virus into an ordinary city, instead of killing anyone, it completely obliterates everyone's self-control. The school near ground zero gets hit hardest — teachers, students, nobody is immune to the overwhelming surge of desire that follows. What starts as a normal day spirals into full chaos pretty fast, with the entire social structure of the school breaking down as the virus spreads and inhibitions disappear entirely. The tone is intense and doesn't really let up once things get going. It's not trying to be subtle about what it is — this is a single-episode OVA from 2018, adapted from a web manga, and it commits fully to its premise without much hesitation. The focus stays on the psychological tension of losing control alongside the physical chaos unfolding around the characters, which gives it a slightly more grounded feel than pure absurdist hentai. If you've already worked through Kansen 5: The Daybreak or Kansen 2: Inzai Toshi, this fits neatly into that same universe and thematic territory — familiar setup, familiar escalation. If you liked Kansen 3: Shuto Houkai's approach of using a city-wide crisis as the backdrop for its content, this follows that same structure. It's a short watch by design, so it doesn't overstay its welcome. Know what you're getting into going in, and it delivers exactly what the premise promises.
