King of Pleasure

His life is genuinely rough — bullied at school, ignored at home, just grinding through days that blur together, and Ryouichi is only a high school kid. Then Chihiro shows up, a childhood friend who transfers into his class and has no idea what she's walking into. When she learns about a brain injury Ryouichi suffered as a kid — one she unknowingly caused — the guilt hits her hard. She offers to do anything to make it right. He takes her up on that. What follows is a dark, uncomfortable look at someone who's spent years feeling powerless finally deciding to reach for control, starting with the people closest to him. It's not a feel-good story. The show leans into moral ambiguity without much interest in easy answers — Ryouichi isn't framed as simply a hero or a villain, and that tension is what makes it interesting beyond the surface content. If you've watched Discipline or Bible Black and appreciated when adult OVAs actually try to build out a character's psychology rather than skipping straight to the explicit material, this scratches a similar itch. It's only three episodes, adapted from a visual novel, so it moves fast — but the setup between Ryouichi and Chihiro carries enough weight to keep the character dynamics engaging throughout. Go in knowing the tone is dark and that it takes the revenge angle seriously.
