Mahiro hasn't stepped outside in years. His room is his whole world: futons, snacks, and a stack of erotic visual novels he knows by heart. His little sister Mihari has had enough of watching him rot in there, so she cooks up a plan to drag him back to normal life. The plan starts with a pill. He wakes up one morning and the mirror shows a small girl staring back. That's him now. Mihari did this. She watches him freak out, and honestly, she seems pretty pleased with herself. The change doesn't wear off, no matter how long he waits, so Mahiro has to figure out how a former shut-in actually lives as a cute girl. School, noise, new people, all of it. Mihari calls it rehabilitation. Mahiro calls it a nightmare. But the days keep coming, the house keeps getting louder, and somewhere in the middle of the chaos he starts meeting people who actually want to be around him. Will he ever get his old body back, and does he still want it if he can?
