A man watches his bicycle wheel spin. That's the entire premise, and it has no interest in becoming anything else. The comedy lives in the refusal to escalate, in the absolute commitment to letting a mundane object be exactly what it is while something quietly shifts in how you see it.
A young man wakes up one morning to discover his legs have transformed into wheels. Not metaphorically. Not gradually. Literally. Two perfect, functional wheels where his shins used to be. He has no explanation, no warning, and absolutely no idea how to navigate the world like this. What starts as pure physical comedy spirals into something wilder as he attempts the most mundane tasks: getting dressed, buying groceries, going to work. Every surface becomes an adventure. Every staircase becomes a crisis. The absurdity compounds when he realizes nobody around him seems particularly concerned about this development, treating his wheeled condition as just another Tuesday. The OVA plays this premise completely straight while milking every possible laugh from the collision between a normal life and an impossible situation. It's the kind of high-concept gag that could only work in anime: deranged, energetic, and committed entirely to the bit. Perfect for anyone who appreciates comedy that refuses to explain itself and just commits fully to the weird.
