Three oni kids saving human-oni relations with superpowered underpants is exactly as unhinged as it sounds, and that's the point. Tsutsuji, Tsuyukusa and Himawari each get a distinct comedic lane instead of blurring into one generic trio, so the pantsu-transformation gimmick actually lands as a running bit instead of a one-note gag. The 3-minute format is the real flex here, this is a team that knows comedy pacing and refuses to let a joke overstay its welcome, which is why it survives 60 episodes without feeling padded. If you grew up on Mitsudomoe or Yuru Yuri's rhythm of rapid-fire character-driven bits, this scratches that same itch but with a magical-girl skin grafted on. It's dumb in the way that's actually engineered, not lazy, and that's the whole appeal.

Oni have had a poor reputation among humans for centuries, and three oni girls set out to change that. Sunny Tsutsuji, cool Tsuyukusa and boisterous Himawari rely on the onipan, special underpants with superpowers that let them take human form. They enroll at an ordinary Tokyo high school, throw themselves into school events, work to liven up the town and sometimes even perform as idols, all to improve how people see oni. The comedy comes in short episodes of about three minutes each.
