It drops you into a world of pantsless children and then, somewhere around the point you stopped laughing, it makes your throat tighten. Yuye Hua walks in fully clothed and that's the whole joke and the whole weapon: fabric as armor in a lightless place, played for gonzo slapstick one minute and gut-punch the next. The language trick is the flex nobody else pulls off, Chinese for the waking world, Japanese for the other side, so the switch itself tells you where you are before a single line lands. The action animation is genuinely loose and mean, closer to Excel Saga energy than anything a streaming algorithm would greenlight. Yes, the comedy and the melodrama never fully shake hands, and half the people who start it bail. The half who stay end up defending it to strangers for years.

Yuye Hua, a clever high school girl, is abruptly pulled into another world. The place is sunk in darkness with no light at all, and the only people living there are children dressed in nothing but underpants. She is the one person who arrives fully clothed, and here clothing is the most powerful weapon there is, which puts her on course to become this world's heroine. Garments can be called forth as strong fighters known as Spiclo, and a conflict between light and darkness is under way. The story plays out as a comedy across 12 episodes of an ONA.
