A middle schooler turning into a fire-breathing dinosaur when she gets mad is the most honest metaphor for puberty anime has ever attempted. The show plays it completely straight, which makes every transformation funnier and more true than if it was trying to be clever about it. Gauko isn't a superhero origin story or a magical girl setup, she's just a kid whose worst impulses have teeth and scales, and she's learning to live with that as much as everyone around her is.

Naoko Watanabe is an ordinary tween girl living in Japan, apart from one strange power that is as much a curse as a gift. Whenever her anger climbs past its limit, she changes into Gauko, a dinosaur girl who breathes fire. The comedy slice-of-life ONA runs 20 episodes and builds its humor around the gap between Naoko's everyday life and her explosive alter ego.
