A girl finds an alien in her sleepy city and decides to help it leave. That's the entire story, delivered with the patience of someone who knows a single episode is enough for a real moment. Inzai Aru Aru Monogatari trusts you to care about a stranger just because she does, no apocalypse required.

Shirushi Nishizumi is a ten-year-old girl living in the city of Inzai when something unexpected falls from the sky: an alien stranded far from home. The creature's ship is completely drained, and without a specific energy source called "Aruaru," there's no way to get it running again. The single-episode slice-of-life ONA adapts a four-panel manga made to promote Inzai, a city in Chiba prefecture.
