Nobody watching this expects a geology lesson to feel like sitting with friends who actually care about what they're teaching. The shorts strip away plot entirely, leaving just two girls in a room explaining why rocks matter. You finish each one feeling like you learned something real without ever being made to feel dumb for not knowing it already.

The cast of Asteroid in Love returns in a set of twelve short ONA episodes from 2020, each one devoted to explaining a piece of astronomy or geology. The shorts pair that educational focus with light comedy and a relaxed slice of life feel, so the lessons come across as casual chats rather than lectures. KADOKAWA streamed a new episode each week on its YouTube channel for a limited period, and the collection was later added to the Blu-ray and DVD release of the main series. The brief running time makes each segment an easy companion piece for fans of the original show.
