Youkai Watch ♪ Planetarium: Koma-san kara no SOS! Black Hole e Let's Go da Nyaa ♪

Keita heads out with Whisper and Jibanyan to observe the night sky for a school assignment, expecting nothing more dangerous than a quiet lesson among the stars. Instead, they receive an urgent call from Komasan, who has somehow been swept toward a distant black hole.

Joined by Komajiro, the group ventures into space to bring him home. Their rescue becomes an energetic journey through the mysteries of gravity and black holes, where curiosity and quick thinking are as important as courage.
