Nobody remembers this one, and that's the joke the movie is in on. Ultra-Nyan treats a cat-versus-crow war like it's the most serious diplomatic crisis in anime history, then immediately undercuts itself by being a cat who solves problems by being insufferably charming. The premise is absurd, the stakes are zero, and that's the entire point, a comedy that knows exactly how silly it is and leans into it without apology.
Haruka's otherworldly cat companion returns for another round of cosmic chaos. Ultra-Nyan is back from the stars, ready to protect his adopted home, but this time the threat comes from an unexpected direction: the local crows have declared all-out war on the cat population. With feline society thrown into turmoil, Ultra-Nyan must track down what sparked this sudden avian uprising before the conflict spirals out of control. Alongside Haruka and their friends, the mysterious space cat puts his alien abilities to work solving the mystery. What started as a simple reconnaissance mission becomes increasingly absurd as the gang uncovers just how ridiculous the crows' grievances truly are. Packed with slapstick comedy and the same warmhearted charm that made the first adventure click, this sequel leans into the premise's inherent goofiness. Ultra-Nyan's deadpan approach to increasingly silly situations keeps things entertaining, whether he's negotiating interspecies peace treaties or simply trying to understand why birds and cats can't just get along. It's lighthearted adventure that doesn't take itself seriously for a second.
