It weaponizes a cat's hurt feelings against you for twenty-odd minutes, and you let it. Kuro sulking off to find a master who isn't Rin is the kind of low-stakes premise that only works if the show actually loves the character, and this one does. The comedy-to-ache ratio lands exactly where early Blue Exorcist lived, goofy right up until the moment the two-tailed demon cat's loyalty stops being a joke. The art doesn't coast either, it's the same polish the main series wore, spent entirely on a familiar throwing a tantrum. Be honest about what it isn't: no new backstory, no expansion of what you already know about Kuro and the master he lost, and the runtime taps out before it can dig. It's a snack, not a meal, but it's a snack about a cat deciding who he belongs to.
Kuro the demon cat is fed up. After one too many slights from Rin, he storms off to find a master who actually appreciates him. His search takes him through a parade of potential candidates, each more unsuitable than the last. A swordsman obsessed with training. A scholar buried in ancient texts. A monk who prefers meditation to chaos. None of them understand what makes Kuro special, and none of them can match the peculiar chemistry he shares with Rin, even if neither would admit it. What starts as a spite-fueled mission becomes something closer to self-discovery. Kuro learns that replacing someone matters far less than understanding why you actually want them around. Between comedic misadventures and surprisingly earnest moments, this OVA captures the heart beneath the bickering that defines his relationship with Rin. It's lighthearted and character-driven, perfect for anyone who enjoys watching banter-based friendships get the spotlight they deserve.
