A brother so obsessed with keeping his sister safe he won't let her leave the house gets turned into a cat, and suddenly he has to watch her live without him. The supernatural reset doesn't fix what was broken between them, it just changes what he can do about it. A single episode that knows exactly what it's doing: taking the smallest, quietest premise and letting it sit until you feel the weight of it.
Naruto and Anzu inherit their parents' wealth and live as orphans, but Naruto's suffocating overprotectiveness keeps his sister locked away from the world. On her 16th birthday Anzu runs off with a kitten, and when Naruto comes after her, an accident kills all three. Their parents decide it is too soon for them to die and bring them back to life. The catch: Naruto wakes up as a cat. Anzu finally gets to live on her own, unaware that her brother is still hovering over her in feline form. She only notices that her furry companion acts just like him, so she names it Naruto in memory of the brother she believes she lost. The result is a comedic, supernatural romance OVA with an ecchi streak.
