Something Like a Cat

At first glance, Nanika is a mysterious creature that looks like a black cat. Eat melon bread from the wrong place, and even if you want to put on a collar, why does it slip and stick to the ceiling like Spider-Man? Nanika should be uncomfortable, but master's elementary school student: Renya-kun accepts this with the attitude "I did't know that cats are such creatures." New cat manga (?) that cat lovers and non-cat lovers like!
