Customer B

The customer has a short beard with a mustache and wears a black hat and yellow shades and jacket, he wears brown pants but does not wear a shirt.
He is the very first victim of the nyandemic

At first, he was a customer who seems cheerful and acknowledge the cafe and all the cats and attempting to interact with them.
However, after pouring a cat food into his hands he requested from Kunagi. He starts transforming infront of them and even eats the cat food he poured on his hand, much to everyone's horror.

What is left of him is a brown tabby cat, where all the cats start rubbing agaisnt him. Causing them to become infectious and gain ability to turn any humans into one of them.
