The mischievous yellow dog that is a deviant for meat, money, girls and their school uniforms whenever he's not loafing.
Wooser is an mysterious animal who happens to live alongside Rin and Len's home in the Internet, which turns out to be a world. He is mainly an meat eater and is a sucker for getting money, being around girls and hopes to possess multiple schoolgirl uniforms.
Wooser's name happens to be a play on the name of the original creator of the series, Yoshiki Usa. Not much else has been revealed on the creation process of him so far.
Wooser is a yellow creature who most likely resembles a dog, but appears to have stubby arms and legs. The dot on his face is not a mouth, but is a nose instead. Him, Darth Wooser and Ajipon each don't appear to have a mouth, but they are able to speak and eat.
Despite his cute and adorable appearance, Wooser is lazy most of the time and is even considered to be a pervert because of his schoolgirl uniform affinity. He also has a rather crass and selfish attitude toward almost everyone around him and even has a royalty complex within himself.
