Sushi Neko

Sushi Neko aka Nekota-san appears in many guises through the show, as an aspiring sushi chef, a delinquent teacher, a businessman with curious sales and management techniques and also as the suicidal superhero Sushi-sushi-man. Hindered by his cat-sized brain, he nevertheless takes on the challenges of a human world with mostly disastrous results.
