کوماسان

Komasan is quite childish and is easily distinguished from a city slicker. He often ends his sentences with "zura" and he also uses the word "monge", a slang word meaning 'tremendous', when he's surprised or impressed. Due to this he seems to have a traces of an Okayama dialect. He is referred to as being a 'country bumpkin' and has very limited knowledge of urban life. He tries his best to learn as much as he can to present himself as a good role model to his younger brother, Komajiro.

Komasan spends most of his time roaming the city in search of delicious food, particularly soft serve ice cream, as well as going on adventures with his brother.
