Kim Gu is the Cartoon Character Type Personal Attribute of Tac.
Kim Gu, 'The White Western Tiger', transferred to Arang industrial high school, a place where 'survival of the fittest' is law.
Kim Gu wanted to be a 'good student' and keep the promise he made to his father who told him: "do not fight in school". He tried to stay as quiet as possible even when he was bullied. Inevitably, he used his fist and unintentionally showed his true power to one of the biggest gang factions in the district, the Cheong-Cheon society. Once he showed his true power, there was no going back.
Unlike most delinquents who smoke, Kim Gu is usually seen biting candy as "smoking is harmful to the body".
He is a close-range fighter that utilises powerful fist attacks. Sometimes, when he uses a big technique the name of the technique is written in big red colors.
