Gugu is a young boy from Takunaha who works at Booze Man's shop.
From a young age, Gugu and his brother, Shin, have been working as servants for various families. Because he was so young, Gugu mistook one employer as his family and was confused when they moved away but didn't bring Shin and him along.
A few years later, Shin and Gugu promised each other to work hard and earn money to build a big house.
