Gugu

Gugu (グーグー) is a young boy from Takunaha who works at Booze Man's shop.

Appearance
Gugu has blond hair and light blue eyes. He used to wear a light brown chameleon mask outlined with a red and black stripe, but has since switched to a more elaborate chameleon design gifted to him by Booze Man when he got older. He also wears tan-colored shorts with a red and white pattern on the left leg and a white and blue stripe at the bottom.Gugu is shirtless both as a child and a teenager later on, and covers part of his stomach with a white bandage.

As a child, Gugu had a short, thin stature and a distinctive pot-belly due to the alcohol-containing "organ" Booze Man installed. Four years later, from his maintained physical training, Gugu boasts an extremely muscular build, with his pot-belly noticeably absent. He also stands taller than all his companions at Booze Man's shop.

Personality
Despite being so young, Gugu has a somewhat jaded and pessimistic view on life, which is likely due to his poor upbringing and his older brother using up all the money they were trying to save. Yet, when Rean gives him her ring that he could have spent on himself when he finds his brother beaten up and withered in an alleyway, he decides to give him the ring instead; showing that he has a caring side under his supposedly bitter exterior.

If his mask is brought up, Gugu gets very defensive and scared of people trying to see his face, believing his accident to have scarred him so much that people run away when they see his face. Given that people have called him a monster without his mask, he 's not wrong to keep his face hidden. He also falls into a spiral of despair when Beer Gramps uses him to distill alcohol and hates feeling like a tool and a monster.

He gets shy and nervous around Rean, who he has a crush on, which leads to his adoptive family, wondering why he just tells her he likes her and that he was the one who saved her life not too long ago.

When Gugu reaches his teenage years, he's become more mature and wise. He also loses all negative feelings towards his mask, saying that he likes his look despite being annoyed by people trying to take a picture of him and his mask after his revival in the new era.

Background
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.

Abilities
Gugu has become very strong after years of training. Gugu has excellent cooking skills and is responsible for cooking meals for everyone. When he leaves, Beer Gramps and Pyoran greatly miss his food. With the help of his modified mask and by using the alcohol in his stomach, Gugu can breathe fire. When he shuts the lid of his mask, the pressure created sets fire to gunpowder balls concentrated at the nose.
