Thomas is a young raccoon with a slim physique and short stature. He has a fairly long, light-colored coat with black markings around his eyes that resemble a mask. His tail is long and ringed. He wears a typical Japanese kitchen outfit.
Due to his low participation in the series, there are not many details of the personality of this character. He is quite charismatic, trustworthy and very sociable. He usually shows a fairly relaxed attitude towards his environment. On Legoshi's first work day at the restaurant, everyone noticed the discouragement he showed, and Thomas was one of the people who invited him to the Black Market to satiate his abstinence from eating herbivore meat.
