Goriji

Goriji has limited independent characterization in comparison with Gorilla and Ruri. He appears mainly as one of the younger children in the Gachi household rather than as the focus of separate stories.

His scenes contribute to the lively family atmosphere around the animal hospital and to the responsibilities placed on his eldest brother.

Goriji is an ordinary human child. No supernatural abilities, unusual powers or named techniques have been established for him.

Although Gorilla's physical strength is routinely exaggerated, the series does not establish that Goriji possesses the same level of strength simply because they are brothers.

Goriji is introduced when the story explores Gorilla Gachi's life outside school. Bondo and the others learn more about the large family their friend helps support while his mother works.

The family's OrderMaid, Nasu-san, normally assists at the animal hospital, but her malfunction forces Gorilla to take over reception instead of going out with his friends. Goriji and the other younger children are among the siblings Gorilla refuses to burden with the work.

His appearances consequently reinforce Gorilla's characterization as a dependable eldest son.

Gorilla Gachi is Goriji's older brother and regularly helps care for him.

Ruko Gachi is Goriji's mother and the working parent at the center of the Gachi household.

Ruri Gachi is Goriji's older sister.

Rumi Gachi is Goriji's younger sister, while Gorisuke Gachi is his younger brother.
