Gorisuke

Gorisuke receives relatively little individual characterization compared with Gorilla and Ruri Gachi. He appears mainly as one of the younger Gachi siblings and participates in the crowded, energetic atmosphere of their home.

Because the series gives him limited independent focus, his characterization is tied closely to family scenes rather than a distinct personal storyline.

Gorisuke is an ordinary human child with no established supernatural abilities or named techniques. The exaggerated strength associated with his eldest brother has not been established as a specific ability of Gorisuke.

Gorisuke appears through chapters exploring Gorilla Gachi's family life. These stories reveal that the intimidating-looking schoolboy spends much of his time helping his busy mother care for his younger brothers and sisters.

The younger Gachi children also become important when the family's OrderMaid, Nasu-san, malfunctions. Gachi refuses to simply leave work to his younger siblings and takes responsibility himself, reinforcing the protective role he occupies within the family.

Gorisuke's presence therefore contributes primarily to the domestic side of Gachi's characterization rather than functioning as a separate plotline.

Gorilla Gachi is Gorisuke's eldest brother and regularly helps care for him.

Ruko Gachi is Gorisuke's mother and runs the family's animal hospital.

Ruri Gachi, Goriji Gachi and Rumi Gachi are Gorisuke's siblings and fellow members of the Gachi household.
