Nurarihyon no Mago Chapter #10
Nurarihyon no Mago Episode #5
Anime, Manga and Game
Gozumaru (牛頭丸, Gozumaru) is the Gyūki Clan's young head.
Gozumaru has dark grayish hair that it is tied up at the back and covers half of his face, out of admiration for Gyuuki but on his left side rather than the right.
Mezumaru claims that when he lets his hair down he looks like a girl with a bobbed hairstyle, something the Gozumaru says that is never showing to anyone else.
Cool and cruel, he considers the main house to be inferior to the Gyūki Clan. He has a great amount of confidence in his battle skills, at one point expressing interest in challenging Ryūji and Mamiru. He is fiercely loyal to Gyūki and willing to do anything the latter requests. Despite having experienced Rikuo's competence first-hand, Gozumaru still dislikes him. However, he also seems to have a grudging respect toward Rikuo, as he admits that the latter hides shrewdness behind a "good guy" facade.
During Gyūki's conspiracy against Rikuo, Gozumaru separates Rikuo and Tsurara in order to eliminate the latter. When he is about to deliver the finishing blow, Rikuo appears and rescues Tsurara by defeating Gozumaru despite not being in full "Night" form mode.
As a stipulation to Gyūki's pardon, Gozumaru and Mezumaru are forced to take up residence at the Nura House. In the anime, Karasu Tengu ropes both into looking for the missing Nurarihyon. Later, when the executives of the Shikoku Hachijūhakki Yakō appear at the Nura house, Gozumaru attaches a string to Gangi Kozō which he and Mezumaru use to track down the former. They trap him in an abandoned warehouse and roughhouse him to get information on the Shikoku yōkai, but when it starts raining and he gains the upper hand, they are forced to flee.
In the manga, he and Gozumaru are sent to the Shikoku Hachijūhakki Yakō's base on a reconnaissance mission. Disguised as tanuki, they are discovered by Gangi Kozō, who Gozumaru defeats easily, and use him to sneak into a restricted area. When they find the room containing Maō's Hammer, they are captured by Shikoku yōkai and heavily injured by Tamazuki. Subsequently, they are rescued by the Sanba Garasu and return to the Nura house to recuperate.
He wields a katana and is able to control creatures via string, though he is not as proficient as Mezumaru in the latter. In the anime, he shows himself capable of attaching this string to someone to utilize for tracking purposes.
