Juichi Kito

His human disguise is a round-faced, middle-aged man whose skin carries a gray cast. The black hair sits short and tidily combed, and his black eyes are typically shut. He dresses in a brown V-neck sweater vest over a white collared shirt, with black trousers below.

Upholding the clan's inherited duty, Juichi assisted his mother Naki Kito in delivering humans to the Tsuchinoko, keeping the creature placated so the village volcano would not erupt.

In the Cursed House Arc, he and his family observed Jiji invite Momo and Okarun over, then followed Momo to the mixed baths with his brothers intending harm, a scheme undone when Turbo Granny's luck collapsed the springs. Back at the house with Officer Tsuru's aid, Juichi quizzed Okarun about Jiji's soccer team to test his story, then helped catch Jiji lying and beat both boys senseless. He fought Momo until Naki used the Jennifer Lopez Anaconda to fling her into the lair, praising his mother's strength before the family was shoved in and devoured by the Tsuchinoko.

Spat out alive, the Kitos pursued Momo as she hauled the corpse to stop the lava, were obstructed by Manjiro, and were assaulted by the Evil Eye. After the village survived, Juichi and his kin were arrested while Naki stayed at large. In the Typhoon Human Arc, Naki broke him out with Juhiko and Jumanieru, and they boarded Momo's flight. He overpowered Raiya before taking a hit from the blind Unji, then was pelted with luggage by Momo, whom he and Naki angrily blamed for their exile. When the engine failed and a typhoon dragged sharks into the plane, Juichi panicked repeatedly while Naki told him to fend for himself. Riding the revived Mongolian Death Worm, the family fired sharks back at the storm until Jiji's Evil Gun ended it. A giant shark then swallowed the worm and the Kitos and was kicked toward the moon, where Juichi remarked on the thin air as Naki, certain it was Momo's plot, renewed her thirst for revenge.

Juichi is an able hand-to-hand fighter, skilled enough to gain the upper hand over Raiya in a one-on-one clash.
