Kaira as a kid.

Kaira is a humanoid Yo-kai with medium-length, dark blue hair. His eyes are dark blue as well, though there are dark red circles around his pupils, which are oblong like those of a snake. He wears what appears to be a black shirt with a v-neck cut, and black pants. Half of his body is clad in white kimono that is decorated with a blue arrow-like motif. Around his waist he wears a blue and gold bow tie with long twin tassels, a red belt with white spots. His long, black boots have several blue buckles, cream-colored soles, and are pointy. The furry grey and dull blue boa on Kaira's shoulder extended from half of his head to half of his legs.

As a child, Kaira is briefly seem wearing a white V-neck T-shirt with dark blue markings over a long sleeved black shirt.

Kaira is said to be a "han'you", a Half-Yo-kai, who is descended from both Yo-kai and humans, and he seems to have a complex due to this.

He wields a sword with the name "Jaou Ken" (Snake King Sword).

Kaira still serves as the Yo-kai Detective Agency's ally while juggling his duties as the new Yo-kai Lord. He also plays an integral role in investigating Shutendoji's actions and locations of the Youseiken.

In SS012 Kaira saves Tomura from Shutendoji and his underlings, having monitored their actions. He then explains to the Agency about the Youseiken, stating that there were 5 of them, including Fudou Raimeiken and Ashura Gouenmaru owned by Douketsu. Knowing that Shutendoji was after all 5 of them and being the threat to the Yo-kai and Human World, Kaira tells the team the possible location of Suzaku Soutenzan.
