Kayui (カユイ, Kayui) is a shinobi of Kumogakure.
Kayui is a relatively calm and level-headed individual as seen from when he calmly questioned what they should do when they were being pursued by Ameyuri. He later attempted to keep the peace between his comrades when a conflict arose.
Kayui is a tall, dark-skinned shinobi of muscular build with shoulder-length slick-backed blond hair and purple, pupiless eyes. He wears the standard attire of the Kumogakure shinobi, and wears his shirt zipped down midway.
He is skilled in laying traps as he helped his comrades Yurui and Nurui creating a clever trap, using the preexisting environment and Earth Release. He is also very durable, able to survive a Lightning Release attack by Ameyuri Ringo.
Shinobi World War Arc
Kayui and the surviving members of Yurui's unit regrouped and the de-facto leader Nurui decided that they should flee from Ameyuri Ringo. Though Omoi was against this and an argument ensued as they fled, Kayui attempted to keep the peace between the two. Later when Omoi went to confront Ameyuri, Kayui and Nurui returned with him and were incapacitated by her attack. When the rest of the Third Division arrived and Ameyuri was sealed in the marsh trap they had prepared, Kayui departed with the other members.
- Kayui (痒い, Kayui) literally means "itching" or "itchy".
