Sekiei

is an artificial human, hailing from Iwagakure.

Appearance
Sekiei is a young man with brown, bowl-cut hair and pale skin. He has large, green, pupilless eyes and the lower half of his face is concealed by bandages. He wears a purple tunic over a black bodysuit, his hands also being covered by bandages.

Personality
Apparently an artificial human like the Akuta, Sekiei is a very childish individual. He shows a very light-hearted nature, as he enjoys drawing randomly and is very open with his thoughts. He is very fascinated by the emotional natural and group interactions of human beings.

Abilities
Sekiei has the Explosion Release kekkei genkai, allowing him simultaneously use earth and lightning chakra natures — to give his chakra explosive qualities such as butterfly-like or centipede-like constructs.

Mitsuki Arc
Sekiei first appears at the entrance to Konohagakure, supporting Kokuyō as he attacks Saō and Uō. He leaves both men incapacitated before fleeing with Mitsuki. When the genjutsu on Yurito was broken, Sekiei's C1 detonated in an attempt to kill him, but Yurito survived, though was left in a critical condition. On their way back to the Land of Earth, Sekiei took an open liking towards Mitsuki as an artificial human. He began talking about how Mitsuki's being would help in advancing their goal, only to be interrupted by Kokuyō, who didn't trust Mitsuki with such information. As they approached the Land of Stone's boarder, Kokuyō noticed that they were being pursued by Konoha-nin. Sekiei was sent ahead with Mitsuki while Kokuyō engaged the pursuers.
