Akkun

is an Akuta.

Personality
Akkun is unique among the Akuta. It has very little aggressive tendencies. More akin to a child, it is shown to be playful and curious at the world around it. It has also shown a strong attachment to Inojin Yamanaka, possibly imprinting on him as a surrogate parent, as it likes to remain around Inojin as much as possible. It however is nervous at meeting other beings and is prone to lash out. Akkun is shown to have a measure of sentient intelligence, as it is very particular on how it is referred to and is capable of talking and learning names, provided they aren't too difficult.

Appearance
Akkun is an imperfect Akuta. Unlike the other Akuta which very large in stature, Akkun is very small, roughly the size of a house pet. Its body is comprised of loose dirt with no features beyond a round body with simply arms and legs, the left arm of which is noticeably longer. Its face is a white owl-like mask with a cracked left eye-hole and big red eye in the other hole.

Mitsuki's Disappearance Arc
After some of the Akuta were destroyed, one of them imperfectly reformed. Soon afterwards, it was found by Inojin, who it immediately came to like and persistently followed around. Inojin's friends felt that should bring it along as proof to Konohagakure of their discovery of a conspiracy in Iwagakure. After it was decided to go get help from the Ōnoki, Inojin was chosen to stay back with the Akuta as it would draw too much attention. During which, Inojin began warming up to the odd creature. Soon realising that it hated being called simply an "Akuta", Inojin came up with a variety of names to see which one it would like, ultimately choosing "Akkun", much to its joy. Inojin began attempting to teach it his friends names, but only could refer to them in silly nicknames. Аккун
