Aniki (missing-nin)

is a missing-nin.

Background
At some point in time, Aniki graduated from the academy and became a genin. But due to his nature, he would often abandon missions he didn't like, and ultimately became a missing-nin. Sometime later, he took Oppo and Teru in as his underlings.

Personality
Aniki is a rather rude and opinionated person, even towards those who help him, even going as far as beating them should they get under his skin. Aniki has a lazy and feisty personality, which caused him to not complete assigned missions during his time as a shinobi. He also likes to drink hard alcohol.

Furthermore, Aniki is quite short-tempered and cruel, threatning to harm Osaka if she didn't behave. Despite also getting hold of the Seventh Hokage's daughter, Aniki showed no fear in doing so, even going as far as to decide to sell Himawari in the black market for any of Naruto's enemies, merely in order to receive a large profit, and wasn't concerned of possibly having Naruto hunt him down for doing so.

Appearance
Aniki is a rather tall guy with short gray hair that is shaved at the temples in a zigzag pattern, making his hair look like flames. He has black eyes with deep streaks underneath and a red tattoo near his left eye. He is also missing his eyebrows and has round earrings inserted into his ears. Aniki is dressed in blue pants and black boots, as well as a white t-shirt, over which is thrown an orange jacket with fur on the collar. Around his neck hangs a golden chain with a pendant in the form of four cubes.

Abilities
As a genin, Aniki has mastered the basic skills of a shinobi. He is fairly skilled at taijutsu, fighting on par with Himawari Uzumaki, a Byakugan wielder. He is physically strong, being able to easily survive a blow from a Gentle Fist, and also has some leadership skills, being an authority for other people who follow his orders.

Ninjutsu
Aniki is proficient with the Fire Release, being able to cast extensive techniques such as Fire Release: Fire Dragon Wall by surrounding the opponent with a ring of fire. He also demonstrated the ability to bombard the enemy with small fire projectiles, and attack with a massive stream of flame. However, the strength of his fire proved rather weak as it unfazed Kawaki.

Kawaki & Himawari Academy Arc
Aniki received an order from a mysterious individual to kidnap Osuka Kamakura, but was not warned that she might not be alone. After Oppo and Teru kidnap Osuka Kamakura and Himawari Uzumaki, Aniki arrives at the warehouse where they were being held and remarks that his assistants took Himawari for nothing, as they only want Osuka's ransom. He beats the assistants, and then says that you can get a lot of money if you sell the Hokage's daughter. Aniki then leaves, but returns when Oppo and Teru tell the kidnapped girls about their leader. He blows up one of the storage crates with Fire Release and forbids anyone to talk about him.

Later, when it was already dark and Oppo and Teru were asleep, Aniki was sitting on a box near the exit drinking alcohol. Himawari manages to get rid of the ropes she was tied with and attacks the kidnapper. Aniki successfully confronts her, and then defeats and strangles Himawari, despite Osuka's requests, promising to kill her afterward. However, thanks to the engineering that Neon Asakusa owns, Kawaki arrives in time and rescues the girls. Aniki enters the battle with him, but due to the fact that Kawaki is stronger, he loses to him in a matter of minutes. After he is arrested, he notices that Himawari ruined everything.
