Rin Aroshio

"Even with me being blind i'm strong alltohether so dont underistamate me."

Rin was one of the main supporting characters of the series. He is a Roshin Sensei Master in the Aroshio Clan.Rin was extremely serious and mature for his age, and had great control of his emotions. Before and during the training ,and before  the spirital talk with Tsunami  he was cold, and somewhat arrogant. In his older  years, Rin  was a kinder, optimistic teen  who smiled more often.He was 14 and,had a problem of being blind.Even though his family knew he could not see they still trained him ,and he became a Roshin Sensei Master.

Personality
Rin displayed similar efforts to condescend others during his match with Susano'o who, despite being repeatedly struck down, continued to try and fight him. While Rin  tried to show Susano'o  that fate cannot be fought, and that someone who is weak will always remain weak,Susano'o was unwilling to accept this mindset, arguing that Neji, for all his belief in fate, had not accepted his own destiny.Rin's ideals and personality changed drastically due to him suffering his clan's cruelty ,  and became cold, indifferent, cruel, cynical, somewhat arrogant, unreasonable and devoted the next nine years of his life to kill ,and get revenge.

With this example of overcoming "destiny", as well as finding out the truth about his father's death soon afterwards, Rin abandoned the concept of inescapable fate. No longer bound by the idea that he was stuck at his current status, Rin  resolved to become strong enough to never again lose in a battle. To do so, he began putting more emphasis on working well with his team and started to value a mission's successful completion and his team-mates' safety over his own betterment, even encouraging himself to continue pursuing his own dream.

Plot
Rin comes from the edge building of his home.When he was young he was never trained at all ,and when he first encountered his Aunt she thought he should have been trained.He was moved to a different part of the building to be trained by his uncle.First he did not like his Aunt ,but when she started training him to find out Kiro he posseses he first did not what it meant then after they tought him he had to choose Tinkiment,Ginkiment,Ninciment .After 5 years of training  he was a swordmen ,and a Tinkiment.He also did not like how everyone  was so loyal to his brother because he was Ginkiment ,but he did not care.He challenged his brother in front of his family and told him if he wins he switch spots in roles.Everybody stopped training Rin ,and soon the battle.

He had to do something so he made a himself stronger.He made a tinkement form. Tinkomni Sukuzini form where he  just injusted in himself.He has  two powerful modes.First he looks different he is not blind in that mode ,but when hr goes back he is .The  man he was before is gone he becomes more deadly.His scales start to scatter by day so he would have to stay in that mode until it fully covers then switch back.He basically gets the power of the Tinkiment king witch is  snake powers.After being fully transformed by Snake King's DNA, a white snake extended from his navel, which he was capable of using to telepathically communicate with other snakes. He was also capable of creating other white snakes of various sizes from his body. Rin demonstrated the ability to alter the size of these snakes at will through the use of hand seals, even after they had separated from his body, and could also hide within the snakes to conceal himself. As the snakes shared the same Chrennt as Rin's himself, he was capable of using this method to hide from a user of the Ginkiment, despite its ability to see Chrennt as colours. He could also transform his entire lower body into a white snake, as well as form additional snakes to act as makeshift legs.

To counteract ginkiment that are dependent upon eye contact, Rin could instead rely solely upon his snakes' ability to perceive their surroundings through sensing the ambient temperatures and smells using their tongues, rather than his own sight. Additionally, Rin could utilise the fangs of his snakes to inject drugs into others. In the anime, he was also able to inject drugs through the snake extending from his navel, including one that could knock Susano'o  out, despite her having received treatment to be immune to poison while with Snake King. After researching the Sssoussou clan Dydreo  through Suigetsu, Rin altered it so that he could make potions into liquid by  the snake arm ability. This ability, along with's regenerative qualities, extended to the white snakes that were generated directly from his body.

After implanting King Snake's cells into his body, Rin  gained all of his snake-oriented techniques and abilities, first exhibiting some of these skills to kill several Takigakure ninja with great ease using multiple snakes. He could also use the Hidden Shadow Snake Hands and its variants for a quick ambush attack. Rin uses his clone snakes.In the anime, Rin developed clone snakes using Snake King's DNA. He could then form several of these snakes into a larger snake for offensive usage or use them to recreate life, although the latter required an extensive amount of time if not used in the right place. Another weakness was that these snakes had a short lifespan, causing the revived beings to perish in 48 hours. He could use a clone technique from snakes and also developed another breed of snakes that could absorb  Chremmt.

Kiro Vs Rin
So the battle was pretty quick as the family watched they were amazed how strong he was ,and how wrong they were wrong.He brutally beat him .He did not even get a scratch from his brother because he was not at  his paste he simply went to his Tinkomni form, to finish of but he went to his 0.5 because thats is his kind of most powerful he could be without going to his Snake King  mode.He is  mostly powerful in this mode beacause he does not like to embarres peopl infront of his family ,but it felt powerful.In this mode he is able to destroy all opponent he can sense there strength ,and take his Chemmt by not even touching them.This something not every past Tinkiment could use all the time you must be strong even if your blind.

Meeting of Dissapointment Training Arc
When he meet Tsenko he was angry .He took all the fame he killed someone he never got to meet his father.Some reason he did not like the betrayal of his family .His grandfather thought the same thing so he left .Rin followed him ,and to his despite he found some thing.He calls this the right decision ,but his family thinks he is wrong.He goes to a home in a small village but before he reaches it there was a girl.She was fighting someone she looked like she needed assistants so she helped her so they became friends ,and went to the same path.Soon they began to have a liking to each other ,and got real close to each other but h started to stay away.His grandfather decided to stop ,and live in the peaceful village they stopped by ,and it was the two of them.Soon they bumbed into another and he joined the journey and it went on.

Soon they went to the evil snake king .He said he devotes himself to the king if he gives him hiis body ,and he had to think about it.Soon he thought he gave up to his evil glare ,and was trained by the evil king.He soon started to train himself when he let the snake king king inject with evil poison that turns to something dangerous .He turned him into a monster.If  he fully transforms, Rin gains a massive power boost but loses his mind to his murderous side, signified by a change in his voice. When transforming, Rin's skin turns dark and his sclera turn black.Also he changes his hear from orange to white.. He also gains a black stripe running from the middle of his forehead and down the bridge of his nose.

Rin's abilities serve as the origin of Snake king's Ninkiment that he brands his various followers with, which were created using Rin's own bodily fluids that were then injected into the intended individual. As such, he is able to use its power to its full extent without it eroding his body. In this form, he turned his arm into a shield to defend himself and created a number of Ninkiment cannons on his back that were capable of devastating the area.

Fact
This mode was not made by his discovery he was actually injected with th poison.
