Well that went fast.

 for Rin's character: I'm not sure having a blind character would be beneficial to this roleplay especially since the start of the roleplay will involve a scavenger hunt per say. Also she'd need to be cut down a couple ages to around 13 to 12 which are around the average age of genin from the naruto series. My suggestion for the blindness make it so she is either near sighted (or simply bad eye sight in general) and I'll allow her bloodline some high resistance to illusion based genjutsu but some genjutsu like Cee's from the Kumokagure are light based. Having complete immunity to genjutsu is something I'm not especially comfortable with. Also note that shadow clones are a jutsu I wouldn't allow simply because they are fairly hard to make and Naruto simply was able to make them through sheer chakra levels. My guy will have a wood clone based jutsu but it is rough and it takes a lot out of him even with his extensive talent in ninjutsu. 

Also I'm a bit confused on exactly what that song based jutsu does Rin.

For both characters they need history upgrades for further reference see my character for Konoha:

(Note: They don't need to be AS big as Mitsuhide but somewhere near there)

 =========================================

Personality: Kind and (somewhat) virtuous, Mitsuhide is a very understanding boy for his age and has a fascination with nature in general finding it beautiful and loves to simply lay down and look at it for others. He is a loves the peaceful nature of the village and the area around it and normally has a bright smile on his face. Mitsuhide is very trusting towards his friends and is very hurt when he is betrayed by someone holding a grudge for a very long time. He has a faint distrust of the Uchiha Clan due to their histories during the shinobi war. However he is not trusting without reason as his family is always remembered the betrayals they've suffered and as a result this impression was forced onto a young Mitsuhide as well. Despite this however he still has a couple of friends inside the Uchiha Clan. He is very grateful of others and is always willing to repay someone's kindness and is never one to forget when someone had helped him. He loves animals and is especially fond of young dogs but most wild life also makes him curious as well be them flowers or boars. He keeps his word as often as he can and is always the first one to admit he made a mistake thinking of it as a learning experience in his excitement to grow up. While he is energetic he is not overly so and keeps a calm demeanor for the most part but when allowed to he lets his child like side of himself do what it wants. He is quick to make a friend and tries his best to help others with their down faults if they look like they are struggling. However he tries his best not to bring up personality faults. He is not one to pull pranks on others or to act out but he is somewhat sarcastic and sometimes whines a bit when he doesn't like what he hears. Despite this Mitsuhide somehow manages to be polite when the occasion rises.

History: It was during the great shinobi war when the clan Senju and the Uchiha Clans built the village Hidden in the Leafs and which came to be a very powerful village in the day to come. However before dying Hashirama settled down and produced a family that would be protected by his brother until his demise. The Senju clan has thrived and grown strong two generations later as the new heir to Hashirama Senji appeared in the form of Mitsuhide. Mitsuhide was gifted with great chakra reserves and a natural talent as well as the clan's natural ability to heal similar to that of the Uzumaki Clan but still slightly inferior in chakra and healing prowess. As a child Mitsuhide proved to be a handful, as he was always exploring and trying to see new things; even as a baby he was one to quickly figure things out or simply enjoy small things while disliking large and noisy things. He was often read to as a child by his father who helped him train when he came of age and he was taught some simple first aid by his mother on the side because of his tendency to go out and get himself hurt falling on trees. 

However something was different about this Senju boy, whom his father found to be talented in many ways, and when the time came, and by complete accident none the less, while trying out a basic jutsu he accidentally summoned some wood out of the ground leading to the boy being hailed as The Boy of the Wood Style or by some of his more fanatical family members a possible second coming of the first. He was confused about being compared to his great grand father but he liked it too, his grand father being a great hero, and all the boys various friends, whom he had a plenty of, were mixed in their feelings between being surprised and not so much as they expected many things from this Mitsuhide whom had proven himself a already capable ninja in his training exercises.

 He has often gained many friends throughout the village, but not because of any special skills or his kekkei genkai, but because of his upbeat attitude and general friendly joking nature. He is often a boy who doesn't give up and tries his hardest no matter what the task is. His drive pushes him to become stronger and better which is why he had become so skilled in ninjutsu. However he is known to have some humility despite his pride clearly willing to admit when someone is better than him, well at least when he wants to. He wasn't much of a prankster and didn't like messing things up around the village but he did enjoy making a good joke at someone's expense. While he had many expectations pushed upon him, especially with the second nickname he was called a lot less often, his drive and determination to live up to it his expectations. But he didn't show it outright as a goal and never stated it he simply said he wanted to be better for his family. He passed at near the head of his class in ninjutsu, bottom in genjutsu, and he did fair in his Taijutsu skills but despite this his reputation has become slightly overblown. While he is bombarded with expectations Mitsuhide has graduated the academy with a smile on his face and a fearsome determination in the will of fire in his heart.
