Appearance:
5-10 years - Tsubasa is a bit tall for his age, being around 112 cm (3'6) at the age of 5 and 141 cm (4'6) at the age of 10. He has blond, almost silvery, hair that is distinctively messy, no matter what he does. It usually hangs in his face, so he clips his bangs back to the right with light blue hair clips that were once his mother's.

Nice, he has a typical kid look to him and his hair is easy to imagine.

From age 5-10, Tsubasa has a skinny figure, which as he grows, starts to gain muscles from during heavy-lifting and walking around a lot with his father, who is a merchant that travels around. He has fair, peach skin with freckles on his nose and back, and pale blue eyes. He usually wears dark gray shorts with many pockets, a tight black t-shirt and thick, black gloves to pick things up. He also wears gray shinobi sandals. He has his blue hairclips, a black wired necklace with a simple gray ring on it, and blue elastic around his right wrist as accessories.

Oh his outfit is nice and something a kid would wear. It gives a kid vibe but also the vibe of being a character you shouldn't forget.

10-15 years - Tsubasa is around 144 cm (4'7) before he turns 11 years old, and is around 174 cm (5'7) when he turns 15 years old. His hair has gotten a bit darker, but is still relatively light, and he has it down to his shoulders so he usually ties it up in a low ponytail with a light blue elastic which was once around his wrist. He also still pulls his bangs back with his hair clips to the right. Due to traveling, Tsubasa's skin became a bit darker, so he now has a bit of tan, but not much. His freckles are a bit lighter, but still visible if looked at close enough. He gained more muscles, becoming a bit bulkier but it is mostly his legs that are muscled, his upper body seems to be a bit lean. He wears the necklace, the blue clips, blue elastic, and now has a pierced earring on his left helix (ear), which is a metal loop (reference; Shikamaru). He wears a black mesh shirt with a sleeveless dark gray hoodie over it, baggy black pants and dark blue shinobi sandals. He still has the thick, black gloves, and he also has a pouch attached to the back of his pants.

A lot and goes into amazing detail. The way his body change due to his training, how he changes up what he wears and the effect of the training clearly shows in this part. Nice.

Around the age of 14, he carries a black with royal blue intricate markings sheathed sword (around 74 cm) on his waist. The weapon itself has royal blue hilt with a golden wired string wrapped around it, and the blade is a single edged blade with a silver coating.

Oh cool, that sounds cool and in my head looks like a great looking sword.

15-23 years - Tsubasa is around 176 cm (5'8 ft) before he turns 16, and is around 180 cm (5'9) when he is 20. His hair now reaches to his thoracic (middle back), tied in a skinny braid or low ponytail when he's lazy. He has bangs that frame his face, and bangs on his forehead that sweeps to the right, hovering over his right eye. He sometimes uses the blue clips to keep them out of his face, but nowadays he leaves it as it is and has the blue clips on the left side or clipped to his to the scarf wrapped around his waist. Tsubasa still has fair tanned skin and freckles (which now cover a bit of his shoulders), and has become a lot more muscular in the torso and arms. Tsubasa wears white pants with a two black lines down the sides, bandages covering the top of them, and a black sleeveless shirt that is tight around his torso. A dark blue scarf with intricate purple designs is wrapped around his waist. He has black knee-high steel-toed shinobi sandals, with two royal blue rings covering the top and bottom of them. He wears a black, baggy sleeve cloak over his clothes, which he ties around his knee with two royal blue wired strings. He still has a sword attached to his waist, but it is now around 75.8 cm in length. The scabbard for the sword is black with royal blue kanji on the sides. On the right, it says '悪魔を克服する' (Overcome The Demons; Google Translate) while the left says '内から征服する' ([And] Conquer from Within, Google Translate). The chape and the locket of the scabbard are both royal blue, and has the black wired necklace on the scabbard, acting as the hanging cord of the scabbard. The weapon itself has a royal blue hilt with a golden dragon wrapped around the handle, its eyes a bright ruby red gem, it's head being the pommel of the blade, and a golden wired string wrapped around below the guard. The guard is the two tails of the dragon, having spikes on the top of them. The blade collar is a royal blue color. The blade is a single edged blade with silver coating, and the edge pattern is ragged edges from after the blade collar to the edge and from there, smooth from the edge to the point of the blade. He has kunais and shurikens hidden inside his clothes, and has a sheathed dagger attached to his right arm. The sheath for the dagger is just blank with gray lining, and the dagger is normal, having a black hilt and a ragged blade which was black with a silver edge. He still has his left helix pierced, but now instead of a metal loop, has a dragon curving alongside the helix to the orbital, the head of the metal dragon being the piercing (which is where the helix is).

His outfit, his appearance, and his weapon is all in amazing detail. It would be hard not to imagine how it looks. If someone wanted to draw him from this description alone it would be perfect. I also love all the detail and you can tell he grew from his earlier stages.

Personality:
5-10 Years - Tsubasa, around this age range, is playful/teasing/sarcastic, and is known to sometimes prank his father, Hibiki. He becomes a bit mature around the age of 7, where while still holds his teasing and sarcastic manner, he isn't as playful, instead focusing on helping his ill father with the mercenary work, and teaching himself to be a shinobi with books they get from different villages to protect his father. At the age of ten, Tsubasa is seen as calm, intelligent, and is sarcastic to people he befriends or is close to (ex; his father). He is hard-working and sometimes overworks himself throughout the whole night, passing out from exhaustion and overexertion. Since they travel around a lot, Tsubasa is socially awkward around new people, preferring to stay silent, and tends to stumble over his words when he does (especially at the age of ten when he has to talk to customers while his father is resting).

This is great. It shows how he changes up to age 10. It also shows how the constant traveling affects him in more ways than just his appearance. Great job.

10-15 Years - Tsubasa, used to talking now, can now talk to strangers and customers easily, even having a nice conversation with them or bargaining with them about the prices of their products. He is calm, intelligent, and is still sarcastic, and became quite blunt with his words, being brutally honest to people. Since he doesn't have any friends from traveling with his now mercenary work after his father's passing from the illness, Tsubasa doesn't trust easily, or is stubborn to not trust or grow close to anyone at all. Around this age range, something happens to Tsubasa, giving him survivor's guilt and depression. Tsubasa is prone to losing motivation with the mercenary work, making him stop in the middle of the road with the cart and just stay there for 2 weeks or a month until someone kicks him off.

Nice, the way he changes as he gets older and how he acts around strangers because he has no one else with him shows what happened to him. Now that he is alone and doesn't trust which is a great quality. Great job.

15-23 Years - This is the worst year for Tsubasa. Because of his depression and survivor's guilt, he becomes a smoker and now lives in Konohagakure, where he sells products from the mercenary cart he once had but sold. Tsubasa still trains in the ninja arts, but because of these mental illnesses, he loses motivation and stays home curled in bed doing nothing.

Oh, the stress Tsubasa is having took a negative turn and made him a smoker. Great job showing what stress and depression can do to a person. It brings character to him.

Around the age of 17, Tsubasa slowly gets better and becomes he who once was, and even becomes a shinobi of Konoha, starting off a genin at the age of 17, chunin half year later, then jounin at the age of 18. With the permission of the Third Hokage, Tsubasa now travels around for 5 months with his new mercenary business to sell products before coming back to Konohagakure.

Oh ok so he was a pretty old genin but thanks to experience before hand he can move up in ranks faster than a genin fresh out the academy. Nice.

Tsubasa sometimes is a special guest to the Shinobi Academy to share his story with depression and survival guilt's, and how to overcome them. He is hard-working, calm, intelligent, and he is once again sarcastic and teasing, like he once was when he was child. He still has trouble connecting with people, and people find him off putting because of his bluntness and sarcastic words (ex; "ugh, I just want to kill myself.."). He also learned to not overwork himself.

Oh ok, I like how you have him share his story with the class like how schools have drug addicts share their story. Also it's great to see he still holds that little childlikeness to him from many years ago.

Abilities:
Primary Release - Water
Secondary Release - Lightning

Oh nice

5-10 Years - Around this age, Tsubasa is just a child, so he doesn't have any battling experience until at the age of 7. He is only capable of carrying large logs at a time, and he has high stamina from traveling around a lot with his father.

Great job. It's great to see that he isn't fighting like Kakashi at age 5. It is also good to see he is getting stamina from the traveling.

10-15 Years - Around this age, Tsubasa starts training, teaching himself with books to help become a shinobi to protect his father. At the age of 15, Tsubasa is around high level chunin with his physical prowess, low level chunin with his ninjutsu, high level genin with his genjutsu, and low level chunin with his kenjutsu. His chakra is around low level chunin.

Nice It is also a great age for him to realize his strengths. His stats also fit him greatly.

The ninjutsu he knows are as follow; Water Release: Water Whip, Water Release: Water Gun, Water Release: Water Shield, Water Release: Water Shuriken, Water Release: Water Formation Wall, Water Release: Water Bullet Technique.

Oh so for now he only knows water. That's good and it's great he's learning all these water based jutsus at this age and skill, it's to be expected.

15-23 Years - Tsubasa now his high jounin physical prowess, low level jounin ninjutsu, high level chunin with his genjutsu, and high level jounin with his kenjutsu. His chakra level is around high level chunin, but is seen as low level jounin because of his great control over it.

Nice, a 23 year old I would also think he would have slightly higher stats but given his background and how he trained I can see why they are what they are.

The ninjutsu he knows are as follow; Water Release: Water Blade Technique, Water Release: Water Dragon Whip, Water Release: Water Beast, Water Release: Water Whip, Water Release: Water Gun, Water Release: Water Shield, Water Release: Water Shuriken, Water Release: Water Formation Wall, Water Release: Water Bullet Technique, Water Release: Water Spirit Wave, Water Clone Technique, Shadow Clone Jutsu, Water Release Genjutsu: Demonic Phantom Fog Prison, Water Prison Technique, Water Release: Water-Heavens Convergence, Water Release: Great Waterfall Technique, Hiding in Mist Technique, Water Release: Water Dragon Bullet Technique, Water Release: Water Fang Bullet, Lightning Burial: Banquet of Lightning, Lightning Release: Electromagnetic Murder, Lightning Release: Snake Thunder, Lightning Release: Spider Web, Lightning Release: Thunderbolt, Lightning Water Dragon Bullet. Tsubasa created three new ninjutsus then, one named Water Release: Spiraling Water Jet, which is where Tsubasa coats himself in water and moves through the air like a waterjet, making this a physical attack. The second one is Lightning Release: Dragon Fang, where he generates lightning in the form of small dragon with large fangs. Once the dragon bites the opponent, they get electrocuted where the jutsu then explodes. The last one is Lightning Water Jet, where Tsubasa uses his water jet technique then coats it with lightning for a more devastating affect.

This is great. All the jutsus he knows are all either water or lightening except for a genjutsu which is amazing. I like how you worked one in there. Great job he has a lot of moves in his arsenal.

Back Story:
Tsubasa was born from Kita Ayame and Kita Hibiki, where his mother died from complications during birth. His mother was once a shinobi of Kirigakure, but was forced to retire after a severe injury to her spine, leaving her unable to walk. Hibiki then took care of Tsubasa, staying in Kirigakure for a year before leaving to continue his mercenary business, taking some of Ayame's books she studied about for shinobi arts, her hair clips, necklace, a picture of them all before she passed and hair elastic for Tsubasa later on.

I like how this is how Tsubasa starts training from books that belonged to his mother. Also how he has a picture of his mother with him before he and his father left.

At the age of 3 years old, Tsubasa was given these items when they were visiting a village in the Land of Iron, making Tsubasa desire to grow his hair out for his mother just so he could use the hair elastic, which he had around his wrist. He already began using the hair clips, even though he barely had bangs at the time, and wore the necklace constantly. He had the picture of her in a pocket of his for years until he finally framed it years later.

Nice, I like how he wanted to to grow out his hair for his mother. I also like how he has already started using the objects he was given. The sentimental value of all the items he has shows he cares and loves his mother.

When he was at the age of 5 years old, Hibiki gained a disease when they were in Otogakure, leaving him only 5 years left to live before passing. Because of that, Tsubasa forced himself to grow up faster and become mature so he could help his ill father, even overworking himself sometimes just to help.

Tsubasa's reaction is realistic when wanting to protect and help the person you love, it would make you do anything, which includes the overworking. Also seeing that he force himself to grow up because of his father about to pass is a lot of stress for a child, but it has to be done. It shows that Tsubasa is mature to even think of that idea to start with.

At the age of 7, Tsubasa decides to learn shinobi arts to protect his father after they were attacked by bandits on the road, who stole most of the money they had.

So that is when he decided to take his ninja training seriously. That event would make someone want to learn how to defend themselves to make sure that doesn't happen again.

At the age of 9, Tsubasa had to try and communicate with customers as his father was bedridden, only becoming a good socialist at the age of 11, after his father passed away in the Land of Wind.

So he even worked on his people skills so he can keep the shop open. It does show that Tsubasa is very mature and does what he has too.

At the age of 13, Tsubasa lived in small village in between the Land of Wind and Land of Fire, and he stayed there while training in the shinobi arts, and where he gained his sword from the village chief. This village was attacked by a group of bandits which had two A-ranks shinobis, and because of that, Tsubasa watched as the entire village was burned to the ground, forced to watch some of his friends die, and watch as even the babies were killed by the group, as he was not entirely strong enough against two a-rank shinobis. This caused survivor's guilt and depression for him, feeling that it was his fault the village died, and wished that he died as well with them, as he now has nothing.

So he finally gets something and its stripped away. This would definitely make someone go into a depressive state. It would also make people feel like the world is against them right now.

He goes to Konoha when he is 16 years old, selling his cart there to buy an apartment and where he starts to smoke, not resorting to drinking as that was what caused complications during his birth and ultimately killed his mother. It was also suspected it was what caused the disease to his father, though it could not be proven because they didn't have the skills or technology for it. There, he meets Itachi and Shisui, both who helps him with his depression and survivor's guilt, making him slowly come out of his shell until finally, he starts trying to become better at the age of 17.

Oh so this OC actually does interact with the canon characters. Nice, I been waiting for this. It is also good to see that you used smoking to ease his stress and depression like how how some people do in the real world. It brings some reality to him.

Though, he gets dragged back under after the Uchiha Massacre, he forces himself to get better for Shisui, who he secretly loved at the time but now could never tell because of his death. Because of this, Tsubasa befriended Kakashi, Kurenai, Asuma, Gai, Naruto, and Sasuke, where he viewed Naruto and Sasuke as little brothers. He loved them dearly and trained hard to protect them, and even went to their academy to show his story so the two would know not to ever feel alone and to help others in case they are going or will ever go through what he did.

So the massacre strips him from his friends again so he returns to his former self. Nice, I also like how you showed his love for Shisui by making him get better for him after his death. Good job.

At the age of 23, Tsubasa was killed during a S rank mission protecting one of his teammates, who he had told to go ahead to Konoha with the scroll that they had went to get in Kumogakure. No one knows who attacked them, but it was ANBU Root. The teammates he saved were Hana Aiko, Itou Kisaki, and Kimura Ryuuto. The reason for ANBU Root attacking them was because of the scroll, which Danzo wanted, as it held secrets that he could exploit. Tsubasa died as a hero to his teammates and village, where his name was put on the Memorial Stone. The result of his death made Naruto and Sasuke, who was once friends because of Tsubasa, push each other away and become the rivals they are now, and make Kakashi's survivor's guilt (which I believe he has and is caused by the deaths of his team) a bit worse.

Whoa so his demise is at the hands of others to protect a teammate. Good, he does deserve to be called a hero from sacrificing himself to save his village and his team. Also it was great to see that Sasuke and Naruto still became rivals afterwards and the story continues from there. Good job.

Relationship with Canon Characters:

Uchiha Itachi - Itachi and his cousin, Uchiha Shisui, became friends with Tsubasa after Shisui spotted Tsubasa at a training ground, trying to practice a technique he was trying to learn. Shisui helped Tsubasa out, and Itachi even pointed out some chakra control problems in Tsubasa's system which was causing the technique to fail. After that, the three regularly met up for training, until Tsubasa's depression and survivor's guilt caused him to stop. This made Itachi and Shisui worried and after learning what happened, the two worked together with Tsubasa and helped him work to getting better. After the death of Shisui and the Uchiha Massacre, Tsubasa has mixed emotions for Itachi, as he hates him for what he has done, but still adores him because he and Shisui helped him to get better. Though, Tsubasa had a bit of a suspicion that Itachi was ordered, as Shisui once slipped up about the coup de'tat when he was ranting to him one night.

Oh his relationship with Itachi is nice. I also like how you have the mixed emotions instead of complete hatred.

Uchiha Shisui - Shisui, and his cousin, Itachi, became friends with Tsubasa after Shisui spotted Tsubasa at a training ground,  trying to practice a technique he was trying to learn. Shisui helped Tsubasa out, and Itachi even pointed out some chakra control problems in Tsubasa's system which was causing the technique to fail. After that, the three regularly met up for training, until Tsubasa's depression and survivor's guilt caused him to stop. This made Shisui and Itachi worried and after learning what happened, the two worked together with Tsubasa and helped him work to getting better. After some time, Tsubasa gained feelings for Shisui, loving him secretly. Tsubasa believed Shisui wouldn't love him, since Tsubasa saw Shisui flirt with females and always complain why he can't have a girlfriend. In reality, Shisui was actually bisexual, but because of stigma or homophobia, especially in the Uchiha clan, Shisui kept quiet about it, and loved Tsubasa in return. In the end, the two would never know for their feelings for each other, as Shisui then committed suicide.

Wow, that is a great love story that is better than twilight. But everything is better than twilight so I'll just go ahead and say that it was great seeing how they kept it secret because of their fears and not knowing how each other would take it till it was too late.

Hatake Kakashi - Kakashi and Tsubasa met each other when Kakashi checked out Tsubasa's Shinobi Gear Shop, and after seeing how well knowledgeable Tsubasa was, Kakashi decided to visit the shop more often for gear instead of others, causing the two to become friends, even close as brothers.

Oh, so Kakashi met him first as a clerk instead of a ninja. Cool it makes the relationship a little more interesting.

Yuhi Kurenai - The two met when they were to go on a mission together as chunins, and they became fast friends on the mission because of their mutual love for evening drinks.

It's great seeing them bond from the things they have in common and how they met on a mission. It brings the ninja aspect into this.

Sarutobi Asuma - The two met through Kurenai, and because of Tsubasa's smoking, Asuma and him became good friends, but they only spend time smoking and not talking together.

Oh so it's not a actual friendship but it is a friendship. Cool

Might Gai - The two train together sometimes when Tsubasa isn't busy, so they are kind of friends.

Training buddies. That is perfect for Might Gai.

Uzumaki Naruto - Tsubasa met Naruto when the boy tried to steal something from his shop, and from there, they became friends and then brothers.

So the way Naruto is was how they met. That's a cute and fun way of meeting the main character.

Uchiha Sasuke - These two met through Itachi and Shisui, and Sasuke at first hated Tsubasa as it meant not having any time with Itachi, but after a few months, Sasuke warmed up to Tsubasa and seen him as another brother.

Oh so the way Kid Sasuke was about Itachi caused this feeling jealously but after some time, warmed up to the idea of him. Cool.

Other:
This is just for fun, so I don't think I'll be writing a story for him. Maybe, who knows. Tsubasa is pansexual, which means he loves any and all genders. He also used to self-harm at the age of 14, but forced himself to stop before it could become worse. That's all.

He should be in a fanfic in fact, I hope you do put him in a fanfic. Not as a side but as the main character. He would make a different and new type of character to read about.

_________________________________________

Final Analysis- This OC is great and has nothing to work on. He has a great background with amazing detail in his relationship, appearances, personality, and his moves. He is a very unique character and you should definitely make a fanfic about him. He would be really popular and would be loved. He is one of the most thought out OCs I have seen and I can tell you really worked hard on him. You did a amazing job. It was a honor reviewing him and I hope you consider the idea of making him his own story. Thanks for choosing me to review your OC.
