Character Profile
Note- This profile is going to undergo a lot of changes, please be patient while they take effect. Thanks!
Name: Nagi Shibasaburo (Pronounced Na-jii)
Age: Unknown but in Soul Society standards is quite young for he was only dead for 2 and a half years.
Gender: Male
Skin Color / Race: Pale white Caucasian/ English/ Japanese decent
Physical Description:

Nagi is tall, slim built and very pale skinned. His right arm is now missing as the result of the final battle with buru. His standard black shinigami uniform is modified to look more like a shinto-priest robe with the slits on the upper arms. His white captain's haori was also modified a bit for it includes a hood like that of a sorcerer. Special accessories include a pair of arm guards and choker that protects him from cuts and minor burns (made from Kevlar). He also wears glasses (later reveals that they are transition lenses that where made specially for him due to his lack of vision in bright lights) but usually hides them while others are around.
There are two tattoos on his face under his eyes and a small pair of wings tattooed on his back that he does not remember getting (it is suggested the the dark lines represent the fact that his nightmares kept him awake and he finally died after falling asleep). Sometimes his right eye will turn black (dilated) while the left stays blue. This state is where he earns his nickname "Two-tone". (This is explained more in the profile)
Zanpaku-to: Name- Tenchi-Kyougai (Creed of the Angels)- Stays in the form as a normal Bamboo Shinai because of the fact that he has no desire to kill. He feels strongly tied to it and gets nervous when it is removed from his grasp. He's good at fighting with it in this form since he'd trained with it for so long.

Shikai:Commands- "Protect" and "Disperse"
When Nagi uses the command "Protect" the weapon transforms into a giant white feather shaped blade used for defense only since his darker half is the spirit that resides in the Zanpaku-to at the time. This form cannot be used unless he is defending somebody(this includes himself).
When Nagi uses the command "Disperse" this is when his Zanpaku-to takes the form as a pair of white feathered wings and a halo of barbed wire appears over his head after spilling his first drop of blood in battle. Each feather being a single blade, he can control them individually as well as fly. Nagi will only use this when his darker half takes over and his urge to kill is present while the lighter side of his soul is now in his Zanpaku-to. This form is used for attacking.
Note- Nagi is starting to learn how to combine these two attributes now that he is starting to understand the spirit inside his weapon. Combined, this weapon and his abilities can be devastating. (This is when he goes "Two-tone".)

Special Zampaku-to Attacks:
Shield Form: Haro-shougeki- (Halo Crash) Uses the shield combined with Nagi’s speed and Tenchi’s spiritual energy with the force of a battering ram, sending his opponents flying.
Attack Form: Sakurifaisu- (Ultimate Sacrifice) The feathers from his wings disperse and wildly slashes at everything within 20 meters of him, including himself. Both Nagi and Tenchi completely use up their spirit energy to use this so it is only needed in desperate situations.
Bankai: Bankai:Haro-kuromeru (black halo) Command: "Repent"- Nagi's wings turn black and tattered while a long whip made of three braided strands of razor wire emerges from the empty hilt. Although this may appear to be not a very big deal to some, the power that Nagi possesses when in this state is somewhat remarkable considering that despite Nagi's kind nature, it is malicious in many ways. When his Bankai is activated, he can dive deep into the heart of his opponent, revealing the enemy's fears, all the evil deeds that have been committed, and hear the screaming and agony of every person they've ever slain, casting the individual into a personal hell. It is as if the enemy is thrown into a terrifying nightmare that is difficult to awaken from. Depending on how much evil is inside the individual's heart, the effects may vary, however, if the enemy has killed many people, then he shall be tortured by many people's crying souls. The more fear that the enemy feels, Tenchi's spiritual energy will increase due to the fact that his main power is fueled by fear. Although this nighmare is just an illusion, it distracts the opponent, giving Nagi the opportunity to lash out and eventually cause the person to bleed to death from the razor wire. Nagi will not activate his Bankai unless he is truly angered and he also has to be two-tone for it to work properly. He may possibly be able to use it, but has not come under the right circumstances for it to become revealed. (image is not complete)
Personality:His blue eyes indicate the "lighter half" for he is always seen with a friendly smile or grin. As a captain, he is extremely calm and laid back due to his belief that kido users should maintain their thoughts and emotions to help them focus better. His thoughts seem to always be focused on what is positive for he has a very optimistic way of looking at things and is a lover of good humor. It is because his belief that there is good in everyone he may be seen as naive to most people, but it is because of that belief that his is very understanding of how other people think. Though he is quick physically and mentally, Nagi is extremely clumsy and wishes to get over it along with his terrible long and short term memory. He also dislikes formality for it makes him nervous and doesn't see it as necessary in most occasions. Since Nagi has only been in the soul society for a short time, he's considered to be quite young amongst the other soul reapers and it doesn't help when he can't remember ever growing up. Despite this, he is mature and prefers calm reasoning over assertive force, but is still shy toward women. He shows no sign of restlessness nor shows any interest in excelling his power without a reasonable cause.
Due to one of his newly discovered pet peeves- Nagi will also automatically tell you how to pronounce his name upon introduction or will correct those who say his name.
[Left hand dominant- Has quicker reflexes and is physically stronger than the right.]
When his eyes go black (dilated pupils) , he appears frightening to some due to the fact that he bares a nonchalant, blank look on his face and doesn’t seem to care about anything because he lacks most emotions. This is the dark half when it comes fourth (usually by force). He may also become cocky and analytical while fighting others and will be most certain to sarcastically point out the faults of others on the intent of making them feel stupid. "Tenchi" is no different than "Nagi" when it comes to defending those he cares for but is more aggressive about it due to the fact that he will find any reason to deny his own supposable, non-existent emotions. Everything that Nagi had supposedly forgotten, Tenchi knows and is therefore the wiser and most experienced of the two. He often gives Nagi advice whenever he's confused.
[Right hand dominant- Can control spirit energy as well as perform kidos better and more accurately.]
Extra:

Abilities:
Shun-po- Arrived with the ability though was very clumsy. Mastered it during his membership in 2nd division.
Utsusemi - The ability to shun-po and leave behind an afterimage.
Instant war cry- A technique that combines hand to hand fighting with kido. Learned with Yuki.
Has very good vision in the dark, but unfortunately has poorer vision in the light. Nagi also has a high pain tolerance and will fight until his body wont let him anymore. His desire to protect and sensing his opponent's fear (as Tenchi) increases this ability.
Nagi is book smart in all forms of Kido though he prefers not to use some of the higher level hados due to their harmful power. Though Nagi is usually left handed, his right serves better when it comes to channeling and controlling spirit energy. Because of his ability to focus as “two-tone” he can control and summon large amounts of spirit energy at one time.
Best Performed Kidos:
Mirror Door (Kyōmon) — It creates a glass-like barrier which is difficult to break from the outside, but quite simple to break from the inside. (Nagi enjoys this one because his opponent cant see it- usually funny results)
White Lightning (Byakurai) — Fires a concentrated bolt of lightning from the caster's forefinger. (The only Hado Nagi prefers to use)
White Crawl (Hakufuku)- Renders a target unconscious. (has trouble with this one and will sometimes accidentally do it to himself. He mentally performs this spell by looking into the eyes of his opponent. )
Six Rods Prison of Light (Rikujōkōrō) — Summons six thin, but wide, beams of light that slam into a target's midsection, holding them in place. (Nagi will use this one if he truly deems his opponent as a threat.)
81. Splitting Void (danku) — Creates an energy barrier in the form of a rectangular wall. According to Byakuya, it is capable of stopping destructive spells up to #89.
