Just let me know if anything needs to be changed, here's the first draft of my character.

Appearance: Standing at 5'10" but with broad shoulders and still-growing muscle, Seiji's a young man right in the middle of his growing phase. His black hair is cut short and parted in the front, slight bangs framing his face. His eyes are a gray-blue hue that reminds one of polished steel. He wears a long sleeved black shirt under the traditional short sleeved white jacket of the Marines, which is left unbuttoned at the front and the blue neckerchief is instead tied around his right bicep. His Marine cap is turned backwards on his head most of the time, unless he needs to block something from getting in his eyes. Instead of full length pants he wears shorts hemmed slightly below the knee, and his black boots are only half-shin high. At first glance, a seemingly undisciplined recruit--but his personality and actions leave no doubt as to his passion.

Name: Seiji Shirogane

Gender: Male

Nicknames/Aliases: Not earned yet.

Epithet: N/A

Age: 16

Hometown: South Blue, Karate Island

Marine Rank: Seaman First Class

Role: Junior Officer - After completing basic training and a few simple assignments, low ranked Marines would of course need to learn from a real crew. Thus, Seiji has been assigned to his current crew with the intent of continuing his training and putting him to work in the field.

Abilities & Skills: 
Fighting Style - Seiji's fighting style incorporates basic Marine-style martial arts, a few tidbits of other styles taught on his home island, and a brawling disposition. He is best described as an "in-fighter," closing his distance with an opponent before planting his feet and slugging it out.

Rokushiki - A style of martial arts consisting of superhuman training and techniques, normally taught only to CP9 or higher ranking Marines. Seiji learned a small amount of it from his grandfather, but currently is only capable of performing one of the six techniques.
1) Tekkai: Hardens the users' muscles to the level of iron, in order to nullify damage taken from attacks. However, it can be broken by strong enough forces. It can also be used to increase the power of an attack, but because it makes the user incapable of moving, they have to use Tekkai after they have already begun their movement, thus fully commiting to that action.

Equipment: None

Personality: Seiji is devoted to the idea of being "a true Hero," and thus seeks to do good to the best of his ability. He tries to be nice even to people he doesn't like, but has little mercy for those he sees as "true Evil." However, to be considered truly evil in Seiji's eyes is a rare thing. He is still young and naive about the ways of the world, and believes that people can change if given the chance. He is also a stickler for "the Law," and seeks to punish anyone who breaks it with a fair and equal sentence. But the surest way to invoke his rage is to have him catch you breaking the law red-handed. At that point, no court, trial, or jury is necessary; Seiji will become "Justice" himself.

While not fond of the idea of hurting people for no reason, Seiji is also eager to test himself and improve his skills, and thus he is fond of fighting and other physical tests of strength and ability. He is also a hard worker, eagerly training on his own and jumping to almost any task given by a superior.

Biography: Seiji's grandfather, Gintarou Shirogane, was once a Vice Admiral of the Marines known as the "Platinum Fist." Said to embody the true essence of what it meant to be a Marine, he defeated and captured not only pirates, but all sorts of criminals, and the sea routes his ship patrolled were known as safe waters even in the vicious territories of the Grand Line. However, when his own son (later to be Seiji's father) expressed wanting to enlist in the Marines, Gintarou expressly forbade him from doing so for unknown reasons. In his old age Gintarou retired to his home on Karate Island in the South Blue, and spent more time with his family, especially doting on his grandson. Yet Seiji, too, when he became older desired to emulate his grandfather and join the Marines. Again Gintarou forbid it...but Seiji had inheirited his iron will, and would not be swayed from "the path of Justice."

Eventually Gintarou gave in, and told Seiji that if he could defeat all the different dojos on Karate Island, that he would train him to become a Marine. Though it took a whole year--no, that is to say, it somehow only took a year--Seiji accomplished the task. He'd been beaten to a pulp many times along the way, but quoted his grandfather's old saying: 

"To be a Marine is to have an iron will, an iron fist, and an iron heart."

Some time after that Seiji entered the ranks of the Marines, and through a combination of hard training and catching the eyes of superior officers as a descendant of the "Platinum Fist," was promoted from a recruit to Seaman First Class. Soon after, he was assigned to a crew, and set out to sea...
