Codename:
Age: 17/711
Birthday:
Height: 6'2"
Weight:
Eyes: Brown
Hair: Black
Relatives:
Base of Operations: Japan
Skills:
Due to his training with the kenku, Hajime is one of the greatest swordsmen and martial artists on Earth. He technically knows dozens of styles of swordsmanship, and several martial arts forms, but has had them taught to him combined to form one extremely versatile style.
He is also trained in the arts a samurai was expected to be able to perform: he can write haiku, paint, ride a horse, fire a bow, handle a falcon, handle himself with courtly manners, plays two instruments, can tell a story, survive in the wild and mix tea.

Weapons:
Hajime possesses his family katana, one of the legendary Masmune blades.

Powers:
Between the rigorous discipline of the kenku, learning spiritual focus and meditation, and an etreme amount of experience for his apparent age, Hajime possesses a nearly inhuman degree of willpower, and is highly resistant to mind control and other types of influence. Through this same discipline, he is capable of pushing himself to extremes, such as remaining conscious when badly injured, and continuing to act when he should be incapacitated by pain.

Also thanks to the kenku, he knows the speech of corvids. He cannot control ravens and crows, but he can understand them and speak to them, and corvids tend to be very well disposed towards him.
He normally has a raven named Karasu accompanying him that will sometimes act as a scout, extra pair of eyes, etc. for him in exchange for food and shiny baubles, but is not under any kind of compulsion and may wander off at times or get distracted.
History:
Kazuhiro Hajime was born in the Sagami province of Japan in 1299 to a wealthy family. His father was a powerful land-owner while his mother was a distant cousin of the Empress, affording him a comfortable upbringing. Despite this, he wished, from a young age, to follow in his father's footsteps and serve their daimyo - and dedicated himself heart and soul to the training necessary to not simply be accepted as a samurai, which he would have by birth, but to meet the lofty goals the Emperor set for the ideal samurai.
He proved especially capable in early swordsmanship training, focusing on both iaijutsu and the school of bushido swordsmanship created by his great-great grandfather, passed down through generations as the family school.
When he was thirteen, he went one step further, and took the kensai's vow, using his family's money to begin traveling and learning all he could, vowing to become one of the "sword saints" by the time he reached adulthood. He spent two years at this before a messenger found him, insisting he needed to come home at once. When he did so, he discovered that his father had been killed, supposedly by bandits, but there was unexplainable destruction around the scene.
Fifteen year old Hajime swore he would find his father's killer, and followed the clues and tracks he could. Eventually he managed to find the bandits - and his father's sword - but swore that they were not the killers, even knowing they would be killed either way. They claimed that an oddly dressed Chinaman with strange weapons which made loud noises and fired bolts of light and lightning had appeared and hired them to help him take an item belonging to the daimyo the Kazuhiro clan served. Once he had it, he simply disappeared.
Taking his father's sword, he swore he would not rest until he found his father's killer, or he'd die trying. A voice from someone he could not see then spoke up, aking if he meant it. He repeated the vow, looking around, still seeing no one. After asking the question once more, receiving the same response, a three foot tall, cloaked figure appeared, and told him that he would help the kensai then - but expected total obedience in return.
It took some sorting, but the small being eventually revealed himself as a kenku - they had been watching the young swordmaster for years, and saw in him the potential to learn to become one of the true masters, worthy of their training. Hajime followed the kenku to a remote village high in the mountains. They began his training with little further explanation - he carried water up and down the mountains, he ordered all the rocks in the rock garden, then re-ordered them, he fixed the roof, and did countless exhausting, menial chores. When they trusted his obedience, endurance and discipline, sword training began - and turned out to be just as exacting and exhausting - day and night, awoken at any time to draw his sword 1000 times - each having to be just right, or he started over, before being allowed to sleep again. He learned ancient techniques and new innovations from the masters, losing track of the time very quickly.
At long last, they told him that the person who had killed his father was a time traveler, who had come to take a very powerful artifact from the daimyo - and now he was ready to return to the world of men and find him - and in the meanwhile, he would be one of the heroes Japan needed.

Shortly thereafter, he learned that he had been studying under the masters, aging only very slowly in their magical valley, for over 700 years to master every technique the kenku could pass on - to be released into modern day Tokyo.
It was not long before he was arrested. Thankfully, one of the policemen recognized the style of the sword - one of the "lost" blades of Japan's greatest swordsmen. This drew enough attention that he was finally questioned by someone who seemed to believe him - and after a demonstration of skill, and several retellings of his story, Hajime was freed from custody, and taken instead, though very confused, to help re-found Big Hero 6!
