Kanoho was born during the year 2056 in a rural part of Japan, bordering the city of Yamagata, as the younger of two brothers. Both of his parents worked at the Yamagata Police Agency, leaving him and his brother mostly in the care of a local youth center. Like every other child that did not grow up with the luxury of gaming centers or manga cafes in their neighborhood they spend most of their time studying. Math, History, Chemistry, Languages all were a daily part of Kanohos childhood, leaving only the bare minimum to cause mischief with his brother. The remainder of their time was spent under the tutelage of their father, a strict but generally kind man.
His lessons mostly concerned themselves with the basics of self defense, public laws and how to be a "good man"; namely by following the rules, standing up for oneself and others and not be afraid to find your own path in life.

When meta abilities first started gaining attention amongst the general population, Kanohos initially quiet and calm childhood was rapidly thrown off track, as he developed his own quirk around his eight birthday. His father, for fear of him "infecting" his brother soon began isolating Kanoho. When even the local hospital, in whose care Kanoho had been given
at the beginning, saw now way of reverting his condition, and more and more younger children started showing signs of similar changes, the fear in his father turned a darker shade.
Soon he began imposing more and more limitations on his son. He was not allowed to linger at school after classes, not allowed to invite or visit friends, not allowed to go outside unaccompanied.

Time passed and his fathers leash tightened like a noose around Kanohos neck. Long gone where the days where he would enjoy his studies and spend quality time with his brother. Despite not having developed a quirk of his own, their fathers strictness had by now too reached Kanohos brother. Not permitted to partake in the usual time of leisure as other teens, he spent almost his entire time in his room, studying for upcoming exams and being educated by his parental captor.
It was by sheer coincidence that Kanohos life changed, when he witnessed a group of youngsters race past their house on the way into nature. The teenager were blasting loud music and seemed to be enjoying their life loudly, a fact that would have surely angered Kanohos father, had he been awake to see the spectacle.
Kanoho however, merely realizing the obvious, found a glimmer of hope in the sight.
It didnt take long for him to take up his courage and sneak out of the house at night for the first, but not last, time.

This first night he didnt dare go out more than a few blocks; mostly to see if he could, but with every passing month he became braver. Soon he found himself leaving his home regularly during quiet nights and began skipping school too in an attempt to regain some of his former freedom.
What began as a simple way of escaping his fathers ire, over time turned into a means to vent. As he met more and more "delinquents", as his father would have called them, he came to understand that most of them had not been treated this harshly by their family. They broke the rules not because they had to, but because they could, their rebellion a mere act of chance and opportunity and not necessity.
And as with many others before him, Kanoho felt the spirit of his paternal upbringing reaching out for him.
Them breaking the rules for fun seemed too much like an inexcusable offense to him.
The first time he assaulted another teenager was when he spotted a group of young boys, trying to break into one of the few local supermarkets to get snacks and cheap booze. When a fight arose it became clear that none of them had a chance against the quirked up youth.
With this Kanoho finally felt free again. Of course it didnt take long for his father to put one and one together and realize that his own son was the mysterious assailant that kept beating up the other village boys. For the first time outside of traditional training, Kanoho found himself on the receiving end as his father tried to beat some sense into him.
From there on things escalated as both tried to enforce their respective rules; Kanohos father on him and Kanoho on anyone else he met.
His teachers had long learned to stay away from him as he was continuously growing bigger and broader and more aggressive. Having established himself as the defacto leader of the local thugs ment he was free to operate however he saw fit and Kanoho made full use of this, passing on the bullying he had to endure at home to any one within reach.
For a whole year things got tenser and tenser every day, until the metaphorical string of fate finally grew taut and snapped, and with it the patience of Kanohos father. He confronted his youngest and a heated conversation turned soon into a full argument, which then turned into a one-sided brawl.
Finally, Kanoho stopped holding back and with a strong enhanced strike he threw his father backwards, straight into the door that led into his brothers room. The frame cracked, sending his father tumbling backwards through the door and into the darkness behind.

The next day, things had changed. His father didnt impose any rules on him, didnt even bother to look his way, which suited Kanoho just fine. He let off steam in town, breathing both in anticipation as well as relief.
Time passed, and after a few weeks Kanoho had already forgotten their little altercation.
This saw a sudden end, when one day a group of big and brawny men in army colored suits appeared before the families house.
Kanoho, who had just come back from a drinking binge with some of his friends, barely bothered to register their presence, as they approached his father in the living room.
They quickly got his attention when two of them barged into his room, each holding a mancatcher and a menacing grimace.
Despite his best attempts Kanoho found himself pinned two the floor in moments. Under his parents determined and teary eyes the men dressed him in a black gown that allowed for limited movement and led him into a large truck outside.
It was only later that Kanoho found out about his fathers final solution.

Leaving his brother and his friends behind, Kanoho was introduced into a regional military boarding school that promised worried parents to take great care in handling their differently-abled offspring and return them as disciplined and mature individuals, ready to fit back into society.
What they didnt tell parents was the exactly process through which this was to be accomplished. A prison like system of rules and regulations greeted the young Kanoho when he arrived at the schools gates, still bound. His hair was shaved, his clothing confiscated and exchanged for a durable and simple uniform and his every movement watched by armed guards.
By day he was expected to perform in school, minus all the niceties. The same material as before but packed into information-dense tabs of one hour each, ment to be taken dry and uninspiring, with teachers that might as well be straight from the frontlines.
During off times a strict schedule of physical exercise and weapons training awaited him, ment to exhaust him to the point of inability to use his quirk. Breaking of the rules resulted in corporeal punishment and prolonged physical exercise.
The first weeks were hell, as Kanoho tried to escape or otherwise revolt against the controlling environment almost daily, but a quick reminder of the difference in strength between an soldier and a young adult dulled his rebellious spirit soon. Bruised and battered he had no other choice than to accept his fate and roll with the punches. His will was finally broken when his parents came to visit him some time after, a bleak affair, mostly for appearances and ended with Kanoho wailing and screaming at his parents to let him out.
Unbeknownst to them, this day, more than any other, left a mark on Kanoho when his father told him, that it was his own fault that he had to be kept in the boarding school. After all, HE was the one, that had broken the rules, whereas the school staff was free to act how they saw fit, as they were the ones enforcing the rules.
Feeling abandoned by his parents Kanoho sank back into social isolation after this, keeping away from the other students for several weeks before his spirits slowly returned.

Teenager are adaptable if nothing else, and so he soon learned to draw whatever entertainment he could from his new world.
Using his quirk to overcome the harsh physicality of the boarding school, he threw himself fully into the system. To any outside spectator it mustve seemed like the system was working as Kanoho became more controlled and even channeled his past misbehaviour into reprimanding younger children during class for overstepping boundaries. After a while it seemed like nothing had changed compared to how he had been before attending the military school. Goons and thugs swarmed to him, only to be whipped into a shape that mirrored the vision of the school council, and where Kanoho had been met with violence and punishment before he was now praised as one of the most successful residents of the school.
Six years he stayed at the establishment, slowly working his way up amonst its involuntary recruits. Initially his family kept visiting him every now and then, but after the second year even this brief contact stopped.
Kanoho didnt mind.
His opinion changed when he was released from his school and sent back home, where broken walls and a lonely door, barely hanging in its frame was all that was left.
It turned out that roughly two years after his admittance a fight between a major criminal group and the local police force had escalated when the gang began employing quirked youths as enforcer. During that conflict his father had tried to reason with some of the teenagers, even going so far as to offer shelter and support from their overseers, but instead of resolving the situation he had merely managed to paint himself as the prime target.
Overnight the gang struck, ambushing him at his own home, and leaving nothing but ruins.
When Kanoho was informed of this he didnt know how to react. He had been given a simple one bedroom apartment, financed by his fathers colleagues, where he stayed by himself for a week.
When he finally emerged he had made up his mind. His application to join the police was a first step to rectify the flaws he saw in society. Before long he had made a name for himself, a competent young officer stepping into the footprints of his deceased father.

At a time when more and more criminals employed their powers to their own benefit, every quirk empowered member of the police was considered of great merit. Kanoho was quickly placed into a special troop with other officers with meta abilities; however they quickly realized that with the current rules in place they were little more than meat shields for the unpowered officers and many rulings that would be used to incarcerate criminals were just as easily abused to stifle their own progression.
And yet Kanoho persisted for several years. His strict military background, direct personality and adherence to the rules, made it hard for any superior to actively act against him.
Only when he saw an opportunity to gain a form of independence did the troubled young man, that he had become, leave active duty. Traveling to Tokyo in 2075 he partook in one of the earliest classes of professional heroism at the U.A. University. Older and more experienced than many others in his class he found it easy to keep up with the curriculum, but hard to adapt to the fluid lessons and individualistic rules. Ultimately he left the university during his third year and returned back to Yamagata, where he finished his education at a government-funded Hero course. At this point Kanoho began operating under the Heroname "Courtroom Cannon", a moniker that originated from the two different ways that his name could be written as.
Known for his violent treatment of villains and very direct approach to "diplomacy" has given him a sort of infamy amongst the rural population; with older citizens often supporting his no-nonsense type of law enforcement.

Would it not have been for a coincidental news story that caught his eye a few months back, he would have most likely stayed in Yamagata for all his life.
Fate however had other plans. As it was, he happened to pass by a small store after a mission and found his eyes roaming the newspaper articles where he noticed a familiar looking face.
The story mentioned a rise in villains throughout Japan, originating from Tokyo, and used a big attention catching image on its front page. A photograph of a group of heroes battling some villains, and in the background a face that looked an awful lot like his brother.
Now the Courtroom Cannon has transferred to Tokyo, to make sure that this story ends right before it can begin.
