Street Fighter EX/Kairi

Background
Kairi grew up with his two younger sisters, Hokuto and Nanase. They were all students of the legendary Mizugami style of fighting. Kairi loved his sisters and would do anything to protect them. One night he began having nightmares in which he harmed and even killed them. He began to fear that this would come to pass in real life. With his mind beginning to fray, he left his clan in order to protect his loved ones. He wandered the world, and as he did, his memories became more tattered and broken, slowly replaced by the nightmares he continued to experience.

The First Tournament
He continued to train on his own, and he was told about a Street Fighter tournament by a fellow fighter in a white gi with a similar style of combat. Intrigued, he entered the tournament. Between his fights, he went to watch another match. To his surprise and horror, he witnessed Hokuto fighting, and fled to get away from her in case he might harm her. Hayate noticed his departure and chased after him. Kairi stood helpless as he watch Hayate approach, but before he could reach him, a mysterious fighter knocked Hayate out of the way with a single blow.

The fighter introduced himself as Akuma before he launched into one of the deadliest attacks Kairi had ever faced. Kairi struggled to defend himself, but Akuma's attacks were almost demonic in nature. The first rising dragon punch that Akuma performed grazed Kairi's face and damaged one of his eyes. Kairi was slowly succumbing to Akuma's attacks. Kairi began to lose his mind, and when he opened his eyes, it was not Akuma that he saw attacking him, but Hokuto. Traumatized by the thought that his nightmares were becoming true, he suddenly gathered all of the ki in his body and errupted in a burst of light which knocked Akuma off his feet and stunned him for the first time in a long while. Then Kairi blacked out.

The Second Tournament
When Kairi awoke, he had no memory of who he was, or of the fight that had taken place. He did not know where he was, and when he looked in a puddle at his reflection, he saw a face that he did not recognize with long white hair and a scar over one useless eye. Kairi began to wander the world looking for fighters to combat. Unless he was fighting, his mind was a jumble of confusing images and upsetting emotions. He only found peace in battle, which he sought wherever he roamed.

He heard about a Street Fighter tournament, and he decided to enter. He was surprised when people referred to him as a returning contestant. He proceeded to win battle after battle, ripping into opponents with a cold effectiveness that few had ever seen. He was challenged to a fight by M. Bison, and Kairi accepted. However, before the fight was fully underway, the fight was interrupted by the demon Garuda. Garuda, seeking Kairi since the first tounament, knock Bison out of the way with a single blow. Bison slumped against the wall and Garuda proceeded to attack Kairi with the intent of killing him. Eventually, Bison regained consciousness and, enraged by the interruption, launched at Garuda with a Psycho Crusher attack. A fight between them ensued, and Kairi simply got up and left.

The Awakening
Before his next scheduled fight, there was an argument between the officials and his next opponent. They were trying to convince a little girl to remove herself from the fight even though she bested several opponents. She refused and challenged Kairi to battle, referring to him as big brother. Kairi dismissed her remark as insanity and proceeded to fight her with all of his might.

His opponent, Nanase, was quick and seemed to predict every move that he could throw at her, as if she knew him somehow. The little girl ran tirelessly in circles around him and seemed to be trying to wear him out. But she underestimated how much Kairi would take, and Kairi let a huge burst of energy loose around him, taking Nanase by surprise. Nanase realized that her brother would probably kill her without a second thought and began to cry. Kairi was about to finish Nanase when her tears caused him to hesitate. Seeing Kairi pause, Nanase closed her eyes began yelling all of her cherished memories of Kairi to him.

She continued to yell for minutes at a time, until she felt a gentle hand on her head. She opened her eyes, and it was Kairi, looking down upon her and smiling. Kairi remembered who he was, and the love in his heart for his little sister changed the effect of the power that he was under. No longer interested in combat and death, he realized that he had a purpose in life, to remove tyrants from the world and save those who are helpless against them. And in order to succeed, he needed to find his sister Hokuto.

No longer concerned with the tournament, he asked the officials for the whereabouts of Hokuto, and he and Nanase ran to the location of her last fight. They saw a dead body being taken away. Horrified, they ran to see if it was her. They were more horrified to find out that it was in fact Hayate, Hokuto's lover, and that he died at her hands. They began asking witnesses where she went off to, and slowly tracked her down. When they found her, she was in a complete state of panic over what she had done. Kairi and Nanase wrapped their arms around her and they were surrounded by a warm glow. Hokuto's panic disappeared.

The Third Tournament
Kairi began to train with Hokuto. He knew that he needed her help to defeat the likes of Shadow Geist and M. Bison, and he knew that in order for her to help him, she needed to be able to tap into Chi no Fuuin at will. For months, they prepared and entered the third EX tournament together as partners to put an end to the madmen who hosted the previous tournaments.

To gain access to the two tyrants, Kairi and Hokuto had to successfully beat the other opponent partners. One night between fights, Hokuto bid Kairi good night, and Kairi remained outside to watch the stars. He sensed an ominous but familiar presence behind him, and he turned around to find Garuda ready to strike at him. Kairi blocked the strike and countered. They fought for a long time before Garuda began to gain the upper hand. Slowly, Kairi was losing ground and Garuda nearly succeeded in his mission to destroy Kairi. Thoughts of his sisters flashed in Kairi's mind and once again, he gathered all of his ki, but this time he was able to release it in a focused beam directly on Garuda. The beam caused Garuda to disintegrate, and he was never heard from again.
