Sumaki Aikawa was the third born child to Haikaido Aikawa, an infamous retired Yakuza cleaner. Her older brothers, Sai and Nobushiro, were born of a different mother than Sumaki and 14 years prior to her,respectively. Even though there was a large age gap between them, Sumaki and her brothers shared a deep sibling bond. Haikaido had lost Keiko Musada ( Sai and Noushiro's mother ) to his chosen profession. She could not take the stress of living under the yolk of the Yakuza, so in exchange for leaving her sons with him, Keiko was allowed to go, without fear of assassination, as long as she did not divulge any information about what she had seen while living with Haikaido.She has not been heard from since. It was then, some time later, that Haikaido met Tamako Honda ( Sumaki's mother ). Tamako was a mid level consultant for one of the fronts of Haikaido's Yakuza lord, Fumito Watanabe. She was being robbed when Haikaido had happened to chance by and saved her. After this point, the two started to see more of each other. Eventually, the two fell in love and Tamako was soon heavy with child.What was to be a joyous event was soon met with tragic complications. On the night before Sumaki's birth, Tamamko was poisoned with a variant of blowfish toxin that had been intended for Haikaido. It was, also, on the this night that a rival Yakuza lord, Shotobu Naga, staged the first of two attacks on the Watanabe compound. Naga had counted on the fact that Haikaido would not be part of the battle, having been poisoned, and thus, would have an easier hostile takeover. This, sadly to Naga's plans, was not the case. Fueled by the rage that his love had been poisoned, later too find it was by one of Naga's spies, Haikaido cut a path of death through the invading party. While Haikaido and his men repelled the attackers, the compound dotor attended to Tamako. ( She ) begged the doctor to save her child, as it was a symbol of her and Haikaido's love for each other. The doctor performed an emergency Cesarean section and Sumaki was brought into the world, health and strong. This happiness was short- lived, however. Soon after giving birth, Tamako began to succumb to the effects of the toxin. Tamako died holding her baby in her arms, with no fear in her teary eyes, stating to her newborn that she did not regret her life with Haikaido and that ( Sumaki ) would grow to be a strong woman. With her last breath, Tamako named her child Sumaki Aikawa ( giving Sumaki her father's last name as a final gift to Haikaido,as they were never married ). Haikaido arrived some twenty minutes later to find his new daughter crying in the arms of the nurse and the sheet pulled over Tamako's body.
Sumaki grew up happy under the watchful eye of her father and brothers. When she was not studying, she would be often found in the company of either Sai or Nobushiro. Even though Sumaki was born into the criminal element, her father taught her to respect to the letter of the law, both traditional and modern. While not a genius, Sumaki was exceptionally intelligent for a child her age and easily picked up on different concepts and mannerisms early. It was because of this learning development that Haikaido soon began teaching her the martial arts. Much to his joy, she was an avid student and a quick learner. To make sure that Sumaki would grow up valuing life, Haikaido emphasized non-lethal techniques in her teachings ( i.e., many joint locks, pressure point strikes, quick take downs, and a variety of knockout blows ) This way of education would continue , not only in her tutelage of her father's " Iron Wolf " Kenpo but ,also, in her instruction of the internal martial arts from China. It would not be many years later until she could begin to utilize the abilities both forms of martial arts would allow her to use.
While growing up, Haikaido had a small house built on the compound to raise Sumaki away from the day to day business of the Japanese mafia. When neither her father nor her brothers ( who had joined the ranks of the Yakuza, under their father ) could be present, attendants saw to Sumaki's educational and personal needs. ( She ) was free to roam around the compound , as long she avoided certain forbidden areas. A good deal of the habitants of the compound came to love Sumaki, as she would try to assist where ever she could when she had free time to herself. Even the Yakuza lord, Watanabe, came to regard the child in a positive light. However, these happy times were soon to end. It was on the year of Sumaki's seventh birthday that there was a major betrayal within the Watanabe compound. One of Watanabe's other hit men, Toshi " Killswitch " Mako, had grown envious and resentful of the favoritism shown to Haikaido by Watanabe and lusted for more power and acclaim.
Secretly, he met with the vessels of the rival Yakuza lords, Shotobu Naga and Hiro Takanawa, and planed a staged attack on the compound. A deal was struck, in return for helping them take down Watanabe, he , himself , would be made into a Yakuza commander, under the two opposing Yakuza lords, and have precedence over the compound as his base of operations. On the night the raid was to take place, Mako had drugged the guards and unlocked the main gates. All he had to do now was right for the moment to strike from behind while everyone would be concentrating on the invading forces. All would have gone to plan,if not for the unexpected arrival of Sumaki to the front gates. She had decided to bring the guards a cake she had made, in thanks to them for showing her how to juggle earlier. She came upon the drugged guards and began running back to her father , shouting at the top of her lungs. Hearing this, Mako rushed to the child first to ask what had happened. As Sumaki began explaining what she had found , Mako had taken out a knife, intent on killing the child, lest his plans be ruined. Sumaki had turned back toward Mako just in time to see him trying to deliver the killing strike. It was only because of her quick reflexes that she was able to fall backwards, avoiding the complete attack, receiving instead a deep cut across her chest, a scar that remains with her to this day. Scared and bleeding, Sumaki ran as fast as her legs would carry her to find help but Mako had caught up with her. As he reached for her, Sumaki turned around suddenly and lunged directly for his face, stabbing him in the left eye. Screaming in both pain and surprise, Mako retaliated by kicking the child in the mid section, sending her bouncing across the courtyard . By the time that she came to a stop to catch her breath,Mako was ,again, right on her ready to finish what he had started. This time, an intervention came in the form of a rather quick kick to the side of ( his ) head, sending him sliding across the courtyard. Sumaki's timely savior was none other than her father, Haikaido, coming to see where the screaming was coming from. Seeing her father holding her brought Sumaki the comfort of protection she needed and fainted. Haikaido was furious to see that his daughter was the subject of , not only, a cowardly attack but a betrayal of one thought to be a friend. Haikaido ,so enraged, beat Mako to death with his bare fists, ultimately leaving his face unrecognizable.
Haikaido now had a difficult decision to make as he ran ,with Maki tightly pressed against his chest: Try to fight back the overwhelmingly large growing force now administering destruction and ruin to the compound or get his injured daughter to safety, thereby, abandoning his honor and loyalty to his lord. This issue plagued his mind as he fought through the invaders to reach the inner garden, the one place he knew that would be fortified enough for a regrouping.The inner garden had an old stone half house in middle surrounded by clay brick wall. it had only three windows, one on each side and one to the rear, and also had a solid oak door. Inside, there was an old fountain where water was still running. There were two channels leading from the base of the fountain, each from either side,heading toward and out of the walls of the old house. These channels were used to carry fresh water to the whole garden,via the channel that ran through each of the planting plots. It was here that he found a group of ten men lead by his sons, Sai and Nobushiro,trying to gather others in an attempt to gain back some ground. Haikaido told them who was responsible for their current situation and how this betrayal would now be the downfall of this house. Setting Maki down on a bench by the fountain, Haikaido ripped off sections of his shirt to both clean Maki's wound and make improvised bandages to cover it. It was soon that word reached reached the party, by way of an injured comrade, that Lord Watanabe had been captured. The compound had now been officially lost and the rest of it's inhabitants were either being captured or killed. Haikaido knew that if he or any of his family were caught, they would be killed immediately as a matter of precaution, due to his skill and reputation. Looking down at his unconscious daughter, Haikaido shed a tear, because he knew in his heart that he had failed to protect that which was most precious to him, his family. Standing up, he commanded the men inside to hand over most of their weapons, keeping with them only what they needed to escape. Haikaido had resolved to be a distraction while the others fled with Maki. It was about this time that the invading forces of Naga and Takanawa could be heard outside, readying a final assault.
The voice belonged to none other than Mako, who was now quite certain of his victory. Mako's words made Haikaido's blood boil over with rage and was ready to head out the door,guns blazing, letting no force on earth stop him until he had brutally killed his traitorous former friend.However, both Sai and Nobushiro stopped this from happening. They explained to their father that there was another way out the compound right where they were. The whole of the compound was once a feudal lord's summer home, and as such, contained many hidden routes of egress. Having, like Maki, grown up on this land, both sons had found many hidden passages,some not known even to Watanabe himself. One such exit was a pull away door under the cobble stone floor behind the fountain. They explained that this passage connected to an old waterway that would lead them a small wooded park area some two miles away where an escape could be made. This information brought hope back to Haikaido's eyes, as now his children had a means of surviving the ongoing slaughter outside the walls of the garden house. As Haikaido began to tell his sons to flee with their sister, Sai abruptly stopped him. Sai began taking the majority of Hakaido's weapons away from him, while at the same time, Nobushiro had picked up Maki and placed her in their father's arms. Sai explained to his father that it was HIS duty to safe guard the well-being of their sister, stating that she would need a father more than she would brothers. Nobushiro likewise added that that ,as Yakuza retainers themselves, they were honored bound to stay and fight. This ,however was not the reason why they were going to stay behind. Haikaido was going to need time to reach to the end of the waterway,meaning all but three would have to stay behind and hold off the attackers from following anyone escaping. Haikaido would need someone to watch his back as he escaped with Maki so one of the men there was ordered to protect Haikaido and Maki at all cost. Haikaido, of course, protested this plan but realized, in his heart, the sacrifice his sons were willing to take to ensure their sister's safety. As they talked , the hidden door was uncovered and made ready. Both Sai and Nobushiro gave Maki a kiss on the forehead as their final goodbye. Nobushiro gave the order to attack and the fire fight began. Awakened slightly by the awful den of gunfire, Maki just barely caught a glimpse of her brothers before Haikaido entered the passage with her in his arms. Her last memory of her brothers before falling unconscious again was that of both Sai and Nobushiro giving her their reassuring smiles, the ones they had always given her to ease her when she felt troubled.
This would be the last time Maki saw her brothers alive.
