Lin began his training hidden away from any contact with modern society, and ever since he can remember, he only lived to obey orders, and to eliminate all those who represented a threat to his clan. Grown bitter and cold, Lin gathers enough features to be a ruthless ninja: along with his antisocial behavior, Lin's abilities exceed those of any other Hizoku ninja. His incredibly quick speed allows him to move in a blur, his hands as sharp as any sword, and a hidden presence, which not even the wind could find. Lin had became a true Hizoku ninja, except for the fact that he couldn't turn his blood into poison....

Throughout the years, as time flew by, Lin was assigned the task of eliminating all those who would betray the Hizoku. And while several students of the Hizoku style tried to escape the harsh training periods, or attempted to reveal its' secrets, would quickly end up being swiftly dispatched with excess of violence by Lin himself, who would eliminate them with his killing techniques, making his victims suffer and finally die from utter pain by consuming the poisonous blood of Lin.

Years later, Lin discovers that several villagers have disappeared the last few months. The number grew considerably, so Lin was sent to investigate. Using his supreme stealth tactics, Lin manages to track down a suspicious kidnapper. When he finally follows him to his hideout, Lin ambushes the criminal, and obligates him to cough up the truth. The name "NESTS" sprouted for the first time in Lin's mind. After informing this to his superiors (and eliminating the spy), Lin is assigned his most important task yet: to infiltrate the next King of Fighters tournament, and eliminate any NESTS agent in his way.

To enter the tournament, however, Lin needed a team. By then, Lin had finally managed to gain the ability to turn his blood into poison, but regretfully finds the risk of it: doing the process wrongfully would quickly lead the user to a swift death. Lin needed full concentration in order to survive, not just from NESTS but from himself as well.

In a nice day of training up in the mountain range of China, Lin could feel the presence of an incoming man, who was brave enough to show his foolish carcass near Lin's whereabouts. Lin devised the man as a rather tall, bulky, black man, wearing a fancy suit. No doubt, some fancy agent trying to follow the track of his murders. Lin said nothing to the man, despite his constant questions about his skills. He should die. There was no other way. Lin attempts to stab the large man in the chest for a quick kill, and resume his training, but surprisingly, the huge oaf pushes Lin aside. Lin is surprised at the man's speed and skill to avoid such a lethal blow. Before Lin could strike again, the man introduces himself as Seth, a man who knew the whereabouts of the NESTS organization. Lin was interested in what Seth had to say, and although quite reluctant to form a team (being the sociopath he is), Lin accepts Seth's offer to enter the KOF tournament.

When Seth and Lin travel to Japan to meet up with their new teammates, Lin gets to meet Seth's old friend, Benimaru Nikaido, and Benimaru's close companion, Shingo Yabuki. Lin tags them as worthless fighters. When the ever- friendly Shingo tries to strike a conversation with the ominous ninja, Lin's short temper runs dry, and in a swift rage attack, attempts to do away with Shingo. Having seen Lin's obscure intentions, Benimaru anticipates the attack, and strikes Lin away. This was the first time Lin was ever repelled like that. Lin now vows that he won't let Benimaru get away with his audacity....

During the tournament battles, Lin constantly gets into fights with Benimaru, due to contrasting personalities (sounds a lot like a formal relationship, eh?). The sheer rudeness and violence of Lin clashes with the beautiful, self-centered attitude of Benimaru. The problems, however, don't seem to affect the team's performance at all, as the team reaches the finals. There next battle will take place in Southtown, in the factory zone. Lin boils in anticipation of a final battle with NESTS.

When Lin and the others arrive at the designated point, they find it odd to be an abandoned factory. Lin feels a strange presence among them, but suddenly, Benimaru rejoins with Maxima, former partner of Benimaru and Shingo, as well as a former NESTS agent. Lin, ignorant of this fact, asks who they are, but the question is cut short when suddenly, the whole factory is surrounded by NESTS soldiers! Lin confirms his suspicions, and escapes along with the other fighters, to a dark room.

In the room, Lin is shocked by the fact that it was a set-up by one of the main NESTS followers, Zero. He plans to use everybody's fighting energy in order to activate the Zero Cannon and destroy everything from outer space...even NESTS! Lin vows vengeance, as he discovers that several Hizoku ninjas have been eliminated for snooping around NESTS' business. Lin takes action when the situation is most desperate, and when Benimaru and the others are near defeat. He manages to concentrate all his strength and poison blood in one stab in Zero's back. Zero beats Lin around afterwards, but the damage had already been done: Lin's deteriorating blow weakens Zero enough for K' to deliver the final blow.

After Zero is defeated and the Zero Cannon fired, Lin barely manages to survive. However, he is met with one final challenge: Ron, his old rival, has shown up to kill him! Lin senses something odd about Ron: not just his disfigured appearance, but also his incredibly evil aura. As Ron reveals later, he has offered to be a NESTS' guinea pig, and now he has sold his soul in favor of eternal power. Lin condemns him as a traitor to the Hizoku cause, but Ron is ready to eliminate him anyway. Benimaru manages to save Lin at the nick of time, though, as he appiles an Elec-Trigger against Ron, who manages to break free from Benimaru's grasp. Lin recriminates Benimaru's action, but inside him, he is grateful that someone would do something for him. Perhaps friendship might have a meaning after all....

Ever since, Lin has been conducting an investigation of his own. Lin has scouted several NESTS locations, according to his sources and using his ninja stealth to infiltrate these places. Lin was seeking out the traitor Ron throughout the world, but could not yet find him. Every place was just abandoned, leaving Lin to find out from scratch again. During another raid on yet another abandoned NESTS base, Lin casually stumbles upon K', Maxima, and Whip, who also happen to be renegade NESTS agents. Lin was tied up by the trio and talked into confessing his plans. Despite refusing to talk at first, Whip knew he was after Ron, considering his objective in the last tournament, and offers Lin to join them in the next King of Fighters tournament to find out where Ron is. Lin will not bother with the three of them, but accepts to help only out of personal desire. Having said so, Lin escapes, but promising to come back to the tournament....

In fact, Lin did arrive to help K' and the others out in order to exact revenge on NESTS for ruining their lives. Lin would not comunicate too much with the other team members, but he did his job done: he would inject his lethal poison into the blood of his opponents to wither them down to nothing. Lin was precise and deadly. It seemed like he couldn't be stopped. Lin felt an ominous presence creep in his heart as he entered the blimp that would take him and his team to the final battle. Fully aware that it would be nothing more than a trap, Lin follows. It is, in fact, a plot held by the original Zero to eliminate them. After having his clone stage the last King of Fighters tournament, Zero would now do the job personally. But Lin is not interested in Zero. Lin spears the floor with his hand, and almost in an instant, Ron materializes from beneath. Lin knew Ron was in hiding all this time, but now that the games are over, he should eliminate Ron for the lost honor of the Hizoku clan. As K' and the others deal with Zero and his other teammates, Lin stands ready to finally fight Ron.

The power of the two Hizoku ninjas clashed over and over again. Their blinding speed cruised the whole chamber, slashing and hacking at each other. It seemed like no one could gain the upper hand. But after K' defeats Zero, the ship in which they were travelling finally docks in some dark place. Ron takes advantage of the confusion to escape, leaving Lin a bit disappointed. But Lin has to force himself into escaping from the ship as it begins to self-destruct. With a bitter feeling, Lin now has to stand against Igniz and his ambition to become a human god, betraying his own cartel to fulfill his purposes. But it seems like Lin's purpose is gone: he no longer bothers with the tournament, even after Igniz is defeated by K', and sets the whole space station where the ship docked into a crash course straight towards the planet. Lin has no trouble in escaping among the whole chaos, but he wonders how much time it will take, and how much will he resist hunting Ron down for so long? His only answer seems to rely in the hope of a better life that everyone seems to express after NESTS has fallen....

Having been trained to be non-sentimental and downright cruel, Lin is not the one to lend others a helping hand. He only thinks about what's good for him or his clan. Never having learned the true meaning of love or friendship, Lin is a bitter man with little to say but a lot to kill. His poison blood is risky for his health, but he considers it a risk that he must take in order to become stronger. Lin admires Benimaru's courage, and Shingo's tenacity. Perhaps he can learn something from it...?
