Yusaku Fujiki's History
When he was a child, Yusaku ran on the streets when he accidentally bumped into a fellow boy, whose name was Ryoken. They accidentally dropped their cards, and quickly collected them. Seeing Yusaku was a Duel Monsters fan, Ryoken invited him to his house to show his Deck.[3]

Young Yusaku rescued from the Hanoi Project.
Yusaku was one of the six kidnapped children, who were used for the Hanoi Project. He woke up in a white, empty room, with VR goggles. He placed them on, and was forced to Duel, with the penalties of being both electrocuted[4] and having nothing to eat if he lost. This repeated on for months, as he tried to Duel on. After six months passed Yusaku collapsed,[5] a voice told him he should not give up, and advised him to think of three reasons why to continue fighting,[6] who turned out to be Varis.[7]
Yusaku receives counseling for his trauma.
Yusaku asked who the voice was, but the voice told him he'd soon go home. The system was disbanded, and while Yusaku was rescued, the incident was covered up and not mentioned in the media. Regardless, Yusaku refused to believe he was rescued from the incident, as he developed PTSD afterwards. Over the following years, he underwent therapy to heal his trauma and tried to live a normal life, but the torture he experienced was too painful for him to forget. Eventually, Yusaku took his Deck and resolved to "face his destiny" by getting revenge against the Knights of Hanoi, whom he believed to be responsible for the "Hanoi Project".[5] He had the robot, Roboppi, to clean his house. He was pleased whenever he saw the robot, who enjoyed doing the chores to please his "master".[8]
Yusaku went to LINK VRAINS under the name "Unknown" to hunt Knights of Hanoi grunts and interrogate them over the Lost Incident. One day he helped Kolter, named Unnamed, hide from the Knights of Hanoi. The Knights of Hanoi could not find Kolter, who climbed across a wall. Unnamed thanked Unknown, and stated they were alike, but Unknown reprimanded him for now knowing anything about the Knights of Hanoi. Unnamed explained he was trying to uncover information involving his brother with an incident that demolished his life. Unknown, who was asked about the Lost Incident, still stated that Unnamed had to get out to value his life, as Unknown logged out. Kolter, as Unnamed, continued to investigate the incident in LINK VRAINS. One day, however, the Knights of Hanoi cornered him, and just as Unnamed believed he could not get out of this, Unknown appeared.[9]
Unknown rushed to his aid, stating Unnamed should still watch over his brother, and the incident was not his fault, either. Unknown decided to fight the knights, and pointed a path where Unnamed could log out. Unnamed did so, leaving Unknown to fight one of the knights. Kolter rushed to the computer, where he watched Unknown Duel the knight, who belittled Unknown for daring to face the Knights of Hanoi. Unknown, who swore to take his revenge, summoned "Photon Thrasher", "Marauding Captain" and "Exarion Universe" to set up a Link Summon of "Gaia Saber, the Lightning Shadow". The knight played "Limiter Removal" to double the ATK of his "Jack Wyvern". Not only did Unknown counter that effect with "Forbidden Lance", but he played his own "Limiter Removal", and defeated the knight in a FTK. The knights were held aback by Unknown, who asked them about the Lost Incident.[9]
The knights did not know about that, since they were simply hunters after Cyberse cards. Unknown saw it was a waste of time to confront them, and jumped away. Since the knights cornered him, Unknown jumped through a portal, created by Kolter. As Unknown had escaped, he was told to visit Café Nom in Den City. Unknown did so, and bought a hot dog from Kolter. He thanked Kolter for saving him, referring to him as Unnamed. Kolter was shocked that Unknown was so young, and explained he was investigating the Lost Incident, for his brother had been a victim of that project. He asked for Unknown's help, for they could save his brother from the suffering. Kolter introduced himself, offering his skills to Unknown to protect him in LINK VRAINS. Unknown acknowledged his call and confirmed he'd help Kolter, and introduced himself as Yusaku Fujiki.[9]
Unknown saves Unnamed before the latter fell into the trap.
For a while Unknown continued to fight Knights of Hanoi minions, but none of them had the info they needed. Kolter doubted they needed to speak with them, reminding they were in LINK VRAINS to hunt after Cyberse cards. Yusaku noticed Kolter was investigating something: the latter explained there was a legend of a dungeon inside LINK VRAINS. Its creator was being hunted by the Knights of Hanoi, and set up the dungeon to protect themselves and the Cyberse deck. Kolter laughed the legend off, but Yusaku pondered the thought, since the knights were hunting Cyberse cards. Believing the knights were afraid of Cyberse cards, Yusaku concluded that could be the weapon against their enemies.[10]
Thus, Unnamed and Unknown went into a dungeon inside LINK VRAINS. Just as Unknown went to alert Unnamed, the latter stepped on a trigger plate and nearly fell in a chasm of spikes, containing Duel Disks. Unknown caught Unnamed, who thanked him, noting the creator of the dungeon watched too many movies. He believed he'd take a lot of damage, but Unknown stated that without his Duel Disk, he wouldn't be able to log out. Unnamed still believed the dungeon to be a trap by the Knights of Hanoi. Unknown didn't mind that, for they were still searching for information about the Lost Incident. However, since the Deck was being hunted by the Knights of Hanoi, Unknown believed that would give them the attention needed so the knights would come after them. Unnamed noted how far Unknown has planned, who pressed a plate and revealed a secret passage, containing a sarcophagus and some plates. Unnamed and Unknown knelt, as a Knight of Hanoi entered the area, pleased that he finally found the place.[10]
However, the knight's Duel Disk was hit by a light from the sarcophagus, as a preset Duel was initiated: the goal was to beat this Duel Quiz. Unnamed was angry that the knight got before them, but Unknown stated this was a tough quiz to solve. The two noted the goal was to defeat the enemy, a data ghost, who had 4000 LP, five Extra Linked monsters and a set card, while the knight had two monsters and two set cards. The knight attempted to win by equipping "Megamorph" to "Update Jammer", and had it attack the enemy's "Link Spider". The data ghost played "Chaos Burst", negating the attack, destroying "Update Jammer" and defeating the knight. For losing the Duel, the knight was devoured by a data monster, and his Duel Disk was impaled. Unnamed commented this was no ordinary game, for the knight was strangely logged out. Unknown jumped down, for he came to acquire the Cyberse deck. Having his Duel Disk get hit by the light, Playmaker initiated the Duel Quiz.[10]
He revised the situation as the same as the knight's, but noted "Dotscaper" in his GY, and three Link Monsters in his Extra Deck: "Proxy Dragon", "Secure Gardna" and "Binary Sorceress". Unnamed recalled that "Update Jammer" negated card effects, but Unknown stated "Chaos Burst" was played before the attack, and why the knight's strategy had failed, considering it would've negated "Megamorph", too. Unknown revised that "Tremendous Fire", "Torrential Reborn" and "Thunder Crash" dealt effect damage. Revising these cards, Unknown thought of the strategy to defeat the data ghost. He summoned "Cyberse Gadget" to revive "Dotscaper", and used the two monsters to Link Summon "Binary Sorceress". Just as Playmaker proceeded at his next action, a Knight of Hanoi appeared, laughing at Unknown, since he could not win. The knight proclaimed he'd have the deck, but Unnamed bumped into him and used a handcuff to bind him.[10]
Unknown, however, used "Dotscaper" and "Gadget Token" to Link Summon "Proxy Dragon", them used "Binary Sorceress" to Link Summon "Secure Gardna". The knight and Unnamed saw it is over, since Unknown used all of his monsters to Link Summon. Unknown replied he'd never give up, else they'd never take revenge on those that made them suffer. Unnamed agreed, for they'd never learn the truth behind the Lost Incident if they gave up. Unknwon used "Tremendous Fire", but since that would inflict damage on him, he used "Link Restart" to negate that damage and revive "Binary Sorceress". Using "Thunder Crash", Unknown destroyed all of his monsters and inflicted 1500 LP damage to the data ghost. Combined with "Torrential Reborn", Unknown revived his monsters and inflicted 2500 LP damage to the data ghost, thus winning the Duel. Unknown and Unnamed ran towards the sarcophagus, but it turned out to be just an illusion, and the Deck was not present. The knight laughed that was a prank, and logged out. Unnamed was frustrated that there was nothing, and the dungeon started collapsing, and two logged out.[10]
Kolter and Yusaku celebrate upon finding the Cyberse deck.
Instead, Kolter and Yusaku went to the warehouse district, for the Duel Quiz was actually a map that showed Den City. Kolter claimed Yusaku could've summoned Link Monsters in different positions, and the map would've looked different. Yusaku confirmed this, but the connections between the Link Monsters still symbolized bridges, and they found the door where a card of "Secure Gardna" was placed, at the same spot Yusaku summoned that monster in his Duel. Opening the door, the two found the actual sarcophagus. Touching it, Yusaku unlocked the sarcophagus containing Cyberse cards. This cheered Kolter up, who stated that deck symbolized his bond with Yusaku, and the two crossed hands with each other.[10] This was all arranged by Ai, who wanted Yusaku and Kolter to work together, and acquire the Cyberse Deck to fight against the Knights of Hanoi.[11]
Assisted by Kolter, Yusaku hunted the Knights of Hanoi with the Cyberse deck. He changed his avatar name to Playmaker,[10] and over time, Playmaker became a famous duelist known for being able to stand up against Hanoi, with no one knowing his real identity because he always deleted his activity logs.[12]
