His name Kiyoshi means " holy or saint " while his surname Kogami can be translated as the " wild goose above " . Biography . History . Dr . Kogami , as a researcher at SOL Technologies , ten years ago , gave free will to A . I . programs , named Ignis , through the Hanoi Project . With his assistants - Azo , Kyoko Taki and Dr . Genome , Kiyoshi created Ignis , for he feared that humanity would be extinct . The AI would evolve , as Kiyoshi wanted a successor for humanity without limitations . Thus , six children were chosen to participate in the project and were forced to Duel , as Kiyoshi believed AI would learn much about humans through Dueling . His son , Ryoken , watched this , and feeling remorse of the children , reported the project to the authorities . However , this caused Dr . Kogami to be imprisoned ; Kiyoshi was infected with a virus and fell into a coma . Kiyoshi finished his project , after which he was declared dead , while SOL Technologies attempted to monopolize Ignis . After three years , Kogami was declared dead . Kiyoshi ' s son , Ryoken , was waiting his arrival . With the help of his subordinates , Ryoken managed to contact his father , who noted Ignis ' progress of creating the Data Material and creation of Cyberse World . Unfortunately , Kiyoshi told Ryoken that Ignis , who would progress , would eventually destroy the world . He believed Ignis would improve humanity ' s lives , and instead , he saw the AI would eventually supervise humanity . He feared the humanity would see AI as an enemy , a life - form they would want to conquer , and this would also make the humanity as Ignis ' enemy . Kiyoshi told Ryoken SOL Technologies knew of this threat , but they only infected him with a virus . With that in mind , Kiyoshi set his mission to stop Ignis , and formed the Knights of Hanoi , believing that they were savage creatures with the intent of destroying the world , rather than saving it . Hanoi . Dr . Kogami approached Varis in LINK VRAINS , who was unable to find Ignis . Kogami promised to make a new program , and suggested they could draw Playmaker out and defeat him , then obtain Ignis back . After their attempt to use Blue Angel to defeat Playmaker had failed , Varis wondered how would Dr . Kogami cope with Ignis ' destruction . Dr . Kogami explained it was a painful decision , but Varis reminded the importance of destroying Ignis and Cyberse . During Varis ' Speed Duel against Playmaker , the latter had Ai conjure a Data Storm . Varis was glad , as this allowed Dr . Kogami to send a card to Varis . Dr . Kogami watched the Duel between Playmaker and Varis , and wished of the latter to take Ignis back . Much to his surprise , Playmaker summoned the " Firewall Dragon " and destroyed the " Fire Prison " . Dr . Kogami was still pleased , as Playmaker had 600 LP left , and expected of Varis to take him down . Dr . Kogami was surprised how Playmaker wanted revenge for what had happened 10 years ago . Specter arrived , noting how scary the fate can be . As Varis returned , Dr . Kogami was surprised how he let his guard down , seeing it was about that incident Playmaker spoke . Varis apologized to him as his father , and as his hand recovered , claimed next time would be different . His father stated that Varis didn ' t need to think of that , and seeing how they could not retrieve Ai , he went to execute the other plan , and needed time to make preparations for that . Kogami and Varis went to a deep pit where he showed Varis a seed shaped like a data cube , which would grow into a " fruit " that would destroy the whole network , including LINK VRAINS . Kogami then released the seed , which fell into the pit . Another . Dr . Kogami contacted Varis , informing his son his program would soon be finished . Varis was depressed , and told his father he wanted to confront someone . Kogami sensed Varis wished to face Playmaker and permitted this as long as it did not take too much time . Akira ran towards Blue Angel , but was trapped in a cage made of vines . Dr . Kogami appeared , explaining Akira would be infected by the virus that would make one lose consciousness . Akira recognized Dr . Kogami as a former employee of SOL Technologies , who died because of SOL Technologies , but was revived . Akira listened to Dr . Kogami ' s personal story , and their mission to destroy Ignis . Dr . Kogami explained anyone that is trapped inside the Tower of Hanoi cannot leave , and once the tower was completed , data worldwide would be erased . Akira was overwhelmed by the fact Dr . Kogami would erase even himself to get rid of Ignis . Dr . Kogami deemed it was the only way they had left , and warped away . Just as the tower was nearly completed , Dr . Kogami approached Varis , asking if he uncovered Playmaker ' s identity . Varis denied , even though he did saw Yusaku ' s face in a footage . Kogami noted ever since the tower was in place , Varis ' interest in Playmaker ' s identity vanished . Regardless , he reminded Varis that even if the world would see them as criminals that took revenge against SOL Technologies , even with all the victims that would soon be erased , he thought one day they would learn the truth of the danger an AI with free will imposed . Varis noted that they were prisoners of destiny , and the fated , final Duel against Playmaker would commence soon , one he intended to win . When Varis failed to execute Storm Access Skill , the Data Storm stopped . Dr . Kogami appeared to his son , Varis . Dr . Kogami admitted he was not a good father to let his son suffer , referring to him as Ryoken , who never complained . He explained he didn ' t want Varis involved in any of this , but reminded without him , the world would be in chaos . While Playmaker and Ai were wondering about Dr . Kogami ' s words , the latter decided to lend his strength in helping Varis to win , all to protect the humanity . Dr . Kogami ' s essence passed onto Varis , who noticed a glitter in the Data Storm , much like the light of the Stardust Road . Varis went through the Data Storm and obtained a new Cyberse monster , but noticed Dr . Kogami ' s heart was damaged and eventually stopped beating . Ryoken , in the real world , mourned his father until Yusaku and Koulter arrived .
