Dr. Kiyoshi Kogami (鴻上 聖, Kōgami Kiyoshi) is a character appearing in the Yu-Gi-Oh! VRAINS anime. After being declared dead and his physical body left comatose, he continued to exist as an avatar in the network for seven years, and as a member of the Knights of Hanoi with his son as its leader. When he was alive, he was known as the creator of the Ignis and a researcher at SOL Technologies.



His real body has tan skin and wears a grey outfit.

Inside LINK VRAINS, Dr. Kogami is a tall man, who has fair skin. He has black and grey hair and mustache, and has yellow eyes. He wears a white coat with red outlines, a dark undershirt with red stripe, some black pants and a pair of brown shoes.


Like Varis, Dr. Kogami believes the Ignis to be a threat. However, since he did create the Ignis, he has slight regret about destroying them. Dr. Kogami is both calm and collective, and rarely shows any emotion apart from a brief smug smile when Akira Zaizen got caught in his trap. Similar to Yusaku, he greatly desires revenge on the ones who wronged him i.e SOL Technologies but while Yusaku still cares for others well-being Dr. Kogami is willing to cause the deaths of thousands of people by destroying the network, not even caring that he himself would be erased.


Dr. Kogami can teleport himself inside LINK VRAINS. In addition, he has superior programming and hacking skills, even helping out his son in dire need from a remote distance.


His name Kogami means holy or saint while his surname Kiyoshi can be translated as the wild goose above.

Dr. Kogami's real comatose body.

Dr. Kogami, as a researcher at SOL Technologies, planned and executed the Hanoi Project 10 years prior to the start of the series.[3] He was working with Faust and Baira, who didn't like the project due to its inhumane nature.[4] His work successfully gave free will to A.I. programs and named his creation Ignis.[5]

When the Hanoi Project came to light, SOL Technologies imprisoned Dr. Kogami in order to cover up the incident, as well as attempt to monopolize the Ignis for high profit. SOL Technologies infected Dr. Kogami with a computer virus with an intention of silencing him, putting him into a coma. Three years after the Hanoi Project, he was believed to have died, and was publicly declared dead,[3] but his consciousness continued to exist in the network. His son, Varis, was able to remove the virus, and recreate his mind in the network, but is left taking care of his comatose body.[2]. At some point later on, Dr. Kogami and Varis formed the Knights of Hanoi, with the intent of eradicating all the Ignis within the network, believing that they are savage creatures with the intent of destroying the world, rather than saving it.


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.[2] 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.[6]

During Varis's 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.[7] 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.[5] 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.[1] 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.[3]


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.[8]

Dr. Kogami later appeared in LINK VRAINS and confronted Akira Zaizen, explaining what happened to him, and that the Tower of Hanoi would annihilate all data on a worldwide scale, before vanishing.[9]
