Datastormshipping

Datastormshipping is the slash ship between Ryoken Kogami and Yusaku Fujiki from the Yu-Gi-Oh! fandom.

Canon
Ryoken and Yusaku have known eachother since they have been 6 and 8 years respectively. They met when Ryoken ran into Yusaku, which made him drop his deck and together they picked up the cards. Ryoken invited Yusaku to play with him. During the season we learn that Ryoken's father, Dr. Kogami, conducted an experiment with a company called SOL tech, on AI programs. He wanted to create an AI that learned duelling from humans so he kidnapped young children and forced them to duel for survival. One of the kids was Yusaku, who nearly died during the experiment due to malnourishment. Only because of Ryoken's voice and him stating 3 reasons for Yusaku to think about to keep on living, Yusaku survived. He never learned that it was Ryoken who saved him. After 6 months the children were rescued, but they never knew how or who called the police. They all went back to society, but had to undergo severe psychological treatment, because of their kidnapping.

Season 1
During season 1 we learn from Yusaku, who is now 16, that he plans to take down an organisation called Hanoi, which is connected to Dr. Kogami. He got himself an alias Playmaker to go into the Vrains, a computer program, and defeat them. Yusaku states that he never forgot what happened to him and that even the treatment couldn't fix all the damage his brain had to endure, while being captured. He also believes that the kid, whos voice he heard is still captured somewhere and he tries everything to save the child.

When he encounters the leader of the Hanoi, a guy named Revolver, and they duel. During that he states 3 reasons why he will take down Hanoi, while the leader gasps in clear recognision. Yusaku wins the duel and gets a part of Revolver's data to analyse. When Revolver returns to Hanoi's hideout, it is clear that he is Ryoken, because he speaks with his father Dr. Kogami.

At the climax of season 1 Yusaku and Ryoken duel again. Yusaku speaks of Ryoken as his first friend and the person he wanted to save, while Ryoken remembers Yusaku, but doesn't want to be his friend, because he is after Yusaku's AI.
