Adam

Adam (アダム Adamu) is a character in Yu-Gi-Oh! ARC-V (manga) series. He was the lover of EVE and presumably the first person to came into contact with G.O.D. He is the reason EVE and her group seeks to awaken G.O.D's true power.

History
Adam came from distant future. He was a scientist who worked together with his lover EVE and their friend Isaac. One day, they found G.O.D and materialized its power into the form of a card. During one of the experiments, Adam saw glimpses of the past, present, and future through G.O.D. Recognizing its power and wished to use it for the benefit of humanity, Adam continued the research on the card despite EVE's objection. As EVE has feared, the experiment gone awry, forcing Adam to sacrifice himself to seal G.O.D's power and stopped its rampage at the cost of his body disappeared and his soul wondering through time and space.

While wandering, Adam saw a man-made gate that led him to see the outcome of G.O.D's rampage: Destruction of various universes. Realizing how dangerous G.O.D is but he is unable to stop it due to lacking Dueling skill, Adam waited and seek strong Duelists to be entrusted with the pieces of G.O.D power that he has stolen, the Adam Factors. After long wait, he finally found two youths he believed would be able to stop G.O.D, Yūya Sakaki and Reiji Akaba. During World Illusion, he gave the Adam Factors to them.

Meeting Reiji
When Yūya and the others infiltrated EVE's hideout and split up, Adam's soul contacted Reiji for the first time. He apologized for involving Reiji and Yūya into conflict against G.O.D, but he has no other choice as his Dueling skill is poor compared to EVE and Isaac. He revealed while he actually could meet his friends, he decided against it since he was still holding a fragment of G.O.D while EVE was holding the G.O.D card itself and feared G.O.D might take back the Adam Factor if he go near it.

He continued to explain what he saw beyond a man-made gate that shows the destruction of various planets as the result of G.O.D's power. Reiji then asked if Adam came to meet him to take back the Adam Factor he had given to Reiji.
