Sam

Sam' (サム Samu) is a character in the Yu-Gi-Oh! ARC-V'' anime. He is a Commons who works for the Tops at events.

Personality
He is very reluctant to look others in the eye or give his own opinion. Sam previously admired Jack Atlas, but after he misinterpreted Jack's gift of the "Tuning Magician" card he developed a fierce hatred for him and the Tops.

Past
Sam was employed by the Security and Executive Council of the Synchro Dimension. However, he refused to make eye contact with his peers or give his opinion. On one occasion, he met Jack Atlas at an event and he explained that he was a fan of his. Jack gave him a card, "Tuning Magician", which he explained suited Sam. Sam interpreted this as an insult, given the card's low Level, 0 ATK, and its effect.

Friendship Cup
When Yūya tried to talk to Sam about Jack Atlas before the exhibition match of the Friendship Cup, he was nervous and didn't realize Yūya was talking to him despite being the only other one in the room. After Yūya's defeat, he gave Yūya "Tuning Magician", believing the latter could defeat Jack. Sam was later present during Yūya's discussion with Reiji regarding Reira

Round 2, First Day Match
Sam watched the Duel between Yūya and Shinji. He was surprised to see Yūya use the card he gave him, "Tuning Magician", to Synchro Summon "Enlightenment Paladin" and win the Duel with it. Although he was overjoyed when Yūya won, he was shocked when Shinji and the Commons painted Yūya as an ally of the Tops and he started to distrust Yūya, especially due to the untimely arrival of Jean-Michel Roger.

Sergey Volkov vs. Jack Atlas
Before the semifinals match, Sam talked to Jack about how he finally understood why Jack gave him "Tuning Magician". He also learned from Jack that all cards and people had a purpose and was given the task of delivering this message to Yūya.

Commons Rebellion
Sam went to look for Yūya to tell him that Jack was not impressed with his Duel with Crow. Jack also instructed Sam to tell Yūya, if that wasn't the Duel he truly believed in, to come to the Duel Palace and challenge him to a Duel. He then returned to the Duel Palace with Yūya, Gongenzaka, Frank, Amanda, and Tanner, but they couldn't get in due to the Commons blocking the entrance during their riot. Just then Shun, Chojiro, Shingo, Reiji, and Reira appeared while riding Shun's "Raid raptors". They rode on with them to the Duel Palace, where Yūya challenged Jack Atlas to a Duel.
