Yūgo/Relationship

Yūto
Yūgo seems to know Yūto and said that he wanted to pay him back in the duel. Yūgo also gets angry at Yūto when he calls him "the pawn of fusion" thus prompting Yūgo to angrily tell Yūto that he had the nerve to get his name wrong and take "what's important" to him, but Yūto argued back saying that Yūgo took something important to him.
