Yūgo Sakaki/Relationship

Yūya Sakaki
Yūya is Yūgo's younger brother. Both are very close with each other since their childhood. Yūya was always cheering for Yūgo whenever he was Riding Dueling, and this becomes Yūgo's main encouragement whenever he is starting to lose his confidence. Like Yūto and Yūri, Yūgo is protective of Yūya, having swore to himself that he will always protect Yūya at all cost, which becomes his main motivation to keep on fighting. Together with Yūri and Yūto, Yūgo will do anything to avoid making Yūya sad, even if it means erasing the past memories they have shared together. He even cried for Yūya when he saw a fragment of Yūya's painful memory, immediately destroying the memory so Yūya doesn't need to go through with the pain again and stated that he will never forgive the one who made Yūya suffer. Yūya's concern for Yūgo is shown during his Duel against Ren, in which Yūya sensed Yūgo is in danger and subconsciously saved him by creating a road within his mind when he fell from the road. He also followed Yūgo's instruction in riding D-Wheel without complaining and continue to train hard, fully believing his older brother who has more skill and experience in Riding Dueling.

Yūto and Yūri
Yūto and Yūri are Yūgo's brothers. They get along well, though there are lot of times they prone to argue over little things. Yūgo was easy to be offended by Yūri's remark despite his attempt to cheer him up, and he found Yūto annoying whenever he thinks the latter being bossy and doesn't quite like riding D-Wheel with Yūto sitting behind him because he is loud. Regardless of their rather clashing personalities, they nevertheless are close with one another, showing concern for each other's well-being and would lend a hand for the other. The three of them also shared the same need and determination to always protect Yūya, which brings them even closer. Although, at the same time, their love for their younger brother also formed a rivalry between them for Yūya's affection.
