Yūto

Yūto (ユート), is a character of Yu-Gi-Oh! ARC-V anime. He is also known as known as The Dark Duelist although it wasn't until Episode 21 that his name was revealed on-screen. He has a strong resemblance Yūya Sakaki and is on the search for a dear friend that has been kidnapped.

Appearance
Yūto's strong resemblance to Yūya Sakaki reached to the extent where, both, Shingo Sawatari and Yuzu Hiragi mistook him for Yūya. Yūto has black hair and purple bangs at the front where he sweeps them both up to the side. His skin is slightly olive with grey, dull eyes that were covered with goggles - he eventually abandoned them after they were destroyed in his duel with Shingo - as well as wearing an army mask to cover the lower section of his face. Yūto's punkish, gothic clothes consist of a greyish-green shirt with a dark blue tie and are accompanied with a black coat with ripped edges from the sleeves and bottom. He wears black pants that are held up with a brown card belt and shoes. Notably, he wears a red scarf tied on his right arm. Accessories include a black, spiked choker and matching wristbands.

Abilities
Yūto has the ability to inflict real damage and injury to a duelist and surrounding in a duel, and cause a fire, etc. He is also good physically, like jumping around and fighting using his Duel Disk, which he was first seen doing it when he encountered by Sora Shiun'in.

Entomology
Yūto has many definitions depending on the kanji used. For example: 優 (Yū) means "Gentleness" and "Superiority", 悠 (Yū) means "Distant" and "Leisurely". The last syllable 人 (To)  means person, 翔 (To) means to "Soar" or "Fly".

Past
Yūto lived in a ruined world which could be in fact destroyed Heartland City from ''Yu-Gi-Oh! ZEXAL''. One day, he encountered a D-Wheeler Duelist, "Yūgo". He dueled him with his ace, "Dark Rebellion Xyz Dragon" to defeat the Synchro Monster. The White Duelist was cornered, so he ran off. Then, Shun Kurosaki came, asking what happened and about Ruri Kurosaki.

Pre-Miami Championships
The Black Duelist is a mysterious duelist who is targeting the Leo Duel School. He first appeared to take the place of Yuzu Hīragi's duel against Shingo Sawatari. Before taking the duel on, he said to Yuzu he doesn't want to see her getting hurt anymore. In the first turn, all he did was set Spell Cards. Later in the duel, he Xyz Summons his ace, "Dark Rebellion Xyz Dragon". He was inflicting real damage in the duel. After defeating Sawatari, he took off his mask, where Yuzu and Sawatari became confused and thought he was Yūya Sakaki. When Yuzu's bracelet shines, he disappeared without a trace. The confusion makes Sawatari to complain Yūya was the culprit. A Xyz Duelist attacked Marco, who was Leo Duel School. This could be suspected to be The Black Duelist's attack. Because of this, Reiji Akaba forfeits his duel with Yūya and leaves to research on the case. When Yuzu goes back to the place The Black Duelist was last seen by her and Sawatari, and brought along Sora Shiun'in to learn Fusion Summon, The Black Duelist came back. This time, he was noticed by Sora who suddenly starts jumping and going around to catch him. Then, both Sora and The Black Duelist fought using their Duel Disk. Sora Shiun'in said to him, "You're not from here, are you?" and then The Black Duelist replied "Neither are you". He disappears again because of Yuzu's bracelet. At the time, Masumi Kōtsu also thinks Yūya was the culprit. He has been staring at Yuzu since they first met. When Yuzu's bracelet shines for the third time, he is teleported to the place where Shun Kurosaki was.
