Ren

Ren (蓮, Ren) is a character from Yu-Gi-Oh! ARC-V manga series. He is a mysterious young man working for a woman named EVE and knows a lot regarding Yūya and his personalities.

Appearance
Ren has the same hairstyle as Reiji but longer that he tied two sides. He wears a mask with a V-like alphabet symbol that has two different colours on each side that fully hides his face. His attire consists of a Riding Duel suit with a belt around his waist, two white capes, white trousers, white boots, and a pair of driving gloves that hides a burnt scar on his right hand.

Yūya vs. Sora
Ren first appeared along side EVE, watching the Duel between Yūya Sakaki and Sora Shiun'in from an unknown place. When Sora was defeated by Yūya, Ren rescued Sora under EVE's order. Riding his D-Wheel, he instantly appeared from a dimensional portal, taking Sora with him and disappeared. After he retrieved Sora, he continued following EVE's second order to search through Yūya's memories. Taking opportunity while Yūya was still unconscious from the previous Duel, he found his way into Yūya's mind through hacking his Duel Disk.

Duel Against Yūgo
While looking for Yūya's memories, he was chased by Yūgo who came to stop him. Ren introduced himself and revealed that he knew everything about him, and also about Yūya and Reiji's father, Yūshō Sakaki and Reo Akaba respectively, were the ones responsible for causing a phenomenon called "World Illusion", shocking Yūgo who questioned his identity and motive. Ren couldn't reveal anything further, and instead challenge Yūgo to a Riding Duel, promising that he will leave if Yūgo beat him. When the Duel started, Ren let Yūgo took that first turn and stayed on his spot, commenting in his mind while looking at his burnt scar that Yūgo's D-Wheel, as far as performance of the acceleration, able to deduced that it was tuned perfectly, and that's why he decided to use a type of D-Wheel that was in par with Yūgo's despite the fact he has other better D-Wheels. Ren started his turn by summoning three "White Morays" and then performing Synchro Summon, summoning "White Aura Dolphin" and reduced Yūgo's LP to 2700 and then ended his turn by setting one card. Knowing that Yūgo would be able to prevent his monster's destruction, Ren purposely distracted Yūgo's concentration from him by using his prior tuner monsters. Just as Ren has deduced, Yūgo started to become panicked, which consequently allowed Ren to took the opportunity to pass through Yūgo with his skill and got the next Action Card, commenting his mind that even though their D-Wheels are in par with each other, his experience overpowered Yūgo. In respond, Yūgo Synchro summoned "Clear Wing Fast Dragon" that Ren recognized as Yūgo's ace monster. Already knowing its effect, Ren used his Action Card, "Against Wind" to decrease "Clear Wing's" ATK, but Yūgo then countered it by using his own Action Card "Follow Wing", to increase back its ATK. As he did this, Yūgo recklessly sped up his D-Wheel just when they reached the corner, shocking Ren who was aware it was impossible to keep the balance at the corner and could only watch as Yūgo slipped and fell from the road. To his shock, another road suddenly appeared that saved Yūgo from the fall, and Ren wondered that the road was created because Yūya's consciousness sensed that Yūgo was in danger. Yūgo started to attack back by destroying "Aura Dolphin", but Ren used its effect to revive it back as a tuner monster. The moment he revived it, Yūgo activated "Clear Wing's" effect to change "Aura Dolphin's" ATK to 0. Ren has been waiting for this and activated a continuous magic card "White Salvage" to Synchro Summon "White Aura Whale", and then used the combination of his Action Card and its monster effect to destroy "Clear Wing" and direct attack Yūgo. While Ren succeeded ind destroying "Clear Wing", Yūgo used his trap card to negate the direct attack. Ren reminded Yūgo that his trap card also applied to Yūgo himself, which means he couldn't Synchro Summon for the next three turns. Ren activated his continuous magic card "Synchro Zone" that negate any attack from any monsters except Synchro monsters, completely closing any way for Yūgo to attack since he can't perform Synchro Summon until the next three turns ended. Yūgo then tried to pass through Ren from the right side, noticing that Ren has difficulty in taking the right corner due to his right hand. Already anticipating this move, Ren blocked Yūgo's way. However, his field of vision was suddenly blocked by a mist came from the course ahead of them that was the depth of Yūya's heart, allowing Yūgo, who remembers the course without even looking since he had spent many times riding there, to pass through Ren.

Abilities
As a Riding Duelist like Yūgo, he is very skilled in Riding Duel, able to catch up and even passed Yūgo quickly even though he started late and easily able to ride at 300 km/h in a complex course while Dueling. He is also knowledgeable in D-Wheel mechanism and its various types, having more than one D-Wheels himself. However, due to the burnt injuries he suffers on his right hand, he has difficulty maneuvering to the right side.

Deck
Ren uses "White" Deck, focused on Synchro Summoning tactics. Believing that using complex tactics is a basic Riding Duel strategy, Ren uses complex tactics, which is called "Synchro Samsara" to gather Synchro Materials to Synchro Summon while distracting and provoking his opponent to make them worked up and commit mistakes. To support these tactics, Ren's monsters consists of monsters with effects that enables them to become tuner monsters when it's revived from Graveyard, allowing Ren to continuously performing Synchro Summon.
