Sanzyudai Yuki is a character based on Jaden Yuki (who is known as Judai Yuki in Japan) who appears in the Tag Force series.



The name Sanzyudai appears to be a pun on Judai, which is Jaden Yuki's given name in the Japanese version. The name 十代 (jūdai) literally means "teenage" or "ages 10-19", befitting Jaden Yuki's youth. On the other hand, Sanzyudai appears to be significantly older than Jaden, which is reflected in the name 三十代 (sanjūdai), meaning "the thirties" or "ages 30-39".


Tag Force

In Yu-Gi-Oh! GX Tag Force, Sanzyudai Yuki asks for the player's aide in his, Senjome & Sironos' aide in their feud against Emperor.Umiuma and the rest of UmiumaCorp. He appears in the morning at the cafeteria of the Slifer Red Dorm after the player has completed the game with 3 or more Page 1 characters.

In Yu-Gi-Oh! GX Tag Force 2 , to Sanzyudai's annoyance, he is partnered with Emperor.Umiuma, and in order to be allowed to change partners, he must duel at least once. He challenges the player and his partner to a Duel, and upon victory, he allows the player to partner with him. He appears during a Random Event at the Main Gate after the player has completed the Story Mode with 4 or more Page 1 Characters, and have beaten both Jaden and Yusei Fudo 15 or more times each.


In Yu-Gi-Oh! GX Tag Force, Sanzyudai uses a Stall Deck focused on dealing effect damage while skipping his opponent's Battle Phases with D.D. Borderline.

In Yu-Gi-Oh! GX Tag Force 2 and Yu-Gi-Oh! GX Tag Force 3, Sanzyudai uses Monster Mash Decks to quickly power up "Chaos Necromancer" with "Magical Merchant".
