Mr. Gongenzaka

Mr. Gongenzaka is a character in the Yu-Gi-Oh! ARC-V anime. He is Noboru Gongenzaka's father, and owns Gongenzaka Dojo.

Personality
Mr. Gongenzaka is a firm believer of the "Steadfast Duel" style, as such he is shown to have be rather narrow-minded and dislikes changes. He assumed that Gongenzaka had stolen techniques from another school when he Synchro Summoned and considered it a disgrace big enough to want to disqualify Gongenzaka from the duel. Despite that, he can be convinced to change his mind if he's impressed, as he accepted Gongenzaka's use of Synchro while staying loyal to the "Steadfast" style.

He's shown to be proud of Gongenzaka and considers him a worthy inheritor of the Dojo. As as teacher, he appears to be rather strict and tough, as shown when Gongenzaka was challenged by him to a "serious match" and the next day had his face covered with band aids.

Pre-Maiami Championship
Nico Smiley arranged with Mr. Gongenzaka a duel between Yūya and Gongenzaka. He was shocked when Gongenzaka Synchro Summoned "Superheavy Koujin Susano-O". He disapproved Gongenzaka's use of Synchro Summon and tried to declare the duel as a loss for him. Gongenzaka defended himself by stating that even the "Steadfast Duel" must evolve otherwise it would be forgotten like an era. Mr. Gongenzaka was still reluctant, but allowed the duel to continue. After watching Gongenzaka use Synchro while still keep his Steadfast style, he accepted Gongenzaka's decision and congratulated both him and Yūya after the duel ended.

Maiami Championship
Before Gongenzaka's duel against Gen Ankokuji, Mr. Gongenzaka approved Gongenzaka's vow to take down Ankokuji and gave him a new sash, which was a tradition of the dojo. After Gongenzaka was selected as one of the Lancers, Mr. Gongenzaka challenged him to a "serious match" to test his resolve, which presumably left Gongenzaka with several injuries.

Yūya vs. Jack
After Zarc's defeat and the Standard Dimension being reborn into the "Pendulum Dimension", Mr. Gongenzaka is seen watching Yūya's Duel against Jack Atlas with You Show Duel School and was happy when Yūya won. He then watched Yūya and Reiji's Action Duel. He was happy when Yūya won the Duel and witnessed Yuzu's revival.
