Chojiro Tokumatsu

Chojiro Tokumatsu' ( Tokumatsu Chōjirō) is a character in the Yu-Gi-Oh! ARC-V'' anime. He is the "boss" of the Facility, even higher in authority than the local guards.

Past
Chojiro used to be a Duelist from the Commons who was admired by children there, including Crow and Shinji. This earned him the nickname "Enjoy Chojiro" from his fans. One day, he gained opportunity to Duel duelists from Tops to prove his skill, but the Tops Duelists used their money to gain rare cards and defeated Chojiro. The resulting loss caused Chojiro to cheat in professional duels in order to defeat his Tops opponents and regain the love and admiration of his children fans. However, he was imprisoned for his action, leading Chojiro to lose his faith in the purpose of Dueling for fun.

For the past ten years in the Facility, Chojiro defeated many Duelists with his combo and gained many rare cards that allowed him to have a luxury life in the Facility and eventually made him the boss of the Facility itself.

Chojiro vs. Yūya
While eating an exquisite dinner one morning, Chojiro took notice of Yūya Sakaki, Shingo, Crow, Shinji, Gongenzaka and Dennis Macfield. Later, he had the Security guard bring them to him, and Chojiro's lackeys demanded that Yūya and his friends hand over their cards to him in exchange for good treatment. They refused, and Chojiro showed them the bed-sized stack of cards that he'd claimed over ten years in undefeated Dueling. Disappointed that Yūya wasn't listening to reason, he had the guard bring them Duel Disks and challenged Yūya to a Duel. Performing a long combo, Chojiro brought out "Cardian - Ameshikou" on his first turn. He was surprised when Yūya performed a Pendulum Summon, wondering if Dueling had advanced to this point in the ten years that he'd been imprisoned, and used "No Cheaters Allowed" to return the Summoned monsters back to Yūya's hand.

However, Yūya continued to stall the duel with set monsters and 'Entermate Raingoat'. As Yūya turned the duel around with Pendulum Summoning, he began to bring happiness back to Chojiro and the inmates watching before winning the duel.

Prison Break
Since his loss, Chojiro treated Yūya and his friends nicely, even giving them some of his breakfast to eat. He then decided to hold an Entertainment Duel Tournament to cheer the inmates, inviting Yūya and Shingo to participate, which they agreed to. To make it more exciting, Shingo proposed for them to do Action Duel, which allowed them to activate Action Field and use Action Cards. The Duel initially went well until the guards caught Crow, Shinji, and Damon's attempt to escape, abruptly stopping the Duel. Chojiro angrily confronted Yūya about this, the latter apologised for lying to him but he couldn't stay because he needs to save his friend. Indebted to Yūya, Chojiro decided to help and escape together with him and his friends. With the help of the other inmates, they successfully escaped through the air ventilation and made it outside at the rooftop where they were confronted by the Arrest Corps. Shingo tried to defeat them, but was quickly overpowered, prompting them to escape by jumping from the rooftop and safely landed on Yūya's "Entermate Trampolynx". Unfortunately, they reached a dead end and cornered until Gongenzaka and Shun saved them.

Entry to Friendship Cup
They reunited with Crow's group and proceeded to make their escape, but the Security trapped and recaptured them. Before they could be taken back to the Facility, the Council ordered for them to be taken to their place for questioning. There, Chojiro and the others were shocked to find out about the interdimensional war and that Lancers were from different Dimensions. To prove their alliance, the Council ordered them to enter the Friendship Cup, including Chojiro and the others despite them being the residence of Synchro Dimension. Chojiro pointed out that he has been imprisoned for ten years in the Facility, but the Council emphasised that there's no exception, much to Chojiro's delight who always wished to enter the Friendship Cup. He was then taken to the room for Friendship Cup participants along with the others except Yūya who was chosen to Duel Jack in the exhibition match.
