Appearance
Shūzō has dark blue eyes and brown/orange hair. He often wears a red/orange jumpsuit with a green trim and red fire design. Underneath, Shūzō wears a dark blue shirt with another fire design.

Personality
Shūzō is an enthusiastic and passionate person, often using the catchphrase "hot-blooded" whenever he's excited. He is one of comic relief character in the series due to his goofy and dramatic tendencies, causing Yuzu to hit him with her paper fan, but he can be serious if the situation calls for it. He takes great pride in You Show Duel School and does everything he can make it prosper.

He is very fond of his daughter and likes to dot on her, feeling uneasy to the point of hysterical when Yuzu was not around such as when Yuzu temporarily stopped coming to school to train with Fusion Summon with Sora instead of asking him, and got puzzled when there's a boy too close to her as seen when Yuzu Duelled Dennis.

According to Yōko Sakaki, Shūzō has the skills to become a Pro Duelist, but believes that winning isn't everything in a Duel. In addition, Shūzō acts as mentor and a somewhat father-figure to Yūya Sakaki in the place of his good friend and senior, Yūshō Sakaki.

Etymology
His name "Shūzō" may refer to a former professional Japanese tennis-playerShuzo Matsuoka who is also known as hot-blooded and energetic like Shūzō Hīragi. Shūzō Hīragi also plays a sport-related Deck ("Guts Master"). Shuzo Matsuoka hosts the "Shuzo Challenge", an annual tennis camp for young children, while Shūzō Hīragi owns the You Show Duel School for young Duelists.

Past
Shūzō used to be an Entertainments Duelist who is also Yūshō's junior and close friend. During his times as an Entertainment Duelist, he often bring baby Yuzu along with him to his Duels. A few years afterwards, he retired as an Entertainment Duelist and helped Yūshō to establish You Show Duel School and become the school's headmaster.

Pre-Maiami Championship
Shūzō ran into the Solid Vision machine's room when Yuzu accidentally destroyed it. Afterward, he was in a state of panic, as he bemoaned that his teaching career and the school would be over. He refused to let Yūya Duel against Strong Ishijima, but was excited when Nico offered the school the newest Solid Vision technology for free. However, Yuzu smacked him on the head with a paper fan and criticized him for going against his word. Later, Shūzō, Yuzu, and Gongenzaka went to the Dueling arena to watch Yūya's Duel against Ishijima. After the Duel, Shūzō returned to You Show Duel School, where he saw Yuzu defeat Yūya in a Duel. Tatsuya Yamashiro signed up for the school, which excited Shūzō. Not long after those events, Shūzō hosted a Duel between Yūya and Sora Shiun'in, who claimed that he would soon enter You Show Duel School. Shūzō chose "Wild West Duel Town" as the Action Field, but Sora complained about it because it was boring, so Shūzō changed it to "Sweets Island". Sora lost the Duel to Yūya, and much to Shūzō's joy, enrolled in You Show Duel School.

You Show Duel School vs Leo Duel School
Soon after that, Shūzō was teaching his six students more about Duel Monsters. He was surprised when Yuzu asked him if he could teach You Show Duel School how to Xyz Summon. Shūzō responded that Xyz summoning was too complicated for him to teach. Later on, Himika Akaba arrived at You Show, blaming Yūya for Shingo's injuries. Shūzō said that Yūya wouldn't harm anyone and agreed to Mrs. Akaba's deal: if LDS defeated You Show Duel School, the small school would belong to LDS, and vice versa. Shūzō chose a space action field for Yūya and Hokuto's Duel, resulting in a embarrassment for Shūzō, because Hokuto would thrive in the Duel's action field. Shūzō was near the Solid Vision machine and loudly asked Yūya to pardon his foolish act. Mr. Hīragi was happy that Yūya won the duel, and got disappointed when his daughter lost to Masumi. Sora refused to duel Yaiba, so Gongenzaka was Shūzō's last hope. Gongenzaka tied in his Duel with Yaiba, worrying Shūzō about the small school's future. He witnessed Yūya Duel Reiji Akaba and was surprised to see the LDS president Fusion, Synchro, Xyz, and even Pendulum Summon, stating that none of those summoning types were in Reiji's profile. Shūzō's worry returned when Yūya's duel got paused but was relieved that Himika and the other LDS members left.

Yūya vs. Shūzō
Yūya was shell-shocked that Reiji had been able to Pendulum Summon. Tatsuya encouraged Yūya to teach them about his Pendulum Summoning, but Yūya yelled that Pendulum Summoning wasn't his anymore and he tried to run off, only for Shūzō to stop him. Shūzō told him off for running, pointing out that nothing wouldn't change if Yūya fled from it, despite the fact that other people could Pendulum Summon had shown up. Shūzō pointed out that one day the world could be overflowing with Pendulum Cards, given Reiji's status as the CEO of the Leo Corporation. He ordered Yūya to Duel him, so that he could beat Yūya's pessimistic personality into shape. They Dueled in Yūshō Sakaki's signature field, and Shūzō told him he'd show Yūya what a real Entertainment Duelist was like. Yūya protested at his Duels being called fake, and Shūzō claimed that Yūya's Duels were not comparable to his or Yūshō's. Forcing Yūya to reveal his hand, Shūzō harassed him, and Yūya Dueled for a turn without using his Pendulums, despite having both his Magicians in his hand. When Yūya's attack failed, he claimed that Yūshō's Duels were more entertaining than Shūzō's, a fact that Shūzō agreed with. Shūzō pointed out that Yūshō's Duels weren't always like that and initially attracted criticism, but eventually, the jeers became cheers. He told Yūya that to open a door to a new world, one with courage had to push it, and Yūya had opened a new door called "Pendulum." But they wouldn't be exclusive to him anymore, soon anyone could Pendulum Summon. To prove it, he took control of the Magicians and used them to Pendulum Summon more monsters. Shūzō commented that Yūshō would have been overjoyed and improved his skills, while Yūya was shocked instead, and encouraged Yūya to set and example and hone his skills. but ended his turn without attacking and returned the Magicians to Yūya (due to his card conditions). Regaining his confidence and taking a step forward with courage, Yūya defeated Pendulum Summon three monsters and used them to defeat Shūzō. He was glad that Yūya finally got back to being his normal self.

Yuzu's training
Shūzō later found out that Yuzu was taking Fusion lessons from Sora and got upset, assuming that she thought that her father's Dueling teachings weren't good enough for her. He told her about her bracelet after hearing her get upset about it. Shūzō had no idea why Yuzu got upset when she got home. Later on, he was seen in a room, throwing cards on the ground, one by one. He told Yūya that he had lost his daughter's trust in him.

Yūya vs. Gongenzaka
Some time after that, Shūzō, his You Show students, and Yōko were secretly watching Yūya's Duel against Gongenzaka. Shūzō accidentally spoke loudly at one point during the match, so Sora told him to be more quiet since they did not want Yūya to find out that they were watching the Duel, leaving Shūzō embarrassed. He was later shocked to see Gongenzaka Synchro Summon and was happy when Yūya won.

Maiami Championship Arc
Shūzō told his students that he was very proud of their skills. He told them in which groups they would participate during the championship, but they left after hearing him talk too much, something Shūzō was oblivious to. He and the You Show students traveled to the Maiami stadium to watch the Maiami Championship. During the opening proceedings, Yōko and Shūzō cheered Yūya and the others. After Yūya's brief mess-up and subsequent speech, Shūzō believed that Yūya could catch the famed duelist Yūshō Sakaki but Yōko affirmed that he could surpass Yūshō. He watched Futoshi's Duel with Takeshi Shimizu and congratulated him for winning.
