Yūzō Morisaki serves as a goalkeeper, primarily the substitute for Genzō Wakabayashi and Ken Wakashimazu on Japanese national teams, wearing jersey #21. His journey unfolds across the series' arcs. In elementary school, Morisaki replaced Wakabayashi at Shutetsu and later for the Nankatsu selection team. He stepped in during the Shizuoka prefecture preliminaries when Wakabayashi was injured. Initial performances showed inconsistency, marked by poor positioning and a failure to command the defense against Shimada. After being struck in the face by Kojirō Hyūga's powerful shot, he developed a fear of stopping even easy balls. Tsubasa Ōzora helped him regain confidence by teaching the "ball is my friend" philosophy, demonstrated through a defensive Face Block. This stabilized his performances until Wakabayashi returned for the finals. Following Wakabayashi's move to Germany during middle school, Morisaki became Nankatsu's regular goalkeeper. He excelled in the tournament, earning a spot on the All Japan Jr. Youth team. However, with Wakabayashi and Wakashimazu also on the roster, his playing time was limited to brief appearances in two early matches. For the World Youth arc, Morisaki postponed studies to join Japan's U-20 training camp. Wakashimazu's departure and Wakabayashi's injuries saw him start the Asian preliminaries' first round. Against Thailand, he conceded four goals but made a critical save, deflecting a potential fifth goal onto the post, later stating, "for a goalkeeper, the goal posts are friends too." Wakabayashi praised his determination, dubbing him Japan's "Super Ganbari Goal Keeper" (SGGK), emphasizing relentless effort. As a professional, Morisaki joined Shimizu S-Pulse in the Road to 2002 arc. In the Golden-23 arc, he was selected as Japan's Olympic third goalkeeper over players like Nakanishi and Yamada. When Wakabayashi suffered an eye injury and Wakashimazu was registered as a forward, Morisaki became the starter during the Olympic Asian preliminaries' third round. He kept clean sheets against Vietnam and Saudi Arabia—the latter featuring skilled scorers Owairan and Vulcan—and delivered a spirited performance against Australia. During the Rising Sun arc Olympic quarter-finals against Germany, Morisaki replaced the injured Wakabayashi after Wakashimazu was benched. He soon conceded a goal from Karl-Heinz Schneider's Jumping Fire Volley. Later, he prevented a German lob and initiated a counterattack with a long pass to the "Golden Duo," though their shot was blocked. In extra time, he showed solid reflexes but was overpowered by Schneider's Compact Fire assisted by Kaltz. He then suffered an injury from Schneider's Reactive Fast Kick Quick Fire. Morisaki's goalkeeping relies on courage and intuition over advanced techniques. His known moves include the "Parada aguerrida" (Tenacious Save), a full-stretch one-handed save, and "¡Que me dé en algún sitio!" ("Hit Me Anywhere!"), a last-resort technique spreading limbs to block shots with his body. Trivia notes his first unnamed appearance in chapter 3, name revealed in chapter 12. Latin American dubs named him Al Jones/Crocket; some European translations used Alan Crocker/Parker. "Ganbari" translates to "hard-working," contrasting him with Wakabayashi's natural genius.
