Genzo Wakabayashi, known internationally as Benji Price in some adaptations, comes from a wealthy family in Japan's Shizuoka Prefecture. From elementary school, he showcased exceptional goalkeeping talent under coach Tatsuo Mikami, who envisioned him becoming the world's best. This early era earned him the nickname "SGGK" (Super Great Goal Keeper) and forged his belief that football transcends wealth or status. At Shutetsu Elementary, Wakabayashi displayed initial arrogance, demanding honorifics from teammates to motivate them. He provided access to his private training facility, aiding peers like Mamoru Izawa and Hajime Taki to improve. His leadership propelled Shutetsu to a national championship. A pivotal street match rivalry ignited with Tsubasa Ozora when Tsubasa scored against him, fueling Wakabayashi's competitive drive. Aged 12, Wakabayashi moved to Germany, joining Hamburger SV's youth academy. He endured initial bullying due to his foreign status but persevered, forming a significant bond and rivalry with Karl-Heinz Schneider after Schneider scored against him in training. This period sharpened his resilience, linguistic skills—achieving fluency in German—and tactical understanding. He ultimately became Hamburg's starting goalkeeper and Germany's top youth keeper. Wakabayashi's integration with Japan's national teams proved complex. Playing for Hamburg in a friendly against Japan, he adopted a villainous role to motivate them, criticizing Kojiro Hyuga's leadership after a 5-1 win—an act orchestrated with Mikami to strengthen Japan's resolve. He later joined Japan's U-19 squad as backup goalkeeper, supporting Ken Wakashimazu until Wakashimazu's injury forced his substitution in the World Youth Championship final against Germany, which Japan won 3-2. His professional career at Hamburg featured intense Bundesliga matches, including a notable 2-1 loss to Bayern Munich where a risky offensive play drew criticism. Reduced playing time followed, prompting his focus on Japan's Olympic team during the "Golden-23" arc. Wakabayashi anchored Japan's defense in Asian Olympic qualifiers but sustained a severe eye injury against Australia, sidelining him for the remaining qualifiers. Physically, Wakabayashi grew from 161 cm and 55 kg in elementary school to 183 cm and 77 kg professionally. His goalkeeping style emphasized fundamentals over acrobatics, relying on precise positioning and reflexes. He famously claimed no one could score against him from outside the penalty area, a boast broken only by elite strikers like Schneider, Sho Shunko, and later Natureza. Recurring injuries—particularly to his arms during the World Youth Championship and his eye against Australia—underscored his willingness for physical sacrifice. Key relationships encompass his enduring rivalry-turned-friendship with Schneider, his mentorship of Yuzo Morisaki, and his respectful yet competitive dynamic with Tsubasa and Hyuga. His development across all official media arcs traces a journey from privileged prodigy to selfless team pillar, consistently striving to elevate Japan's global football standing.
