Kazuo Tachibana forms one half of the Tachibana twins alongside his brother Masao. Specializing in acrobatic football, they coordinate perfectly as a duo. Initially forwards for Hanawa Elementary School in Akita Prefecture during national qualifiers, their aerial combinations proved a significant threat to opponents like Nankatsu SC. This synchronized playstyle stems from their twin connection, enabling intricate coordination without words. At Hanawa Middle School, the twins developed the Skylab Hurricane technique to overcome Nankatsu Middle School in the national quarter-finals. This acrobatic move involved one twin launching the other for high-altitude shots or passes. While effective, the technique carried high injury risk due to landing strain and collisions. Kazuo served as team captain during this period. For the Japan Junior Youth team, the twins transitioned to midfield. They refined their Skylab techniques under Jito's guidance, creating the Skylab Twin Shot—a collaborative aerial shot with Masao. This technique scored a critical goal against Argentina but injured both twins. Attempting it again against France worsened their injuries, forcing them to play hurt due to substitution limits and jeopardizing Japan's position. After Junior Youth, Kazuo and Masao focused on strengthening their legs and core to reduce injury risks. During the World Youth arc, they were initially excluded from the national team for perceived overreliance on each other. Training independently, they returned with enhanced individual skills. They adapted their aerial techniques for defense, effectively countering high-altitude attacks from opponents like China's Fei Xiang. Against Mexico, their aerial prowess neutralized the "Five Aztec Warriors" until a deliberate foul by García injured them, ending their tournament. Professionally, Kazuo joined JEF United Ichihara with Masao. As adults, acknowledging their matured bodies could no longer withstand the Skylab Hurricane's physical toll, they formally sealed the technique. However, during a critical Olympic qualifier against Australia U-22, they temporarily revived it as center forwards. Successfully executing the move to score Japan's opening goal incapacitated them afterward, but secured the necessary advantage for qualification. Physically, Kazuo shares a resemblance with Masao, characterized by features often likened to a monkey. Their synergy remains foundational, evolving from elementary school acrobatics to professional adaptability while maintaining their identity as a duo.
