Description
Tatsuya Yuuki, also known as Meijin Kawaguchi III, is a major figure in the Gunpla Battle community. His childhood was shaped by strict family expectations, leaving little room for hobbies until age seven, when a friend named Toru introduced him to Gunpla. This sparked his passion, leading to his first custom build, the ν Gundam Vrabe. Pressure to inherit his stepfather's company later forced him to study in London, where Gunpla was forbidden. His enthusiasm reignited after meeting Takeshi Iori, who instilled the philosophy "Gunpla is freedom," emphasizing personal creativity and enjoyment in building and battling.
At Seiho Academy, he served as student council president and modeling club captain. Recognized for exceptional building and piloting skills, he competed nationally as the "Crimson Comet," piloting the RX-93-ν2V Hi-v Gundam Vrabe – noted for emitting red light in combat – and later the MS-06R-AB Zaku Amazing. He withdrew from the 7th World Tournament qualifiers but fought an unsanctioned battle against Sei Iori and Reiji, resulting in mutual Gunpla destruction.
He then assumed the title of Meijin Kawaguchi III, historically awarded to master builders. As the third inheritor under PPSE (Plavsky Particle System Engineering), he adopted a pseudonym, dark blue coat, and sunglasses. Departing from his predecessor's win-at-all-costs approach, he championed the joy and artistry of Gunpla, viewing battles as expressions of creativity. He piloted advanced units like the PPMS-18E Kämpfer Amazing and the incomplete PPGN-001 Gundam Amazing Exia.
A pivotal moment came in his semi-final match against Julian Mackenzie, a former top student from the Gunpla Academy whom Tatsuya had never beaten. Mid-battle, he temporarily renounced the Meijin title to fight as himself, proving his resolve to redefine the legacy towards passion and freedom. Winning with the Amazing Exia's Trans-Am system, he encouraged Julian to rediscover Gunpla's inherent enjoyment.
Later, he abandoned the Meijin persona but remained active in the community, appearing in *Gundam Build Fighters Try* as a mentor and in *Gundam Build Metaverse* as a past champion within the virtual realm. His later Gunpla included the Amazing Strike Freedom and the MSM-07-A Amazing Z'Gok, featured in *Battlogue*.
His character arc concluded with a focus on fostering inclusivity in Gunpla culture, distancing himself from corporate ties while continuing to innovate in building and battling. This evolution from a constrained heir to an advocate for creative liberation reflects the core philosophy imparted by Takeshi Iori.
