Nanami's big brother. Though he was once a Gunpla builder good enough to appear in the World Tournament, a certain incident led to his retirement from Gunpla Battle. The efforts of Riku and his friends touch Koichi's heart, and he decides to make his comeback as a member of their force.


The Gunpla Force Battle Tournament is a big event held in GBN once per year. Competing in the final round are Avalon, led by the champion Kyoya Kujo, and the elite 7th Panzer Division led by the cunning Rommel. Starting with Kyoya's Gundam AGE II Magnum, a variety of Gunpla take to the field to determine which is the strongest force!<br>
