Luxun (Rikuson) Zeta Plus is a young soldier and a disciple of Shuuyu Hyakushiki in SD Gundam Sangokuden Brave Battle Warriors. Orphaned during Toutaku Zaku’s oppressive reign when his entire village was destroyed, he was rescued by Sonshoukou Gerbera and the Sun army after being harassed by pirates. Sonshoukou invited him to join her family, which he gladly accepted. Inspired by witnessing Shuuyu’s stratagem repel Kirei Hamma Hamma, Luxun decided to become Shuuyu’s student. He serves as a close companion to Sonshoukou, often acting as her caretaker and enduring her playful mistreatment. During the Battle of Red Cliff, after Shuuyu was severely injured in an attack by the Keishuu troops, Luxun took command of the Koutou Navy. Following the battle, he succeeded the fallen Shuuyu, inheriting his position and responsibilities. His subordinate is Teiho. Luxun wields a large spear with great skill and carries the Hientate (Flying Swallow Shield) as his weapon. He is characterized by the epithet “the dancing wings of tomorrow,” reflecting his potential and growth from a displaced orphan into a capable military commander loyal to the Sun faction.
