Arado Balanga, designated Bronzo 28 at the clandestine Earth Federation Army facility known as The School, survived a brutal program that trained children as Personal Trooper pilots through lethal methods, advanced steroids, and growth hormones, resulting in high mortality. He emerged alongside his assigned partner Bronzo 27, later named Seolla Schweitzer, as well as Aurum 1 and Latune Subota. Instructor Cuervo Cero treated the children kindly and gave Arado and Seolla their full names after the program ended, after which Cuervo and Águila Setme continued their training within the Divine Crusaders. Arado is cheerful and rebellious, lacking military etiquette and disregarding authority, frequently arguing with Seolla and making inappropriate jokes about her physique that provoke physical retaliation. Despite this, their bond is profound, forged by a mutual promise to protect each other and survive. He possesses an extraordinary appetite, consuming three full-course meals in one sitting, and is the only person known to enjoy Kusuha Mizuha's health drinks. He also demonstrates remarkable physical resilience, recovering swiftly from injuries. As a pilot, his skills are considered subpar for a School graduate; his training emphasized paired combat, rendering him ineffective alone and heavily reliant on Seolla. He often acts carelessly in battle, leading to frequent defeats, yet exhibits bursts of exceptional prowess in critical moments, sometimes activating his Lion's Boost Drive to intercept attacks meant for Seolla, taking hits such as a rocket punch or critical vulcan fire for her. After The School's shutdown, Arado and Seolla joined the Neo Divine Crusaders. During a mission to steal the Wild Falken prototype, Arado was shot down and captured by Earth Federation forces. Waking aboard the Hagane, he reunited with Latune. Though initially attempting escape, he defected to the Earth Federation Army after defending Mao Industries' lunar base against the Inspectors, piloting a Huckebein MK II M with a makeshift hammer. His defection solidified after psychiatric evaluation by Radha Bairaban. Arado's primary motivation became rescuing Seolla, who remained with the Neo Divine Crusaders and underwent memory alteration that erased her bond with him and painted him as an enemy. Despite multiple confrontations, including one where she nearly killed him in his R-Blade, he persisted. He eventually received the Wild Wurger, a counterpart to Seolla's Wild Falken, enhanced with the Stag Beetle Crusher grappling weapon and programmed with combat data from elite pilots Kyosuke Nanbu and Katina Tarask. Ultimately, Seolla's suppressed memories resurfaced, breaking The School's control and reuniting them. Throughout his journey, Arado formed significant bonds beyond Seolla, treating Latune like a sister and aiding Shine Hausen, crown princess of Riksent, in liberating her dukedom from Neo Divine Crusaders occupation.
