Shu Shirakawa is a highly intelligent individual who conducts himself in an extremely proper manner. Despite this propriety, he has been known to condescend his enemies for their perceived weaknesses. Although Shu comes from La Gias, where alchemies and magics are highly developed, he was able to quickly adapt to Earth science and even combined it with these practices. He is an excellent alchemist and possesses a high amount of mana, surpassing even Prince Palelord. Despite coming to this world and working with DC, Shu later became the pilot of Granzon and helped defeat the remnants of DC and Inspectors. After Bians death, his motives remain unknown. He has been involved in several battles and is constantly being pursued by Masaki, his arch-enemy. Shu values his freedom and hates being controlled by others.
