能力 : Tochiro has been called a genius with no bounds for his feats in engineering. Having started from the smallest and most humble of tools and antique engines, Tochiro had a fondness for classic levers and buttons as well as old style ships, implementing a galleon-like port on the Arcadia. His talents were so impressive he created a habitable zone within an asteroid with a body of water inside with the area functioning like a beach all while giving it the ability to move on a fixed course with the Arcadia. Tochiro was no slouch when it came to gunsmithing either as he developed some of the most powerful handguns in the known galaxy, the Cosmo Dragoon, a deadly weapon that can even destroy a person with a Machine Body in one shot. The technology that Tochiro developed is considered so advanced that many people thought it was impossible for someone who lived in poverty to create something that even Earth's militaries cannot replicate. This is best shown when Tochiro, before his body died out, transferred his consciousness into the Arcadia itself. It was even stated that Tochiro is one of the smartest people in the Leijiverse, with his intelligence comparable to Dr. Sananda, Dr. Adachi, Dr. Amenomori, and even Dr. Ban. Tochiro's fighting abilities were somewhat hindered due to possessing myopia as well as his small body, making him unable to use guns at long range. At close range however, he was very powerful particularly with the Gravity Saber as either a melee or ranged weapon. In fact he was one of the very few people to equal Emeraldas in combat.
