His motivations in life are justice, friendship, and Victory, and his hobby is reforming the world. He is nicknamed the "Reformer General" and is well-liked by the people. When he was called Sennari Shogun, there are many anecdotes about him in various places, such as "he became the 'Daishogun'" and "he became the 'Shinshogun'". However, because his name became too well-known to the public, he was targeted by the New Dark Army and was fitted with the Beheading Mask, a brainwashing mask that implants evil thoughts in people. He stands in the way of the Choshoguns as an assassin for the New Dark Army, but is rescued by Sennari's guardian beast, Red Butler, Bakuryu, and Tettora. At first, he was controlled by the enemy, so a flashing crystal was attached to Retsudou Matora, but when he combined with Retsudou Matora, he awakened as one of the Choshoguns, Sennari Gundam.
