Shugen was very dignified and diligent in his duties as an executioner and took great pride in being an Asaemon. He cared greatly for his Yamada clansmen, having spent his years with them and being taught what they know, which was reflected in his abilities. He greatly expressed his concern for their safety on the island and vowed to bring them back home no matter what the means were. Furthermore, Shugen had a tendency to become emotional whenever he thought about his comrades.
