Yamato Bouichirou

Yamato Bouichirou serves as the central villain, driven by a complex history with the school's principal. Though he was once an ally during their shared battle against the Demon King, his shifting loyalties turned him into a dangerous opponent. He relies on his signature "Hudgson" technique, a swordsmanship style characterized by strikes so fast that enemies are sliced before they can react. This lethal precision, paired with a strategic mind, defines his rise as an antagonist.
