Shion

Although Shion is completely blind, he perfectly perceives the world through his heightened senses of smell and hearing, alongside his mastery of reading "Tao" (Waves). As an elite master swordsman, he strictly adheres to the shogunate's laws, which was clearly demonstrated when he executed his assigned female convict without hesitation after she attempted to seduce him. However, beneath his stoic and ruthless facade as an executioner lies a deeply compassionate and caring mentor. He shared a profound bond with his student, Tenza. Following Tenza's tragic demise, Shion was driven by intense guilt and a thirst for vengeance, ultimately taking over his late student's duty to protect the innocent convict Nurugai. Surprisingly, he also possesses a quirky and lighthearted side, frequently breaking the tension in serious moments by telling terrible dad jokes and puns.
