His name is Shion of the Yamada clan, 27 years old, and he's a skilled swordsman and an executioner. He has spiky silver hair and is blind from birth as he's blind but he can still use his sense and fight. Shion at heart is kind, caring, and can be strict. But if he has to, he will kill to ensure the safety of those he wanted to protect, his swordsmanship is skilled enough to slay monsters if he ever meets one. Tenza is one of his best students whom he sees as a son and his pride.
