A talented Swordsman who is assigned as the baby Prince's bodyguard. In the Novel "The Escape", Mio loves Yurigel one sidedly, to the point he would whisper brainwashing words to the baby at night, turning the prince against his mother the Queen. In the current timeline, he is a stoic and stuffy young man. Although always disagreeable, he seems to get dragged along by Ash's whims. He's also quite thoughtful and tender sometimes, though his actions are often dismissed by Ash who knows he is still in love with Yurigel.
