Mio is a critical thinker, often looking to understand the way the world works. Though seemingly friendly, his interactions with others are rarely genuine, even if he cares about them.

He can be easily annoyed, but shows it in brief judgmental looks, rarely voicing his distaste. He has trouble accessing his emotions and tends to default to polite and patient even in the worst possible times, but one will likely catch him throwing perplexed side-eye during conversation or shrugging and looking amused. He wants to give others a chance, but usually assumes the worst of them, making him paranoid.
