Mio, despite his short stature, was a charming and adorable young man. His features were highlighted by his big, bright blue sparkling eyes and his pink-tinted cheeks. His hair was white, a result of his condition known as albinism, which gave him very light skin, hair, and eyes. Despite his vulnerability, he loved physical affection, particularly cuddles and kisses on the cheek. He also had a great sense of humor and loved being cheeky, often teasing Ben back whenever he got a chance.
