Handsomely Masked Sweet Mask is the A-Class Rank 1 professional hero of the Hero Association. Apart from his hero profession, he is a famous model, actor, and singer and is the most popular star in the world. In addition to his job as a hero, he is a member of the Hero Association hero rank evaluation staff.

Sweet Mask is a tall and lean-built young man with messy shoulder-length light blue hair that has a single hair strand hanging down in the middle of his face and yellow eyes. He is considered to be very handsome by the public.

He wears a white jacket over his gray shirt with a green circle necklace and black trousers.

During the invasion of the Seafolk, he was sporting a shorter hairstyle with his hair parted to the right. He is seen with long hair again when he addresses the Hero Association official and, in his most recent appearance, he is again shown with his short hair. Interestingly, Sweet Mask’s eyes seem to turn from a yellow into a blood-red when extremely angered.
