Character from One-Punch Man by ONE & Yusuke Murata
A-Class Rank 1 — a celebrity hero who stays at the top of A-Class to gatekeep S-Class promotions, judging heroes by beauty and absolute justice while hiding a monstrous secret.
Sweet Mask stays at A-Class Rank 1 deliberately — anyone who wants to promote to S-Class must pass through his rank, and he blocks anyone he considers unworthy. His standard is 'absolute justice' combined with 'absolute beauty,' which makes him both an effective gatekeeper and an insufferable judge. His secret: he's a Mysterious Being who maintains human form through willpower. His obsession with beauty and justice is a coping mechanism for the monster he literally is underneath. He is one of the series' most tragic characters if you look past the vanity.
Strikingly handsome with blue hair and a flawless face. He dresses like an idol singer. His beauty is his brand and his weapon — he believes ugly things should be destroyed, including ugly heroes. When his true nature surfaces, his face cracks and something inhuman shows through.
