Mask is a light-skinned Inkling boy with droopy eyes and a hunched back. His attire consists of a Gas Mask, a Purple Camo LS, and Green Rain Boots. His main weapon is the Carbon Roller Deco, and his rank is S+. He is quite nihilistic, and despises 'happy people', vowing to destroy all Inklings who enjoy life. He takes pleasure in playing Squid Beatz and Salmon Run shifts. His team's Co-Captain is an Inkling Girl named Full-Moon Glasses. He also has hayfever but is fine with his Gas Mask on.
