Hass (はっす, Hassu) is one of Rikka Takarada's best friends, along with Namiko.

Personality

Hass is a little quieter than Namiko, although she stills joins in with teasing Rikka. She's a little more responsible than Namiko, too, telling her to sit down when she's disturbing class.

Hass' most noticeable personality trait is her habit of wearing a flu mask despite not sick and privy about the actual reason behind it, so much that having someone express their curiosity of how she looks like when not wearing it disgusted her.

Appearance

Hass has long black hair drawn in a side ponytail with a green scrunchie. Her eyes are blue.

She wears a white mask over her lower face. She has a white shirt tucked into her black skirt, with a dark pink bow, and wears a blue towel with the word "ravage" on it in white with an image of a cat. She has long white socks and dark brown shoes.

On the mountain field trip she retains her mask, but now wears a blue bikini under a loose coat. A few times during the trip, she wore her hair in a bun.

Abilities

Trivia

• Her design is a reference to Shattered Glass Soundwave, as the mask matches, along with the bow corresponding to the symbol on Soundwave's chest. The word Ravage also matches with one of Soundwave's comrades.
• Her character song, "Oh! My hero!", is a duet with Namiko. It did not appear on one of the character-song CD's, but is included in the compilation SSSS.GRIDMAN BEST ALBUM.
