Sirius is a young woman with smart blue eyes, sloping inwards, and short, shoulder-length hair of a lighter blue color in which she wears side swept to the right.

Her hero costume consists of a sleeveless white sailor uniform with a dark blue, double-trimmed collar and a short 3-piece skirt which is buttoned together on either side. She wears a loosely-tied red scarf and blue gloves with white striped wrist guards, and on her feet, thigh-high boots with wavy lines running down them from thigh to toe. She sports a flat hat with a ribbon around the base and two large communication devices on her ears to aid with the use of her Quirk, which are shaped like large, blue fins.

Sirius appears to be a generally friendly individual who was keen on teaching Tsuyu Asui the importance of becoming a hero. She is highly respectful of her Captain, although she is constantly embarrassed by his attempts to look cute. Sirius is selfless and would have rather been killed by Innsmouth than allow him to escape.

Sirius can understand Morse code, having received and interpreted coded messages from Selkie using his Quirk.

Sirius' Quirk allows her to hear high frequencies and quiet sounds that normal people cannot. This allows her to communicate with Selkie, even when they are far distances apart.

Earpieces: Sirius always wears a fin-shaped Earpieces that she uses in combination with her Quirk to communicate with her teammates.

Steel Baton: Sirius carries with her a retractable steel baton that she uses when she has to engage battle. She hides the weapon in her clothes so she can attack by surprise.
