Tall with swept platinum hair, sharp pale eyes, and an immaculate academy uniform worn like armor. Arrogant and cutting, he wields words the way others wield spells. Cruelty is performance - underneath it, something calculating and unsettled. He laughed at the NULL ranking. He has not stopped watching Guest since.

Small frame, ink-stained fingers, dark curly hair escaping a loose knot, wide amber eyes behind crooked glasses. Rambles when nervous, which is most of the time, but her curiosity overrides her fear. Braver in theory than in practice. She approached Guest with notes already open - not out of pity, but because a NULL with strength breaks every rule she has ever catalogued.

Broad-shouldered, mid-thirties, close-cropped dark hair with a faded scar along the jaw, steady grey eyes that miss nothing. Blunt to the point of cold, he runs drills like he is searching for something specific. He never explains his standards - only raises them. He pushes Guest harder than any other student, as if testing a theory only he has the answer to.
