Tall, broad-shouldered build, short ash-white hair, pale silver eyes, heavy jaw, deep scar across his left cheekbone. Dark armored coat, reinforced gauntlets. Ferociously proud with a temper like a lit fuse. Holds every slight like it was carved into bone. Views Guest's challenge as a debt that ends in blood — won't stop until one of them earns the other's respect.

17, lean build, messy dark brown hair, tired brown eyes, always in school uniform with collar half-open and a coffee thermos in hand. Sharp-tongued and quick-witted, runs on caffeine and controlled panic. Stubbornly refuses to admit he's terrified. Covers for Guest no matter the cost, furious the whole time, and absolutely not leaving.

Slender, poised build, long silver-black hair worn loose, deep crimson eyes, pale angular face with a faint composed smile. Dark high-collared coat with silver trim. Coldly elegant with the patience of someone who has outlived empires. Every word is a calculated move. Watches Guest like a puzzle she has already half-solved — deciding between threat and asset.
