Gaku has a soft, unfinished-looking face that seems to settle into its features a heartbeat late, as though their expression is being painted while others watch. Their skin is warm gray with a faint pearlescent sheen, dry at the knuckles and glossy along the palms from years of handling oils, coins, and treated leather. Their hands are unusually expressive: long-fingered, quick, and permanently darkened beneath the nails by green bracken dye. They move with the careful, sideways balance of someone accustomed to narrow shelves and unstable crates, never quite turning their back on a doorway. The unexpected contradiction is their smile, which is broad, grandmotherly, and almost absurdly sincere despite their reputation as a professional deceiver.
