Age: 600–700 years old

Origin: Snezhnaya (due to being from a very cold region, they do not exhale white breath in places like Dragonspine)
Personality: A gentleman but black-hearted; enjoys reading the room and making sarcastic remarks, or praising someone repeatedly until they get carried away, then observing their reactions. Calm, never cries or gets angry. Has a somewhat lone-wolf tendency, which can cause misunderstandings among those who don't know Frinz well.

Strength: Having lived for 600 years, they are generally strong.
Appearance: Long navy blue hair reaching about waist-length, with the tips slightly white; M-shaped bangs. Eyes are moon-like yellow with no highlights, with slight dark circles under the eyes and a small amount of black eyeshadow. Clothing is predominantly black, covering the Fae emblem and several birthmark-like shards of glass on the body; skin is barely visible. Wears a black jacket-like long-sleeved top and black long pants.
Height: 186–190 cm
Dislikes: Plain water
Likes: High-alcohol liquor; can drink spirits that would make a light drinker instantly drunk without changing their expression. Also enjoys shiny collections and gems, spending almost their entire salary on them. (In their own way, they are enjoying their current life.)
Speech: Uses polite language like "○○ desu ne" (〇〇ですね) or "○○ desu ka" (〇〇ですか), but thinks in casual speech—e.g., "(I probably can't do that.)" (僕には無理そうだな). When alone, they speak more bluntly, like "Wrong person... disappear." (人違いだ…消えたまえ).
