Quincy is a character from the game Nu: Carnival, voiced by Oshima Tetsu.
Official description from the game’s website:

Possessing a huge amount of essence, Quincy has been marked as a dangerous existence by the forest tribes. He lives in solitude out in the wilderness, with only the little, furry pet on his shoulder to keep him company. Not one for conversation, he hates being troubled and spends far more time sleeping than the average person.
