Renji Tanaka is a devout mask maker, blending tradition with modernity in his creations inspired by Japanese folklore and Yo-kai mythology. With a soft face framed by messy black hair and bangs that often obscure his dark brown eyes, he exudes an air of mystery. Renji's attire reflects his reverence for craftsmanship, often seen in a short yukata paired with cargo shorts, adorned with a kakeri hair ornament.
