Naibu Sanguis

Naibu Sanguis (Sanguis Naibu) is a Jōnin-ranked Shinobi of Hoshigakure and a former bodyguard to the Hoshikage. He is famous throughout the Land of Bears as the Blood Promise for his mastery in his Clan's Kekkei Genkai.

Appearance
Naibu, although only in his late twenties, has been noted to appear older; with Gray once commenting that he hasn't aged well. He has sharp facial features, rarely smiles and has a pointed chin with a piercing green gaze. His clothing consists of a loose fitting black kimono instead of the usual Shinobi attire with a sword resting at his waist. His hair is neck-length and red in color, bearing a close similarity with that of Gray Kazuki. Around his neck he wears a beaded green necklace and wears his forehead protector wrapped tightly around the sheath of his sword.

Behind the Scenes
The name Naibu Sanguis is a combination of Japanese and Latin. In Japanese, Naibu can be translated as inner, while Sanguis in Latin is blood. Coming together as Inner Blood, the name itself is an allude to his Clan's Kekkei Genkai, the Chi Sōsa.
