Yoken Shihōin (四楓院 夜見, Shihōin Yoken) better regarded by his title of Eizō (影像, Silhouette) among the Onmitsukidō is a member of the Shihōin Clan, older brother to Blake Shihōin and Juunan Shihōin, as well as an elite operative of the Onmitsukidō. While stationed at the boundaries of the Gotei Remnant's territory within the newly created Reikai, Yoken's eyes have been peering towards the organization and its new commander. His suspicions are made clearer from his observations of Yori Hisagi, albeit he hasn't made any movement as-of-yet, remaining an incredibly enigmatic character.
