Six Shinshou

The Six Shinshou (aka Six Shou 六ノ鞘, Roku no Shou) are the strongest and most mysterious of Himeou's Shinshou. All of them wear ceremonial robes with masks to keep their identities secret. Shim is the designated leader of the Six Shou and his goal is returning his comrades back to their original world: Earth. Harunawa does the dirty work and cleans up the mess; he slaughters Himeou's successors to prevent another woman from taking over as ruler. Kikutsune is the troublemaker and loves to stir things up; he often butts heads with different members of the group. Isora is the only one wearing a mouth mask to prevent him from speaking. Not much is known about the other three yet. The other members of the Shinshou are weary of these men who they deem creepy. All information of these members was removed from records in Himeou's court to prevent others from gaining knowledge on their abilities and identities.

Later on the series,they all reveal to have lost their human hearts and turn into inhuman beasts themselves. They have demon marks around their bodies, which cause them to have the ability to transform into a formidable beast. They have their Hayagami absorb into them and unleash the Kamui from their body and became even more powerful. The first stage of their demon form is that their humanoid fighting form completely changes to become more powerful. The second stage of the demon transformation is that they change into a complete beast altogether. Kikutsune,Harunawa,and Isora have revealed their demon forms so far. Although Harunawa has stopped his first demon stage transformation.

Triva

 * Harunawa is the only Six Shou member who is not from Earth, although it clearly unknown how he is part of the Six Shinshou.
 * The Six Shinshou could possibly based on the Hayagami Code:"eyes,ears,nose,tongue,body,mind". Kikutsune lost his eardrum. Isora had his tongue cut off. Shim could be representative of the "eyes".
