Six Shinshou

The Six Shinshou (aka Six Shou 六ノ鞘, Roku no Shou) are the strongest and most mysterious of the Twelve Shinshou. All of them wear ceremonial robes and masks (except have their own symbols on them) to keep their identities secret. All information of these members was removed from records in Himeou's court to prevent others from gaining knowledge on their abilities and identities. Therefore the other Shinshou members are weary of these members who they deem creepy and strange. Shim is the designated leader of the Six Shinshou. Five out of six members (Harunawa) ambitions are to return back to their original world: Earth. With few of the members's identity and backstory revealed, it may confirmed that all of six members had lost their senses such as hearing or seeing.

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.
