However, the Kumō brothers soon learn how they are tied to the Orochi's vessel, a human host possessed by a demon serpent from ancient times, and how they are destined to destroy it once and for all.

When in combat, Tenka is known to be strong enough to defeat dozens of prisoners in an instant with nothing but a fan, as well as being quick on his feet.

He shows symptoms of being the Orochi's vessel, and is promptly prosecuted without a trial, but is later revealed to be alive under the protection of the police.

After fighting against the Orochi and Fuma ninjas (including Shirasu and his younger brother), he sustained wounds that left him requiring a wheelchair, unable to walk again.

Soramaru also struggles with the fact that he is weaker than Tenka, not being able to be recognized as a strong man who is worthy of protecting his household.

He suffers from memory loss due to the childhood trauma of witnessing his parents' murder and nearly being strangled to death.

After Tenka's alleged death, Chūtarō's disappearance and Shirasu's betrayal, Soramaru's negative feelings causes his mental state to deteriorate and he eventually turns into the real vessel of the Orochi.

After learning that Tenka was actually not the real Orochi's vessel and has died for nothing, he decides to seek revenge and leaves the Kumō Shrine with Naoto Kagami.

It is later revealed that his true that identity is the 10th head of the Fuma clan, Kotarō Fūma, and that his real objective has always been to resurrect the Orochi.

He and his younger twin brother faked the Fuma massacre then separated ten years ago in order to lie low and prepare for the return of the Orochi.

In Gaiden, it is revealed that he survived the fall and has rejoined the Fuma clan, but still has feelings of fondness for the brothers.

She first appears to be Chūtarō's schoolteacher, but is later revealed to be a Shikigami that played an important role in the sealing of the Orochi during its last awakening three hundred years ago.

The woman is later revealed to be Botan, and the reason behind his inexplicable dreams is because he is the reincarnation of a man whose fate has been tightly intertwined with hers.

At midst Orochi's awakening, Hirari remembers all about Botan and confesses his long lost love for her.

Member of the Yamainu Squad, his speciality is using magic and sorcery, including summoning Shikigamis as familiar to gain information.

The remarkable differences between him and his brother are longer hair worn in a ponytail, wearing a fox mask that hides a grievous scar on the right side of his face.

He joins his brother to awaken Orochi, but eventually their plans are frustrated by the Kumō siblings and Yamainu's progress.

He was the head of the Kumō family from 600 years ago prior to the series who, along with Abe no Hirari, helped Botan to seal the Orochi.
