Shadow clan

The Shadow clan is an infamous clan of assassins in Ousama Ranking with inhuman, flat, almost fluid-like bodies. Kage is currently the last known surviving member of this clan.

History
The Shadow clan were a bloodline of humans at one time who, according to Kage's mother, were cursed due to an ancient offense against the gods.

Sometime in the past, the Shadow clan came to live in the Kingdom of Bo, with their members swearing loyalty to the King. This would continue until the attempted assassination of King Bo, wherein the Light clan would be mobilized to begin massacring the Shadow clan. Besides Kage, it is currently believed that no other Shadow clan members survived.

Cursed Bodies
Shadow clan members possess inhuman, flat, almost fluid-like bodies that blend into shadows and darkness. This allows them to move quickly and silently across nearly all surfaces, including vertically up and down walls and underneath doors. Presumably this talent is what helped the Shadow clan sneak into buildings to commit assassinations. They also appear to be able to heal themselves fully and fairly quickly compared to other creatures.

From what has been observed so far, each Shadow clan member has two arms that can retract completely into their bodies when not in use. They also possess a third arm that typically protrudes from the top of their heads, and can emanate sound from a crude mouth as well as consume food. Shadow clan members are also able to store items that are larger than themselves within their bodies using this third arm.

The one weakness the Shadow clan so far has is the Light clan's magic, White, which casts illuminating light in all directions. This deprives Shadow clan members anywhere to hide, and makes them easy to spot. Whether the Light clan possess other magic that also affects the Shadow clan is unknown.

Unshakable Loyalty
Supposedly, according to Bebin when first confronting and attempting to capture Kage, it is rumored that when a Shadow clan member swears their loyalty to someone, they never betray them. This reputation has since been harmed by the rumors that the Shadow clan attempted to assassinate King Bo, though it is hinted this may be a lie created by Geslan of the Light clan.

Enraged State
When a Shadow clan member witnesses the one they swear loyalty to under attack and potentially at death's door, they appear to have an ability that triggers. This ability allows them to grow exponentially in size, to the point where they can consume another living creature. This may also explain how they are able to store multiple items in their stomachs. Currently, only Kage has demonstrated this ability during Bojji's fight with Ouken.
