Kage

Kage (カゲ) is a member of the Shadow Clan and Prince Bojji's friend/bodyguard.

Appearance
Kage appears to be a small black puddle with two slanted, blue eyes. He has two arms that disappear into his body when unused, and a third arm that serves as a mouth.

Plot
Kage is the last surviving member of the Shadow Clan, an infamous clan of assassins who were annihilated in a purge when Kage was a small child. Forced to flee, Kage was openly-scorned by the residents of the towns he visited, until he was found and taken-in by a local thief.

The thief used Kage's strange body to commit dozens of robberies, and eventually sold him out to the kingdom's forces for the reward. Through sheer luck Kage was once again able to flee, and traveled the countryside as a thief and a robber, until he eventually ended up on the outskirts of the Bosse Kingdom, where he first met Prince Bojji.

After an encounter with Bebin, Kage was appointed to be Bojji's secret bodyguard, and remains one of Bojji's closest allies on his journeys.

Personality
After years of uncertainty and abuse Kage developed a very rough exterior, pretending to be a hard-bitten thief who wouldn't think twice about killing someone. In reality Kage is empathetic and kind-hearted, and quickly dropped his pretense around Bojji once he realized the young prince's circumstances.

Kage is much more worldly and savvy than Bojji, and tends to act as both the voice of reason and resident skeptic on their adventures.

Abilities
Kage is a member of the Shadow clan, an infamous clan of assassins with inhuman, flat, almost fluid-like bodies. His dark body is able to move quickly and silently across nearly all surfaces, including vertically up and down walls. Presumably this talent helped the Shadow clan sneak into buildings to commit assassinations.

He has two arms that can apparently retract completely into his body when not in use, and protrude from wherever he pleases. Kage also has a third arm that typically protrudes from the top of his head, and eminates sound from a crude mouth.

Additionally, Kage is able to store items that are larger than himself within his body. How he does this is unknown.

In spite of all of the above, Kage is a human being. Kage's strange anatomy is apparently the result of a curse placed on everyone in his bloodline. This curse is rumored to be for an ancient offense against the gods.

Kage has some skill with knives, either from early training in the Shadow clan or due to his time spent living with a thief. He armed himself with a knife upon first meeting Bojji, and he can accurately use the throwing knives given to him by Bebin.
