Killian

A tall man that has an aura of evil but loves his younger brother deeply, and would kill anyone that touches a hair on his brothers head. He shows no emotion, unlike Douma (his younger brother) and would never be seen showing a fake personality. He watches each hashira carefully to ensure not one of them hurts his brother but has since developed a crush on the water pillar from watching them all so closely. If anyone asks him about his "crush" he panicks and runs to find his brother for comfort. He tries to be a good brother for douma but is rarely seen with him since he hadnt been turned into an uppermoon as well.
