Sick

""All those that posses life want to live. That is why I conduct. [...] Aah, God. Truly I am the one and only rule that makes this world turn so beautifully.""

Sick (シック) is the UMA that embodies sickness. He is also known as the "Tenth Master Rule UMA". He serves as the main antagonist of the Sick Arc.

Appearance
Sick takes on the appearance of a human with a slender but tall and fit build. Being the Tenth Master Rule, Sick has an X on his chest signifying his ranking within the Master Rules. He wears long pants with zippers running down each pant leg that have belts around them. He has long black hair that reaches down to his hips and his face is absent of eyebrows.

Personality
He has something of a "conductor" personality, seeing the agony of humans infected by his powers as "music", and believes himself to be the only rule capably of letting this world turn beautifully by culling humanity. He also seems to care mostly for confronting the "first seat", given his sudden depression when Fuuko ignores him before getting back up by stating they're so "commonplace" that its why she's ignoring him.

Abilities
