Touya

Touya is one of the Shichisei; a tall character dressed properly in a white suit, with his head compromised of five balloons (the red one with six eyes being the "face"). His method of attacking is by exposing people's happiness and making it grow; he attaches a semi-invisible balloon by a person's neck to act as a container for their happiness, sending them into a daze and, if Touya wishes it so, makes them able to infect others the same way. The balloon then grows larger as the person experiences more happiness, and eventually pops, disclosing a hideous beast that devours the person in question. Touya is also able to levitate and teleport in balloon form, and when he speaks his voice sounds like it's been put through a sound distorter.
