Lune is a jerk. A grade A jerk. He's like his "dad" but without the sociopathy. Lune sees himself as superior to everyone. He's rather melancholic and seems pretty much emotionless. But that's only the shell, the inner layer is a mess comprised of flawed programming, his "father's" morals and views of the world, and the belief that the New Gen's are best Gen's. Just avoid Lune at all cost, it's probably better that way.
Especially with the drawn-out sentences he pulls out so frequently and generally being strange.
Physical Description Edit
Lune looks very much like his "father", down to the moon-like haircut. He's even got the yellow eyes.
