Kyle is from a visual novel called Lost Alice.

Kyle's role in Wonderland is the "Chesire Cat." His duty is to guide Alice, and if she ends up trying to escape from Wonderland, he is supposed to lead her astray, making sure that she does not leave their world. Kyle is very flirtatious and loving towards Alice, not wanting to let her go when he first meets her. He is also very protective of her and in other routes, does not let her escape Wonderland.  In his route, he feels guilty for trying to trap Alice in their world, and they both agree to try and flee to the "real world" together. Kyle is also very playful and michevious, occasionally going against the rules of Wonderland. When he does this, he says the opposite of what he wishes to say, so that it isn't technically breaking the rules of Wonderland. 

Voice: Smooth, silky, deep, slightly gruff, and seductive. His voice can be very playful sounding at times. We are looking for a voice similar to the previous Voice Actor
