Is there anything you need us to KNOW about interacting with this character?:
YES! Please please read this -- Whenever a girl hugs him, he transforms into an orange cat, as... you can see in the icons.
This is one of the reasons he's uncomfortable with girls or large crowds of people in general. It also means he has a bond with cats, so for you catgirls/-boys, you'll probably feel a connection -- he tends to attract cats to him, as well.
He also has a red-and-white (or black-and-white) bracelet on his left arm, which is a;djfld;ghdl;fjds SUPER IMPORTANT. If it's taken off on rainy days, he transforms into his second form, a hideous, vaguely bunny-like monster that smells like rotting flesh. (
...Also, for those of you familiar with Furuba -- despite a few anime icons, this is MANGA KYO, and he's taken from after that Summer Beach House arc.
Oh! And for the psychics -- Kyo is human, but within his body is the very, very old spirit of a cat (or rather, THE cat aha). It's not... evil, precisely, but it's definitely not a friendly thing, either. It also can't think or communicate or anything like that, and for the most part, is just a presence. It sometimes shows emotion, though! Like, it hates bodies of water and rainy days, and those things affect Kyo's moods and physical well-being, but it really only has power over Kyo.
