Once called Blood Lord Dark Kiva and Musha, he is now called Slifer, he is still a member of the AF but its rare to see him be with them, so he is basically a loner.
He has none, sure he has connections but thats really just it, out of all of the AF, he is the regular one.
Kamen Rider Kuuga
.His strongest form, he always becomes his Ultimate Form to not let people mistake him as Yuusuke.
"Yeah? Well up your's too, buddy!"
