"Now I Am King."
I'll play. My avatar is the emblem of KING. In Kamen Rider Kiva, there is a race of vampires which is ruled by a King and Queen respectively. King's are decided based on the crest that appears on their hand. So a King could have a couple dozen kids but only the one who has the crest will be the next King.
Taiga, also known as Kamen Rider Saga is the current King. Kamen Rider Saga is the older brother of Kamen Rider Kiva whom the show is named for. If you look at the video you can see the emblem on Taiga's hand.
My signature consists of various Nexus emblems and a quote from King himself.
