No one really knows how Daiki Kaito became the Kamen Rider known as Diend. He seemed to know Tsukasa Kadoya (aka Kamen Rider Decade) before Tsukasa knew him, and stealing treasures is his forte. In his treasure stores are things like rare transformation belts, secret scrolls and, after many times crossing paths with Decade and Natsumi Hikari (later to be known as Kamen Rider Kiva-la), friendship.
Of course, that still doesn't stop Diend from stealing everything that's not tied down, just ask Den-O.
