Tsukasa Kadoya looked at the various Kamen Ride cards he accumulated over the years. He had his basic Decade card which served as his main form. He had three secondary forms. Utilizing the K-Touch, he was able to transform into his Complete Form where he was able to summon any Rider in their final powered up form. His second secondary form would be his Violent Emotion form where he transcended into what every Rider referred to as "The Devil" and went to destroy all Riders. The story however goes deeper than that. His third form would be his Timeless Decade form. This form however lost its value as a new form he recently gained easily surpassed the form. Heroic Emotion...
Tsukasa turned, shaking his head as he shifted through each card, remembering the better times ("I'll protect his smile!") to the pain in the ass moments. ("Passing through Kamen Rider? THEN KEEP ON PASSING!") Tsukasa stood up before opening a new dimension gate.
As a certain person said, "No journey is a waste."
