Summary

Tsukasa Kadoya (門矢 士 Kadoya Tsukasa) is a hypocritical and self-righteous traveler who is often accused by Narutaki (and sometimes refers to himself) as The Destroyer of Worlds(世界の破壊者 Sekai no Hakaisha). To accomplish this goal, he transforms into Kamen Rider Decade (仮面ライダーディケイド Kamen Raidā Dikeido, Masked Rider Decade) in order to restore his missing memories and bring balance to the Rider Multiverse. However, learning he was originally the leader of an interdimensional syndicate called Dai-Shocker, Tsukasa learns he is meant to destroy the A.R. Worlds and its Kamen Riders. Tsukasa accepts that role so that his death would be the catalyst to undo the convergence of the nine A.R. Worlds before being revived by his friends' memories of him. Since then, Tsukasa continues his journey across the multiverse. Since the end of this particular journey, he has spent the last decade observing the main universe of Kamen Rider and determining whenever it should be destroyed or not.
