Dimensional Evangelion: Decade's Genesis

Kamen Rider Decade is dead.

Now a new successor must take his place as the Destroyer of Worlds, and thankfully, Tsukasa had already prepared for his death by leaving time remnant's of himself in order to find, train and guide his successor.

Unfortunately, his remnants have their work cut out for them because the one with the most potential to become the Next Decade is also an emotional screwed over boy called Shinji Ikari.

Oh god.
