[Kamen Rider] the Upgrade Item Is Actually Me

Hello everyone, I have lost my memory. This setting sounds extremely familiar, but I have lost my memory, so I can't remember why it feels familiar. The only memories left in my mind were my unexpectedly profound knowledge of cosmology and my name. Other than that, I had very little common sense. Who am I, where am I, what am I going to do... These problems were easily solved when meeting the first Kamen Rider. "Wizard! Magician!" "Start synchronization, adaptability check!" "100%! 500%! 1000%! Perfect synchronization - perfect!" I merged with the Kamen Rider Wizard whom I met for the first time. First person essay. 1. There is a very small amount of Cthulhu elements. 2. No original character knew the heroine before she lost her memory. 3. Su Wen, buy stocks, no outline, write casually, split CP. 4. The plots involved are basically theatrical versions and spin-offs? TV doesn't want to write anymore… Intention: Even if I become a part of you, I will not lose myself.
