I also some idea that I had in mind if you leave a common of this ideas and agreees with that idea, I'll submitted and write it.
Rise of the Shield X Kamen Rider W
Gate Jietai Kare No Chi nite, Tatakeri X Kamen Rider Drive or Agito
Cross Ange X Kamen Rider Build
Saint Seiya X Kamen Rider Saint
Pokemon X & Y X kishiryu Sentai Ryuusouger
Power Ranger Elemental Force (my creative Power Rangers)
Kamen Rider kikai X Accel World (my original plan was with Cross Agne)
Kamen Rider Ryuki X Fate Stay Night (with all of the 3 routes together)
Sorey about that, its just that I didn't have enough writings on it. Also, I'll be changing the Kamen Rider anime crossover as well.
I'll also write down the story of Kamen Rider Den-O: The Assassination Adventure soon since it will be the anniversery od this story.
but until now, please leave a common and I'll let you know about this soon. See ya later.
