(I do not own RWBY or Kamen Rider. Each series is owned by Rooster Teeth and Toei respectively.) The World of Remnant... A place containing peace... And ruin... Grimm and Demons cause chaos wherever they strike. But how does one fight Demons? With the power of Demons themselves.

During a fierce battle with a powerful Worm, Tendou Souji activates his Hyper Clock Up to deliver the final blow. But something goes wrong - a massive temporal distortion engulfs him, tearing through space and time itself. When the light fades, he finds himself standing beneath a vast blue sky, surrounded by unfamiliar terrain and the sound of a dragon's roar in the distance. He has arrived in a world known as Teyvat - a realm where gods reign, and visions grant mortals power. Confused yet calm as ever, Tendou begins walking toward the nearby city he spots on the horizon: Mondstadt. However, his arrival does not go unnoticed. The distortion from his Hyper Clock Up has drawn the attention of both the Knights of Favonius and mysterious Abyssal forces lurking in the shadows. As chaos brews, Tendou realizes that destiny has once again chosen him - to bring balance to a world not his own. Now, as Kamen Rider Kabuto, he must face new enemies, forge unlikely alliances with heroes like Lumine, Diluc, and Jean, and uncover the truth behind the Clock Up of Destiny - the link that binds his world to Teyvat.

After a fiasco that involves the alteration of the timeline in 2019, Soji Tendo finds himself in a new world. Knowing that his friends and family are able to take care of themselves in his home world, Tendo continues to walk the path fate has decided for him, even if it meant... Becoming a Sensei.
