Anime Crossover: Living with Spirits and Wandering Through Other Worlds

One day in the future, someone with sinister intentions shatters the history of Kamen Rider. To erase the Kamen Riders from existence, he scatters the Ridewatches that represent their history across different worlds. When a Ridewatch activates, the history of Kamen Rider begins to encroach on that world. In the end, that world's destruction will erase that history of the Riders. At the same time, a young man's journey begins. As another Decade, he will return to write his own story. Except the tone seems a little off? What do you mean, you gave Mordred four Command Spells and let her take a Signal Axe to chop down Artoria? You fed the old director his favorite Origin Bullet? You seem to have met every Spirit? You played tennis with Tokisaki Kurumi and nearly blew up the court? Why is Shirou Emiya holding Ryuki's Village Good Sword? Why has history gone off course in the Date A Live world? To answer that, I'd like to interview the characters. What do you think of Kadoya Tsukasa? Mordred: He called me king! He even gave me a Signal Axe, a weapon made for killing my father. What else is there to say? Let's do this! Artoria: I hate him, but his cooking is delicious. Jeanne: He always bullies me, but the Lord wants me to keep my eyes on him. Yukino Yukinoshita: Sharp-tongued, but somehow attractive. (Flustered.) Haruno Yukinoshita: I need to keep him right under my nose. Too bad he doesn't seem to like me. The Spirits: He's very important to us. Mio: Koda is the most important person to me. Tokisaki Kurumi: Ara ara, I really want to devour Koda. Illya and Itsuka Kotori: Boo-hoo, we were here first! A crossover of anime, Date A Live, Fate, Carnival Phantasm, My Teen Romantic Comedy SNAFU, Kaguya-sama: Love Is War, Oshi no Ko, and other slice-of-life series.
