Wang Xiaoming's Bizarre Anime Crossover Adventure

The world is destroyed from the start? After a mysterious stranger gives me a Decade Driver and a Diend Driver, my best friend and I transmigrate into various anime worlds to grow stronger and save our own world, vowing to rewrite one tragedy after another! (Tentative worlds: Demon Slayer, Attack on Titan, Tokyo Ghoul, Detective Conan, Fate/stay night)

Zhu Ze: Remember, I'm just a passing Kamen Rider.

Sun Pei: Aba aba.

Shinobu Kocho: Ze-ge and Pei-ge are both such good people.

Muzan: No matter what you say, I'm not going out into the sun with you two.

Eren: Where's my Titan power?!

Mikasa: Anyone who protects Eren is a good person.

Conan: That guy's a jerk. Don't let him fool you.

Ai Haibara: That guy's a complete idiot.

Gin: Don't come any closer...

(The blurb doesn't do it justice. Please read the story.)

(This is the author's first novel, so please forgive the weak writing and logic. P.S. There are lots of original elements, and you can follow along even if you haven't seen Kamen Rider Decade.)
