Mulin, who was rescued by the system under certain conditions, was reincarnated into a crossover anime world.

In order to shed his heavy past experiences and with curiosity about the new world, he changed himself and started living a new life with the unbridled mentality of a free-spirited idiot.

I thought that everyday life would always be with me.

Until the crisis is about to strike the person you care about...

"I'm sorry, host, due to your clothing, your body..."

Hakuhana, a Kamen Rider, joins the school idol club.

The original Kamen Rider series features a lot of slice-of-life scenes, with very little or no screen time for the male protagonist from the original work. The introduction of supernatural beings is primarily to better facilitate the emotional development of the relationship. This is also my first time writing something like this, so please feel free to point out any issues.

Oregairu, Mob, Love Live! Starship Troupe, Chuunibyou, The Quintessential Quintuplets (and later), etc. If you have other titles you'd like to add, please suggest them.

The knight from the future, Hyakka, uses various flowers in battle. During his battle with Oma Zi-O, he fell into a time rift and arrived in a new world. His power of Hyakka also scattered throughout this world.

One day in the future, the history of the knights is scattered by someone with ulterior motives. To destroy the knights' existence, they disperse the watch face representing that history across various worlds. With each watch activated, that piece of knightly history begins to erode that world, ultimately erasing it at the cost of an entire world. Meanwhile, a mysterious young man named Kadoya arrives in Shuchiin. What is his true identity? His mission to collect knightly history across 38 worlds is nearing completion, and he will soon find the meaning of his journey.

Currently in the world: Fate (Rider Rush+). When the Holy Grail War in Fuyuki City unexpectedly intertwines with the Knight War in the Mirror World, an unusual Holy Grail War of fourteen knights in a chaotic battle quietly begins. Magicians and Kamen Riders, Contract Beasts and Servants, the Mirror World and the real world—the originally parallel laws collide here, bringing chaos and miracles.

Kamen Rider + Fate + Oregairu + Date A Live + Kaguya-sama: Love Is War + My Favorite + Ellie-chan... and so on and so forth.
