Upon waking, Nobita finds himself sixty years behind in technology. In the town of Tsukimidai, all memories of Doraemon vanish along with the regressed era. After a series of twists and turns, Nobita and his friends learn the truth: an unprecedented, massive, and trans-temporal war is unfolding, its target the future where humanity's technology is booming. The dominoes hidden in the past have already fallen, about to form a colossal wave that will engulf every era of humanity. The only clue is a snapshot taken across time. On September 19, 1492, at the center of the temporal vortex, the Time Police captured a photograph of the back of a blue nursing cat-shaped robot. This becomes the catalyst for Nobita and his friends being drawn into this trans-temporal heist. As they uncover more and more clues across different eras, a massive conspiracy gradually surfaces.

If you were given superhuman strength, what kind of person would you be? Anluo's answer was: Day 1, I'm Superman! Day 2, I'm Happy Superman! Day 3, I'm Happy Superman Too! Having transmigrated to a crossover anime world, he gained the cheat ability to quickly become stronger by indulging his desires. At first, Anluo thought he was quite restrained, at least he didn't say "I don't eat beef." But soon! Anluo realized he had overestimated the high-end combat power of this crossover world. What kind of order was this? What kind of romance was this? He'd force them together first and then cultivate feelings! To recreate Slaanesh's glory, I have no choice but to do it. Yotsuya Miko, after rescuing the beauty, I must repay her with my body! Sakayanagi Arisu is so small, so sweet, let's fight! Futaba Rio has a split personality, launching a mixed doubles attack, let's fight! This world is so wonderful! What? I can also transmigrate to other worlds? That's amazing! In another world, I'll travel with Elena, kick the God of War from No Game No Life, and punch the god of humanity from Mushoku Tensei…

[Slice of life across various anime series, multiple heroines, gradual romance, not mindless gameplay]

Taki Aragaki also likes rainy days, and the same rainy weather rewards him with different precious things, but it seems that there is more than one such precious thing.

So you're from the future?

Looking at the somewhat childish handwriting on the paper, he just found it a little funny. He guessed it was a joke played by the child who couldn't find his way home. But it wasn't until the other person clearly stated his information that he believed that perhaps his life had really undergone some incredible changes.

"So should I just follow what's going to happen in the future?"

"But besides that, it seems there are other things I need to take care of..."

Looking at the timid blonde loli in front of him, the boy thought to himself.

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.
