(Comprehensive anime + system + time travel + immortality)

[Ding, congratulations to the host for obtaining the Twelve Trial System! ]

[This system grants the host twelve resurrection opportunities, and each resurrection grants corresponding death resistance!]

[If death resistance reaches 100%, you will be completely immune to corresponding attacks and damage! ]

[The number of resurrections in this system will be refreshed at 0:00 am every day. Please use it with caution! ]

[The system has other functions, please read the instruction manual for details! ]

The ruins of the labyrinth, silent for countless ages, welcomed a new master. Niu Kun, heir to the throne of Bull Demon King and Lord of Beasts, pushed open a massive bronze gate leading to countless otherworlds and dimensions. "Huh? Why are all these otherworlds from anime I've seen before?" Niu Kun then wreaked havoc in the corpse-filled world of Apocalypse, transformed himself into the King of Monsters in the ordinary yet extraordinary world of mixed anime, became emperor in the war-torn world of Zan Akagi, and served as a demon god in the high school world of demons and angels...

My name is Imazumi Rinnaeus, and I'm a transmigrator.

As a transmigrator, I naturally came equipped with a golden finger system.

My system is called the Dream Performance System. As long as I complete performances according to the script, I can receive rewards in the form of "tags."

Those max-level attributes, talents, skills, and even tags for health and longevity look truly enticing.

However, this damn system took over a decade just to activate, and the first script it gave me left me speechless.

Because this script... isn’t something one person can complete alone. It requires the cooperation of several girls.

For heaven’s sake, even in open-minded Japan, what decent girl would agree to this kind of script?

...

"My name is Nakano Ichika."

"My name is Nakano Nino."

"My name is Nakano Miku."

"My name is Nakano Yotsuba."

"My name is Nakano Itsuki."

Today, they accepted an invitation from a certain "great system." In order to achieve their respective goals, they decided to seek out someone with the surname Imazumi and perform the script together.

It’s just that this script... is way too embarrassing...

Lin Yu traveled to the world of Japanese anime and found that he was a neighbor of a dead elementary school student. He also found that Demon Slayer, Bleach, and Naruto had appeared. In such a dangerous world, what should he do? Fortunately, the diary system was awakened at this time. So he made the anime goddesses hate him so much that they went crazy looking for him. "Xiaolan, do you want to know where Kudo Shinichi went?" The song of the little dragon man sounded: "I won't tell you, I won't tell you, I won't tell you, you, you!" "Tsunade, do you want to know how Nawaki died? If you have the guts, find me!" "Haha, if you want to find me, dream on, who doesn't have a few vests?" "Sister Misaka, if you have the guts, hit me, hit me!"

Qin Tian, who was accidentally sent away by a truck driver in his previous life, traveled to the world of Zongman and was bound to the [Fantasy Creation System].

Energy points can be obtained by transforming the origin of the world to create all things.

So Qin Tian set his sights on the original characters.

"I think these original characters are all good leeks because they have the origin of each world."

Using the system to create a dream space, he made various animations, games, and movie plots he had seen in his previous life into dream copies and invited various original characters to participate, so that they could draw some world origins in their dreams to provide energy for themselves.

By the way, he took out some energy and manifested various "treasures" as rewards for participants.

So...

Why did the eldest lady of a certain consortium pose strangely with her valet late at night?

Why did the pink-haired social phobia girl summon the devil in public?

Why did the service department frequently hear the sound of slurping noodles and the door was frozen all year round?

In this way, one original character after another was invited in his sleep and was forced to suffer and be happy in the dream game copy created by Qin Tian...

Takumi Takahashi in the Multiverse

After crossing into an anime mashup world, Takumi Takahashi barely had time to enjoy his youth before being bombarded by evil spirits, cursed entities, ghouls, and monsters. Slacking off was never an option—survival meant working for the System that brought him here.

Miko Yotsuya: "With Takahashi around, I actually feel safe for once."

Yukino Yukinoshita: "Now that I know the truth of this world, I must save more people. You'll help me, won't you?"

Kaguya Shinomiya: "Today, I’ll make Takumi Takahashi confess to me—or else…"

Utaha Kasumigaoka: "Senpai, care to help me... find inspiration?"

A harem of heroines who don’t realize they’re in a death game.

(The combat power of all worlds has been balanced. Apologies for the ooc character design. The last Xu Fu kiss is adorable.)

Su Yin traveled through the Type-Moon world and thought he would become an ordinary person and live his life in fear, but unexpectedly he was bound to a knowledge system.

At the beginning, he gained the ability of [Knowledge Deconstruction] and was pulled into the chat group of all worlds, and from then on began his journey of continuous adventure across the world.

"Knowledge is the cornerstone of modern magic. With enough knowledge, any magic trick, even sorcery, can be deconstructed!"

——Su Yin

Coming to this world and seeing all kinds of familiar anime characters and campus characters from his previous life, Su Zhou thought he had won the resurrection match and was preparing to enjoy his life and go to defeat the familiar beauties such as Yukinoshita Yukino, Mizuhara Chizuru, and Kato Megumi.

But the system came knocking on the door.

[“Ding, host, your Strongest Sword God system has been successfully bound and a quest has been issued: Defeat any monster to receive a Novice Gift Pack.]

After looking at the task and then at the monsters being fought on the opposite side, Su Zhou just wanted to ask if the system was messing with him.

…

Until the mysterious side door was gradually pushed open by Su Zhou, Su Zhou also slowly understood the truth of this world.

Detective Conan? Oregairu? Saekano? Turns out I've been transported to a crossover anime world! The air is thick with hormones. Hasezawa is ready to find some fun in this boring world of romance~

And so, the zombie siege began! Will Megumi, the Saint, remain unfazed amidst it all?

Now, let's have some fun together!

Possessing the powers of Amon from Lord of Mysteries, a mysterious being who adopts Amon's identity, a true god with errors and dual sequences, wearing a monocle, I am a con artist who travels through countless worlds. In Soubu High School, I made the entire school do calisthenics with me; in Fuyuki City, the Holy Grail War turned into a prank war; in Marineford, I turned the Marineford War into a massive rave.

Don't ask me why, the answer is simply—it's for fun.

This is a story about chaos, laughter, and a touch of tenderness. Of course, it's mostly chaos.

Friendly reminder: Don't be afraid, please hug your blanket tightly before reading, after all, I won't suddenly appear beside you.
