A mysterious game called "Ghost Paradise" has changed the world. Following this, an invitation arrives, and Gray joins a chat group called "Mutual Help." The group contains requests for assistance from various worlds; completing them earns a reward. The reward isn't important; the main thing is enjoying helping fellow group members. Yukino Yukinoshita: If I hadn't seen it with my own eyes, I wouldn't believe demons could be blackmailed. Gray acted steadily, unlike a first-time offender. Toyokawa Shoko: In less than ten minutes, she completed an arson attack. Her skill was so practiced, it didn't seem like a first time. Does she really have no prior record? Alicia: The Herrscher occupied an abandoned city as a base, and Gray rushed in and de-urbanized it. Afterwards, the Herrscher came and questioned us about who the Honkai Apostles were. I have mixed feelings. Houraisan Kaguya: She's clearly a beautiful woman with both strength and looks, but she acts like a ruthless bandit. Gray: Who acts like a ruthless bandit? I'm a law-abiding citizen… [Ding! The group name has been changed to "Truly a Mutual Help Group, No Ruthless Bandits in the Group."] Gray: ? P.S.: I already have four completed books, three of which are over a million words long. Updates are guaranteed, so please feel free to add them to your collection and read them. P.S.: This new book is now available, so please, both new and old readers, give me your votes! Thank you so much!

I got isekai’d? Seriously, who even does the whole "transmigration" trope these days?

And a system too? Just a reskinned "Heroic Spirit System," huh?

But what kind of skills is this thing giving me?! What the hell does "Bishōnen Seducer" even mean?!

Tokisaki Kurumi: Ara ara~ Nanjō-kun, you’re just adorable, aren’t you?

Nanjō Saku: Who said this skill was useless? This skill is freaking amazing.

Qin Qi transmigrated to the Fairy Tail world and possessed the magic of the Royal Treasury. He thought he would grow into a king in an ordinary way. But unexpectedly, he received a mission request from another world, but the Black Dragon's destruction of the world was getting closer and closer! [Lucy: "Royal Treasury, you didn't even say the Arms King's Treasury! What the hell is this 'cannon blasting'?!"] [Erza: "He said he wanted a one-on-one fight, and then he just ran over there and annihilated me from 8,000 meters away! How am I supposed to fight him?! Are you taking advantage of my short reach?!"] [Nami: "I just told him I wanted to destroy Arlong, and then he just blasted the place flat!"] [Joseph: "Your next line is, 'Thompson Ripple Dash'!"] [Frilian: "It's a magic that rapidly launches small steel balls. This thing is much more useful than a staff."] [Black Dragon Acrogia: "Huh? Me fight this thing? Can I win? I'll die!"] [Makarov: I feel a chill down my spine!] [Qin Qi: "When I pulled out my magical nuclear bomb, what Black Dragon? It's just a big lizard!"]

Louise: "Only I would tolerate your hentai lolicon behavior, you demon king, so you must always love me~"

Stella: "I am the princess of the Kingdom of Familion. It is my good fortune to meet you on the path of seeking higher goals and becoming stronger to protect my country. And it is even more fortunate that you are also a dragon."

Aiko: "The heavy responsibility of continuing the royal bloodline of the Holy Dragon of Avalon now falls on our shoulders. You better take responsibility!"

Emilia: "I am your queen, you are my husband, my dragon god."

Alicia: "Hi~ It's great to see you again. This time we'll definitely be happy together, right?"

Kiana: "I will never let go of your hand, because you are my other half!"

......

......

Kurima: "I only wanted to take on a talented disciple so I could show off to my acquaintances, but why did she end up becoming my husband?"

When Yi Chen stepped into the world of "Godslayer", a new ironclad rule was added to the world.

"In the magic world, I'm the one in charge. Who agrees? Who disagrees?"

The Silver Hand of the Sword King is nothing more than a slightly thicker Qilin arm, and the wolf kept by the Norse Marquis is actually no different from a husky found on the street.

A disobedient god? He'll smash you with an elbow!

The Last King? He'll elbow the other gods first, then you.

But before that, the white-haired loli named Athena came over and bowed her head, saying, "I have some delicious food here."

Yi Chen: "Sigh, whose card should I choose today?"

This is a fantasy novel featuring an invincible protagonist across various anime worlds. Readers are welcome to discuss and offer feedback. As a new author, my early work might not be great, but I will continue to improve! I hope everyone will have the patience to read on.

Transmigrating to various anime worlds, Lin Yi is bound to a god-level sign-in system and starts his journey by parachuting into Demon Slayer!

Sign in at the Kamado house to unlock the Demon Blade Thousand Blades, unleashing a multitude of blades to slay all evil spirits; sign in at the Wisteria Forest to obtain the perfect inheritance of the Breath of the Sun, where the blazing sun burns away the darkness of night.

Starting from the world of Demon Slayer... In each world, he keeps checking in and getting stronger! Eventually, he becomes an unparalleled powerhouse spanning multiple anime series!

Fatti, transmigrated to the world of DanMachi, starts with a fully-equipped arsenal of three magic spells and seven skills. Unfortunately, his potential is extremely limited, preventing him from seeing further. It's only after accidentally discovering a hidden treasure chest function that his life takes a dramatic turn. He opens invitations to recruit familiars from other worlds, acquiring various magic books and transforming himself from a mage into a noble sorcerer. With the goddess Demeter as his backer, he secretly accumulates strength, manages his familiar, and quietly develops his power. From then on, he cautiously and steadily begins his fantastical life in this other world.

Yao Jia probably never expected that hitting the jackpot would actually damage his soul.

Countless fragments of souls, carrying Yao Jia's essence, crossed dimensions and were reborn as familiar or unfamiliar two-dimensional beings.

After retrieving the reincarnated soul fragments, Yao Jia, as the main body, could directly resonate and gain power, but unexpectedly, all the clones were of the opposite sex...

Huo Yuxi: "Can a mere God Realm withstand a punch from me, a being of stellar level?"

Liu Ou, "Comprehend the laws of space? Would you like to see my spatial authority?"

Kiana: "All tragedies crumble before 'me'!"

Yao Jia some time later—

"Was I really this narcissistic?"

My wife is so beautiful! (×)

I'm so beautiful! (√)

He is the king who slays gods. He is the overlord who rules over all people. His words are the law of this world; you should fear his name, submit to him, pray to him, and praise him aloud. All people must remember: you should kneel before the demon king. In the endless world, Yuzuru Nozomi will eventually become the king of all heavens.
