At the sacred wedding, the bride and groom accepted the blessings of their family and friends. The newlyweds looked at each other, smiled happily, exchanged a vow kiss, and began their new life amid applause. It should have been like this, but at Lei Luo's wedding... "You, Artoria, can touch me, but I, Artoria, can't?! We're all Artoria, why do you have all the privileges?" "...That's it! Holy Lance, weigh anchor!" "Who's afraid of who! Unnamed Victory Sword!!" "...Excalibur!" "Um, um! I'm sorry! Calibum!" "Wow, even if it was another me, anyone who steals the king's possession deserves death! Excalbur Morgan!" Lei Luo, who should have been the protagonist, could only watch helplessly as his bride and a group of "herself" fought each other.

After traveling through the world of Demon High School and wandering around in it for a thousand years, when Chen Eliog became the fifth demon king of the underworld, he received an invitation from a dimensional chat girl.

Out of boredom, Chen Eliog chose [Accept].

Cang Yue: Welcome newcomer! I am the strongest fighter among all the girls, let me know!

Esdeath: The person above is talking nonsense! I am the strongest fighter among all the girls, let me know!

Yukinoshita Yukino: Hello newcomer! As an ordinary person, I am trembling between two big guys!

Shinomiya Kaguya: +1!

"…………"

Chen Eliog: "Thank you for the invitation! I am in hell and have just become a demon king: I have official business to attend to, so I will hide for the time being."

After traveling to the world of anime, I was expecting to live a romantic life with my fiancée, but unexpectedly, all sorts of strange creatures appeared. Dragon maids, magicians, and ghosts began to appear from time to time. "Come if you want, just don't interfere with my life."

Yours Truly shall have all of you bow down to me!

Arriving in this brand-new world, Lin Fan found himself in possession of a system which allows him to level up indefinitely unbounded by the limitations of this world. Upon learning a powerful technique of Monkey Steals Peaches, Lin Fan realises that he’s poised to literally become the strongest person in this entire world. But of course, how boring would that be unless the whole world gets to know about his great name?

Shameless. Righteous. Smart. Lin Fan will let no one (or balls) stand in his way to glory!

When the Blacklight Virus came to the One Punch World and had a chat group.

Group leader Zhao Zheng: "Brother Corpse Little King Kong is nothing. I rely on the Bald Big Devil to become a god-level disaster! Tornado on the left! Blizzard on the right!"

Qilin from Super Seminary: "The Taotie and demons who slaughtered the people on Earth were being called names by the group leader. I heard they even tasted like chicken?"

Uzumaki Naruto of the Ninja World: "What are aliens? The tailed beasts and Otsutsuki here have been eaten by the group leader."

Adventures of Xiaoyu: "Eight demons, twelve spells, and nine ghost masks are all nutrients for the group leader!"

Demon Slayer Nezuko: "They say that demons eat people and make people afraid, but the group leader makes demons afraid and eats them!"

Dagu: "The monsters here have almost been eaten."

Ye Hei: "What's your side? In my restricted area, everyone who tried to start a dark turmoil was eaten up by the group leader, and it became the dark turmoil of the restricted area!"

Naruto, Super God, Jackie Chan Adventures, Armor, One Piece, Demon Slayer, Dragon Maid, Valkyrie, Dragon Ball, Marvel, DC, Ultraman, Covering the Sky, Perfect...

…

Many years later, thanks to the chat group of all heavens and worlds, Zhao Zheng became the most powerful and supreme being in the heavens amid the cheers of his group members who were the most benevolent, kind, supreme and powerful!

"Heh! You don't even have the strength to hit me, yet you have the nerve to say you want to kill me?"

Recently, Gu Fan, the president of Nitiantian Games, once again fell into the spotlight because of a small bug in the new game.

As a top designer in the industry, all games designed by Gu Fan have very distinctive characteristics:

At first, players felt that these games were junk games with boring gameplay and purely disgusting players.

But after players discovered a major BUG, the gameplay of these games has undergone earth-shaking changes, making people sleepless and unable to stop!

As a result, players once again started a big discussion about "Is this a BUG or a game mechanism?"

In this regard, Gu Fan seriously clarified in the interview:

"Hello everyone, I am Gu Fan, a game designer. You can also call me by my English name: fan·gu (anti-bone).

"I solemnly declare once again that these so-called 'core gameplay' are not our company's original design, they are all BUG! It's just because players like it, so we haven't fixed it!"

Transmigrating into the world of the "Hakoniwa" (Little Garden) in the world of crossover anime, Izayoi Sakamaki, while waiting for her invitation to the Little Garden, was invited to the Multiverse Chat Group and became its strongest member. Esdeath: "Izayoi, I will definitely not let you leave me too far behind!" Rikka Takanashi: "My contractor, following the ancient oath..." Nagatsuki: "You are hundreds of times stronger than the True Ancestor!!!" Touhou Project: "Um... Boss, do you have any extra Third Star Particles? Can I borrow some?" Gilgamesh: "I, the King, declare you the strongest!" Brunhilde: "Lord Izayoi, please save humanity!" Izayoi Sakamaki: "Thanks for the invitation, just arrived in the Little Garden, challenging the Celestial Theory." With her absolute power, Izayoi Sakamaki also became the chat group's sole administrator...

Xia Chen unexpectedly transmigrates to the world of One Piece, activating the story island check-in system right from the start.

"What? You get stronger just by clearing story islands? Doesn't that mean you're about to take off?"

Upon visiting the first island, Windmill Village, I obtained the Zoan-type Mythical Beast Fruit, the Great Sage Equal to Heaven form!

Is Nika the Sun God really that powerful?

Do you know that even if you become a god, you're just one of the 100,000 heavenly soldiers and generals who can stop me?

He then happens to meet Luffy, who is just about to set sail, and at Luffy's invitation, becomes the vice-captain of the Straw Hat crew.

Join the main characters as they explore story islands and grow stronger!
