[Under One Person + Gender Change + Fireworks (The Ultimate Venomous Fun Person) + Extreme Joy + No CP]

Just because of seven consecutive fireworks, Luo Yun was sent directly to the world of "under one man" by the God of Fun Aha. He changed from a 185cm male college student with abdominal muscles to a 145cm little loli who looked like Fireworks. He was also bound to the Chosen Fun Person System. As long as he played the role of Fireworks and gained pleasure, he could unlock new abilities and continuously improve his strength.

Thus, a quirky girl, an outstanding drama master, and a dangerous masked fool appeared in the alien world. She was not interested in wealth, status, and power. The only thing that made her take action was [fun].

She fooled Zhang Chulan, played tricks on everyone in Quan Xing, and even made the Ten Lords dizzy. She gained endless joy from the grand dramas she directed, one after another.

Zhang Chulan: "Hua Huo, you are not a human! Give me back Pella!"

Xia He: "Damn it! Why is Hua Huo prettier than me?"

Wang Ye: "This girl is really good at playing games. She even deceived herself!"

…

Playing Hanabi? No! From now on, I am Hanabi!

What is joy? I am joy!

Ahahahahahahahaha!

Ahahahahahahahahahahahahaha!

After traveling to the world of Honkai Impact 3rd, Lin Xi is bound to a "Seele Simulator." By successfully conquering or rewriting the fate of plot characters in various simulations using Seele's persona, the host will receive character-specific talent rewards. However, if the simulation's evaluation is too low, the host will not only be locked out of the relevant scenario, but will also be forcibly bound to some "strange" talents after the simulation ends. As the simulation progresses, one beautiful girl after another falls for Lin Xi's Seele persona. So... Alicia: Seele, when will our wedding be scheduled? Mebius: Let's do something fun, sweet little Seele. Big/Small/Honkai Impact 3rd: Seele! Bronya finally found you! Let's get married! Kiana: Seele is truly gentle and adorable! Lin Xi, while posing as Seele in the simulation to reap the benefits, is completely unaware that she has completely taken on Seele's form. Lin Xi: You're looking for Seele, what does this have to do with me, Lin Xi? Until the object in the simulation, and even the real person in the quantum sea, came to force a marriage...Lin Xi: I'm so excited!

(Anime crossover, light novel)

Thanks for the invitation. I'm in One Piece, and I start out as Black Hairless.

Wandering the seas, free and unrestrained, but—

Why is this eagle-eyed rascal chasing me around all day? What? My son offended you? Then go find Xiao Mo! Why are you bothering me?!

Garp, why are you chasing me every day? Huh? Where's Great Britain? Can't you find it yourselves? Inviting me to join the navy? Me, the King of Great Britain, are you kidding me? No way!

Redheads? Giving you face? Not getting involved in the summit? Giving a cripple the run for his money! Asking for a beating!

Huh? I'm not that Black Hairless guy! What does your looking for Black Hairless guy have to do with my Gundam? You've got the wrong person!

【Comics】＋【Chat Group】＋【Daily Life】＋【Transformation】

After crossing,

[Ding, the Wanjie chat group invites you to join, do you agree? ]

Huanyue not only turned into the appearance of Xiadie, but also possessed some of Xiadie's abilities. As long as she helps others, she can earn points to unlock more abilities.

After Huanyue entered the chat group, the world began to change, and her world gradually merged with other anime worlds.

There are various characters she knows in the group chat, and she can also gain other people's abilities by helping others.

Xiadie: "In the face of death, even disputes will give rise to hesitation."

Shadow King: "I know you're helping me farm monsters in the dungeon, but why did they all die when they got close to you? I still want to farm."

Tanjiro: "Although the smell of death on Xiachou is very strong, it is very gentle!"

Rab: "Thank you for your help, Miss Xiadie. Would you like to have a drink with me?"

Da Congming: "Miss Xiadie's hands are very beautiful? Then be careful, there seems to be a man here who likes to collect women's hands..."

I'm not an evil slime: "Miss Xiadie is actually the messenger of death. It feels like she is on par with our Demon King."

After completing the mission objectives by integrating all the worlds, Huanyue suddenly found that her originally empty social network had become complicated...

(Fusion World: I Leveled Up Alone, Demon Slayer, Akame ga Slash, That Time I Got Reincarnated as a Slime, Wanting to Become a Shadow Master, JOJO: Diamond is Unbreakable... To be confirmed)

[Zero Zone + Daily Life + Funny + Invincible + Fun Person + Playing as Fireworks!] After traveling to the Zero Zone world, Sulin obtained a role-playing system and transformed into the most beautiful "Fireworks" lady in the universe. As long as she seeks fun, she can improve her role-playing level and gain the ability of "Fireworks"! Shark girl Ailian: "Want to touch my tail? No... Sulin, if you really want to touch it, can you not do it in front of so many people next time..." Phaethon Tetsu and Ling: "If she is Phaethon, then who are we?" Nicole: "Who stole my identity and sold the Rabbit House!!!" Nekomata: "Sulin, what are you doing here again, meow, that's my mackerel, give it back to me, meow!" Keleda: "What, you want to join Baiji Heavy Industries, on the premise that Grace can do anything? Of course no problem!" Hoshimi Miyabi: "You are very strong, I will definitely work hard to catch up with you, even if it means sacrificing myself, wait... not this kind of sacrifice!"

"Because glory lies far away!"

On the Magic Eye Collection Train, the Rain Witch smiled with satisfaction as she watched El-Melloi II display the might of the king's army in front of Hephaestion.

"Broken down~"

In the world of Artificial Girl + Rozen Maiden, the fairy tale witch hugged the mercury lamp and hummed briskly with light steps.

"This is a friendly vampire."

In the world of Bloodthirsty Assault, looking at Nangong Nayue with a wary face, Elquet smiled and waved.

"Seven dragons, turn into my fingers!"

In the world of Problem Child, Draco (Beast Nero) rushed towards the high sun with a grin.

...

Since you are here, come in and take a look

I've traveled to the world of Uma Musume and gained access to a 2D armor system. Yay!! Let's do something, let's do something! Do you like this Uma Musume armor with 2D templates? ... Amusement Park Knight (Platinum): "I don't feel like working hard today. Want to go out for a stroll in the city with me?" World Devourer (Mobius): "Little white mouse, where do you want to go? Let's play some games~" Qiqi's Favorite (Ganyu): "Want to work overtime with me, Miss Luna?" So! Say! Isn't this a good idea? Right?

The boy died, the girl lived.

When I opened my eyes again, I was not in a white hospital room, but in a cold, dark space.

There is no sun here, no earth, only deathly silence.

He also noticed something was wrong with her; she seemed to have been reborn, and not only did she resemble Hoshimiya Rokuro from the anime Date A Live, which he had watched before, but she also possessed magical spirit powers.

At the same time, she discovered that he was dead, his body beside her. Although she could not sense any signs of life, she felt as if she were still connected to him...

Suddenly, hope filled the girl's heart, and she decided to seek the realm between life and death, embarking on an unknown and long journey.

Her first stop was actually—

One Piece, Akame ga Kill!, Naruto, Re:Zero -Starting Life in Another World-, Overlord, Godslayer, Jackie Chan Adventures (in progress)

P.S.: The good news is that the author doesn't know how to write romance; the bad news is that the author only learned how to write exciting battle scenes.

I got seven gold cards in ten gacha pulls, then was struck by lightning and transported to the continent of Teyvat. When I woke up, I found myself transformed into Kiana! Although there's a system where you can get Primogems by completing achievements, there's a more important problem now...

Ying: "Is this photo of you?" (She takes out a photo of Tianli)

Kiana: "Is... no... this isn't me!"

Ying: "I think this is you!" (She pulls out a weapon to persuade people with reason)

Kiana: "Wait a minute! This really isn't me!"

Bai Chen was still bragging and chatting with his best friends on the road, but he lost consciousness the next moment. "I seem to be dead? How did I die?! This is too weird!" Bai Chen was still confused by his sudden death when he found himself in a dilapidated city. This is... "Kiana! You're in trouble again!" "No, Mei! I wasn't in the dormitory yesterday!" "Captain Qin, someone reported that Klee's explosion yesterday afternoon affected some crops." "But Klee was in the confinement room all day yesterday?" "I seemed to see two Bailu ladies rescuing injured people this morning." "Did Lady Dragon learn the art of clones to treat the injured more quickly?"
