As the Queen of Succubi, I appeal to the entire demon world for help: To corrupt a 17-year-old boy, I have transformed into the Otherworld Welfare System, attached myself to him, and begun my seduction! Dear host, you possess the ability to transmit your innermost desires to beautiful girls. Please have Yotsuya Miko... "Ripple!" "These are ripples that convey my will and enlightenment! The hymn of humanity is the hymn of courage!" Beep! You have awakened your seductive nature, making Goto Ichiri yours... "Do you believe in gravity?" "Human encounters are meaningful. If you want peace of mind, follow me." Beep, you can now stop time. The limit is five seconds. If you want more time, I command you to... Shinomiya Kaguya... "Enough! Five seconds is enough to dominate the entire world!" "And then I'll kill you, you bastard, in less than a second!"? Gazing at the invincible figure approaching, his fist piercing the sky, and behind him, the determined faces of the heroines who have overcome their fate, completed the trials, and grown. There were even many Taiman Ninjas, Magical Girls and the beautiful superpowered girl Succubus Queen whose lower abdomen trembled with phantom pain. Can reconciliation be achieved?

After being blown away by a dump truck, Qian Yuan arrives at FGO's seventh singularity, the Absolute Demonic Front. What should he do if the world is about to end? Fortunately, his soul was replicated and scattered across the universe. Mei from Honkai Impact 3rd, Lei Yingying from Genshin Impact, Rin Tohsaka from Warcraft V, Shoko Toyokawa from MYGO, Ai Haibara from Detective Conan, W from Arknights, Illya from Makai, Athena from Godslayer... Qian Yuan can share power with his alternate selves and travel through the worlds, but why are all my other selves girls? My wife is actually me.

After waking up, I traveled to another world. The bound system was still a system without a name, could not speak, and never issued tasks. It only had an "energy bar" that increased a little every once in a while.

Fortunately, after traveling through time, he inexplicably gained the ability of absolute memory, which allowed him to not worry about his life.

Just after he embarked on the path of plagiarism, he moved to the home of his aunt, who was also from a single-parent family. His aunt had an only daughter named Kiritani Suguha...

Just after he accepted the semi-sci-fi worldview, he had just attended high school for half a year when the school suddenly announced its closure and was to merge with the Ju Wang College that had appeared out of nowhere in the same town...

The white-haired, silent lolita in front of me is fine, and the person next to me is Yuuki Asuna, which is also understandable. But what about Yuuki Mikan's sister? It seems that her sister also has a good friend named Yoshimura?

The homeroom teacher's surname is Gengdao, and he has a daughter who just got into the University of Tokyo?

Sun Baihe time and again traveled through time, searching for his way home. He had once teamed up with Asuna in Sword Art Online, their combined swordsmanship reaching the top of Aincrad; he had also used his 3D Maneuver Gear to slice through the nape of a giant's neck in the world of Attack on Titan; he had studied magic at the Clock Tower, only to be unexpectedly swept into a time warp, returning thousands of years to teach Artoria how to govern; he had shared drinks with Whitebeard, and later single-handedly conquered Mary Geoise, the holy land of the Celestial Dragons, ending their rule; he had debated swordsmanship with Retsu Unohana, experienced Sosuke Aizen's Kyoka Suigetsu, and dominated the world of Bleach, seemingly undefeated; he had even been slammed in the face by the White Tyrant, and became friends with her… After countless hardships, he returned to the main world, exhausted both physically and mentally, becoming a lazy bum who only wanted to rest for a few hundred years. But unexpectedly, the sixth wave of spiritual energy revival opened countless dimensional portals. Seeing familiar faces on the television screen, Sun Baihe shuddered. "Damn it, the debt collectors are here!"

"Ms. Mengyu, thank you so much for accepting our interview." The host greeted Luo Yu warmly. "It's nothing, you can start asking whatever you want to ask." Luo Yu gestured to the host that they could begin. Host: "Let's begin then. Ms. Mengyu, this fan says your game [Honkai Impact 3] is falsely advertised; it's not a healthy, positive, and uplifting mecha battle game featuring beautiful girls at all." "Fake News!" Luo Yu stood up excitedly. Host: "Ms. Mengyu, please calm down and sit down first." "No one knows Honkai Impact 3 better than me." Luo Yu said, sitting down. Host: "But they say you're engaging in false advertising." Luo Yu: "My game doesn't have any cute girl stickers?" "..." "The game doesn't have any mecha battles?" "..." "Then why do you say my game is false advertising!" "Okay, our program is now over."

He traveled through time and space, becoming a captain drifting through the vast ocean of Honkai Impact 3rd, achieving a perfect ending and living a happy life. However, the belated system brought him back to a time before the main storyline even began, when the three little ones were still fighting for survival in Changkong City.

"It's a second time travel, so why did you lose all my clothes when you teleported?"

"What do you mean you only got the right to use the Divine Key? This Divine Key isn't on my ship. I stole it from its original owner and have to return it after use."

"What the hell is Theresa Killer? How could I possibly have such a talent?"

The introduction is weak, please read the main text.

This noodle is so delicious! Nangong Shuoyue exclaimed, and then a ding echoed in the boy's mind. The belated cheat code had arrived. A chat group for all realms? The group owner is the collective will of the heavens and all realms? You can become stronger by spending money? Interesting... The boss pretending to be a newbie smiled happily. Gensokyo, One Punch Man, Oregairu, Overlord, One Piece, Naruto, Bleach, Akame no Kill, God Slayer, Tokyo Ghoul, Boring Girlfriend, Puella Magi Madoka Magica, K, No Game No Life...

Crossing through Fuyuki, looking at the blood-red pattern on the back of his hand, Novell decides to speedrun the Holy Grail War alone in order to avoid becoming a victim of everyday gas explosions.

—————

"Ahem, Tohsaka-san, what do you mean I'm some old monster who's lived for who knows how many years? I just recently learned a few little tricks so I can survive in the Holy Grail War."

Novell looked at Rin Tohsaka across from him, whose eyes were filled with deep suspicion.

"Huh? You're asking me why I'm so skilled at rune magic?"

"Of course, it's all about practice, cough, practice makes perfect."

Cheng Mo's life fell into despair.

My younger sister is seriously ill and her studies are on the verge of collapse...

Until he picked up a mysterious compass, his life took an outrageous turn——

Save Nezuko, accept Tanjiro as his apprentice, and get involved in the dispute between the Demon Slayer Corps and Muzan...

"Wait, didn't you agree to just be a profiteer?"

"My Lord, let's discuss business. I'll sell you penicillin, and you'll teach me breathing techniques, how about that?"

"Ms. Tamayo, I have a report on modern genetics. Would you mind using some of my blood to study it?"

"Muzan? Oh, don't run away with that moving gift bag of time and space coins!"

Cheng Mo just wants to resell resources and make enough money to save his sister.

When he looked back, he discovered that he had already held the authority of countless worlds and became the largest behind-the-scenes supplier in the heavens!

Tanjiro: "Teacher, what is the 'currency' of this world?"

Cheng Mo: "It depends. Maybe it's a devil fruit, maybe it's chakra, maybe... the future of a world."

(This book is also known as: "I Resell Supplies in the Heavens" and "After Accepting Tanjiro, I Became the MVP of the Demon Slayer Corps")

[Mainly focused on abundance, multiple Fate Orders, easygoing daily chat groups, leaning towards invincibility, multiple female protagonists, including Bai Heng] Nan Li travels through Collapsed Iron and becomes Luofu Jianmu. Just as she's about to stretch, she's warned by Lan Ge's arrow. After centuries of silence, she joins the chat group. Huh? Did Goslayer's Sword Saint end up in the world of reincarnated slimes? What about the monsters Golzan and Melba ending up in the world of the Silent Witch? Upon learning the truth about her parents' deaths, Xin Nan transforms into a monster-killing machine. What will happen if Frieza, the Emperor of the Universe, arrives on Earth to face the One-Punch Bald Demon King? In the world of Ultraman Tiga, Nexus loses her accuracy and fights alongside Daigo in the TPC. Nan Li, dressed as Luofu Jianmu, said, "The Medicine Master never refuses prayers, and he grants blessings indiscriminately. This is a disease that must be cured!" "Nanook believes that civilization is a cancer in the universe, so he stirs up strife and destroys civilization. He deserves to be the first messenger under the Throne of Plenty!" "The Tree of Imaginary Numbers? I might even be able to compete with him."
