Official Introduction: Now approaching you is: Muzan's nightmare, the destroyer of the Twelve Demon Moons, the head of the Infinity Castle demolition office, the most righteous person in the Demon Slayer Corps, Sabito's savior, the eternal absentee of Kanae Kocho's tea party, Giyu's good senior brother, the founder of Fist Breathing, and a grandmaster.

Willow branches provide shade, that's it!

Kanae Kocho: "I invited him to a tea party ninety-seven times, and he refused ninety-seven times. He's so gentle."

Shinobu Kocho: "Why should I be trained by iron fists? It's infuriating, sister!"

Akaza: "A powerful person, the best in physical combat."

Muzan Kibutsuji: "A monster who destroyed all my Demon Moons with his bare hands and blasted the Infinity Castle to pieces, you call him human?!"

Unofficial synopsis: Yagyu In transmigrates to the world of Demon Slayer, but the system believes he is in the world of One Piece and identifies him as a Marine.

You can earn Navy Points and rewards by doing things that are in line with the Navy's rules.

Yagyu In: No, buddy, is this right? Where did this pirate from the Demon Slayer world come from that I need to catch?!

Pirates are attacking! Strike immediately to capture or kill them!

Looking at the man-eating ghost before him, Liu Shengyin realized that the system had gone mad.

From then on, the Demon Slayer Corps had one more instructor who liked to smash people's heads with his iron fist of love.

This book is also known as "Left Fist's Overpowering Entanglement Deals High Damage, Right Fist's Overpowering Entanglement Deals High Damage," "Three Punches Shatter Evil Spirits, Sir, I'm Just an Ordinary Person," "Overpowering Aura is Also Qi, and Qi is Breathing Technique!" and "Muzan, Are You Hiding Well? The Marine Admiral is Coming to Get You~"

Note: This book is a crossover anime/manga series, and will later explore other worlds.

Lin Ming has been in this world for sixteen years, always believing it to be an ordinary one. He copies novels, saves up small amounts of money, and dreams of a simple and happy life with female seniors on his left and female juniors on his right.

It wasn't until he stepped into Kuoh Academy and saw Toujou Koneko's cat ears, Himejima Akeno's lightning, and Rias's destructive magic... that he realized with despair that this was "High School DxD," a place where people could die! The aftershocks of the mystical powerhouses fighting could obliterate him.

In a moment of crisis, the Infinite Dimensional System awakens: Afraid to become stronger? Newbie quests force you to make extra-long confessions to three popular heroines! Too afraid to take risks? Then traverse countless worlds for forced training!

I traveled to the Naruto world and became one of the two survivors of the Uchiha clan massacre.

Lin Shi thought he could live a good life through hard work, but unfortunately, the Konoha higher-ups set a trap for him, causing him to fail the Chunin exam.

Fortunately, the Awakening All-Heavens Chat Group System allows you to become stronger simply by participating in the storyline.

What else is there to say, bro? I'll just be a model worker.

Thus, a troublemaker could be seen throughout all the heavens and myriad realms.

Gojo Satoru: I'm so sorry I couldn't make Lord Lin Shi enjoy himself.

Misaka Mikoto: You idiot, Lin Shi, come to my room tonight. Don't get the wrong idea, we're just going to talk about the sisters.

Esdeath: You are very strong. Let's have a fight. The loser will become the other's slave.

Shinobu Kocho: Mr. Lin Shi really is a womanizer, having so many older and younger sisters.

Whitebeard: Lin Shi, you're really awesome, be my son!

Allen: Tataka! Tataka!

[Currently, the tentatively confirmed worlds include: Naruto, Akame ga Kill!, One Piece, Demon Slayer, Attack on Titan, Jujutsu Kaisen, A Certain Scientific Railgun, and The Burial of Freeland... If you want to see more worlds, please leave a message in the comments section.]

Kitagawa Yuu, who traveled to the world of anime, originally hoped to achieve financial freedom quickly by relying on the songs he remembered from his past life, and to find a beautiful girl to always be by his side. However, as his "talent" continued to unfold, he suddenly realized that there seemed to be a bit too many beautiful girls who liked him. So... "I'm so sorry! I really didn't intend to have a harem!"

I woke up to find myself transmigrated into the body of a top-tier rich kid on an alien planet. I thought I could finally relax and enjoy a life of luxury, but a cataclysmic change suddenly struck – humanity was forcibly relocated, scattered across the vast universe. The cruel laws of the stars revealed themselves: each person randomly draws a ship and companion, ranging from an F-class mining vessel to an SSS-class interstellar mothership, determining the life or death of their civilization. Just as I was about to draw, the [Lucky System] suddenly bound itself to me, along with a [Today's Limited-Time Lucky Card]! "Ding – Congratulations on obtaining the unique SSS-class ship, the interstellar mothership!" (Its size is comparable to half the Earth!) "Ding – Congratulations on obtaining the unique companion, the interstellar mother!" (Capable of hatching billions of Zerg soldiers!) While others boasted about their B-class cruisers and complained about their F-class fishing boats in the interstellar channel, I looked at the mothership that blotted out the sky behind me and the restless mothers beside me, and silently chose to hide my information. "I'll develop discreetly for now. My journey is this very starry sea."

Transmigrating to the Douluo Continent and becoming Huo Yuhao, he unexpectedly arrived in the Douluo Era 1 and even activated a diary system, earning rewards simply by writing in his diary each day. Originally, he planned to develop his strength discreetly, focusing solely on becoming stronger and building his career. However, as he wrote, Huo Yuhao noticed that all the female characters were acting strangely. Bibi Dong and Qian Renxue were openly and secretly vying for his attention. The Ice and Snow Emperors had transformed into human form, and the dormant Gu Yuena had prematurely awakened, bringing her auspicious beast to his door. Even the three beauties of Shrek Academy had abandoned Shrek Academy, revolving solely around him. Was it them who were acting strangely, or was it him? Xiao Wu: "Yuhao, I'm really not your mother-in-law, please don't call me that anymore!" Qian

Yu Cheng transmigrated into the body of the young patriarch of the Whirlpool Clan. Faced with the impending extermination of his clan, he dared not stop for a moment!

Fortunately, his three adopted sons were transported to the worlds of One Piece, Demon Slayer, and Martial Soul, respectively.

And so—

"Old Cheng! Is the Dark-Dark Fruit any good? Hehe... I want to use the Impure World Reincarnation~"

"Come here! Old Cheng, I'm now an Imperial Beast. Which soul beast do you want as your summoning beast? I'll teleport you there!"

"Uchiha Madara wants to fight you? And the Otsutsuki want to join the fray?! Fine, let's fight!! Behold my Sun Breathing!!!"

——————

Several years later.

Uzumaki Yu Cheng transformed into the Demon King, wielding the Supreme Great Sword, stepping on the Black Dragon Emperor, his Rinnegan lowered, looking down at the dying Allied Shinobi Forces.

"From this day forward, the ninja world will be unified. And I... will stand high in the heavens, becoming an immortal god!"

He transmigrated to Konoha Village, becoming a cannon fodder genin. The Second Shinobi World War raged on, and Natsume's ninjutsu consisted only of the D-rank Three Body Technique and the C-rank Earth Release: Wall. His superiors were utterly inhumane, always using him as cannon fodder, forcing him to narrowly escape death on almost every mission. Natsume felt he could die at any moment. Fortunately, the "Good Boss System" activated. By sacrificing his direct superior or seizing their position, he could gain a chance to win rewards. Sacrificing a Chunin captain granted him the Kagura Mind's Eye. Sacrificing a Special Jonin captain granted him a Jonin-level chakra. ...When the death rate of Natsume's direct superiors became extremely high, he finally faced questioning from Konoha's higher-ups, "Natsume, we need you to explain why your superiors' casualty rate is so high?" "Because they deeply understood the Third Hokage's..."
