As the colossal ship named Black Whale crossed the endless seas, what awaited them was the gatekeeper and the dark continent behind him... What? You're telling me the gatekeeper is Gol D. Roger? The dark continent is full of purple fruits that can awaken Nen abilities if eaten? What...? The Hell Rattlesnake is Kaido? The gas-mist-like life form A is Crocodile? The nurturing beast Papp is Big Mom? Iron Body is actually "Firm"? Finger Pistol is actually "Shoot"? Paper Drawing is actually "Flow"? Observation Haki is actually "Circle"?! Master, I understand! After the Black Whale survived the Great Battle, some died, some escaped, and Kuroro, who rewrote the ending and ultimately won, led the new Phantom Troupe, riding the Black Whale, and set sail! The New World? Isn't this the New World? What kind of extremely evil people are these? Aren't the spiders evil enough?! ...Know...

Father, a ninja's capacity truly has its limits. In my short ninja career, I've observed that the harder a ninja trains and the more desperately they fight, the more likely they are to die a pitiful, short-lived death. You must become someone who transcends the ninja realm! What? Son, what are you saying? I… I'm not going to be a ninja anymore, Father!

I'm just a person who wants to live a peaceful life. Although I've taught the girls a few new tricks and knowledge, I absolutely haven't instigated them to overthrow the world. Those are all their own ideas. I'm really not the mastermind! ...First up is *A Certain Scientific Railgun*, others to be determined.

My name is Lan Yuxing, a high school student. After dying, I was transported to another world and possessed the body of a slime—Rimuru, also known as the "Cute King," because he's so cute. One day, I discovered that the world I'd been transported to was worse than I'd imagined, because the whole world was so chaotic! The Western Hemisphere has vampires, werewolves, and archangels, while the Eastern Hemisphere has Iron Man and the Hulk. There's also a guy named Luffy in the ocean, and in a place called the Hidden Leaf Village, there are two guys named Naruto and Sasuke who are actually arguing about who gets to fight...

Gathering is a blazing fire, scattering is a calamity for all. Mu Yu, traversing countless worlds, initially intended to quietly develop his power and silently ascend to godhood, but he was frequently targeted by villains. To this, Mu Yu shrugged: "Simple, I'll just become a Venerable..." Naruto: Kaguya Otsutsuki, drooling over Mu Yu's immense chakra, was instantly devoured by Mu Yu! Bleach: Aizen's Dao Heart shattered, and the Hogyoku transformed into a stream of light, flying towards Mu Yu, only to be slapped away – "I won't refine this one." Marvel: The Death Titan Thanos stood opposite Mu Yu in the starry sky, his terrifying aura shattering planets. In the DC universe, Harry Potter, American comic book universes, Pokémon, DNF, Ultraman, Men in Black... villains across countless worlds will face calamity.

[Congratulations, host, you have turned six! The strongest Naruto training system is now activated.] [Task 1: Become Tsunade's apprentice and become one of the new Legendary Sannin alongside your classmates Naruto and Sasuke.] "What kind of idiotic system is this? I'm already twenty-one! Naruto and Sasuke are my students! How can I become Tsunade's apprentice? Answer me!" [Task 2: Help your classmate Hinata Hyuga retrieve her scarf.] [Task 3: Doodle on the Hokage Rock with your classmate Naruto Uzumaki.] [Task 4: Defeat Sasuke Uchiha and dominate the Ninja Academy.] "I'm a teacher at the Ninja Academy! Is this kind of mission appropriate? I wouldn't do it even if I jumped off this cliff!" [Task Rewards: Yin Seal, Leaf Whirlwind, Super Beast Imitation Painting, Dark Travel Technique] "System, you win! I'm a genius who just turned six! Deep Blue! Let me see your limits!" Kitazawa, a nobody transmigrator, an ordinary Chunin, lived a quiet life teaching at the Konoha Ninja Academy to survive until the end. Then, at the age of twenty-one, a problematic system arrived, and the ninja world was never at peace again. PS: A lighthearted, invincible style. I already have two excellent books, "Infiltrating Konoha, Part-Time Hokage" and "Konoha: The Gu Master Creates the Hokage," which you are welcome to collect and read.

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.

I've arrived in the world of One Piece with the Tenseigan, and I'll be the freest person on this great sea!
