(The author will usually reply if there are any questions) During the war at the top, Sengoku held his forehead with one hand and looked at Ace who had been rescued: "Garp! Your grandson is really a headache." Garp, who was pressed to the ground by Sengoku, said: "Sengoku, just hold me like this, otherwise I will not be able to help but thank the guy who saved Ace."

I've traveled through time, but not just one world. When awake, I'm in the world of Souman, and when I'm asleep, I'm in the world of Harry Potter. But that's not the most outrageous thing. What's outrageous is the restraining power of the Souman world: Gaia, who enjoys picking up random things in the World Sea. To prevent the daily Souman world from being destroyed, Hanyu Genichi reluctantly picks up his wand and cleans up Gaia's mess. From the T-virus to Kabane, to ghouls, gastrula, and later, giants, they don't care about the lives of humans at all, do they? Gaia, you really only think about yourself.

Some people may say that 1+1=2, but Su Ye actually doesn't think so, because getting along with one self and another self is even more enjoyable than the inner treasury being secretly replaced by a brother in the middle of the night.

You ask what's so enjoyable? Su Ye will only answer that he doesn't know.

"WC, why is Sasuke spiraling up to the sky?" Su Ye pointed to the sky and exclaimed.

"You did it." The girls said.

Madoka: "The pervert who wants to lick someone's feet when they first meet is really perverted."

Gokawa Shiori: "Actually I can do it, Su Ye!"

Akemi Homura: "Obviously I came first, woo woo woo."

Su Ye: "Where are we going today?"

Natsuki arrived in the world of Naruto. He chose to let go of the savior complex, respect the fate of the chosen one, and live only for himself.

Naruto: Sasuke!

Sasuke: Naruto!

Sakura: Stop it, you two! Don’t fight anymore!

The rain poured relentlessly. Off to the side, Natsuki snacked on sunflower seeds, casually handing some over to his girlfriend, Tenten.

Pain: He deflected my Shinra Tensei!

Obito: I just wanted to create a world with Rin... but that bastard Natsuki said “If there’s Rin, there has to be Kakashi,” and made me watch Kakashi unleash Kirin. Be born already!

Six Paths Madara: I acknowledge Natsuki as the strongest!

Black Zetsu: Natsuki, you bastard! Get your foot off my mother’s head!

Natsuki: Just Eighth Gate, Hiraishin, and Sage Mode—and I’m already the strongest in the shinobi world? Really?

【Funina + Naruto + Transformation + Single/Hundred + Bad Woman + Heartthrob + Genius】 She accidentally traveled to the world of Naruto and turned into Funina, a popular character in a game in her previous life. The three seafood she brought with her could only be viewed like pets. She thought she could only eat and wait for death as a salted fish waiting for the protagonist to save the world, but she accidentally activated the Heartthrob System. As long as she is liked by the audience in another world, she can gain favorite points, so as to add points and upgrade. As for being liked... this is really a professional match for her. "Naruto, I believe you can become Hokage, starting from when you stated this dream." "Sasuke, although I haven't experienced the same thing and can't fully empathize with you, no matter revenge or anything else, I will support you, because we are companions." With her superb "acting skills" {actually, I think so in my heart}, Funina naturally became the audience's favorite object, but as time went on, gradually, the audience suddenly found that the considerate white moonlight in their hearts was a little bit wrong. "The strongest in water escape, Senju Tobirama? He is just an ordinary person who was born in an era without me." "Uchiha Madara, what a delightful battle! I hope you can dance for a while longer." The huge contrast between the two did not make the audience feel uncomfortable, but made them like it even more. ... Finina: It is not easy to be hated by others~ Protagonist: Finina
