When Shirahoshi encountered the shrinking lamp, she shrunk to a normal human size. When Shanks ate a Senzu Bean, he grew a new arm.

When Akainu drew his Ryuuka sword, Jakka, it ignited the sea. When Crocodile sat atop the Creation Engine, contemplating the future.

When Luffy opened the One Piece manga, he learned about the future developments.

Everyone was suddenly awakened to find that the sea had become completely unfamiliar!

Navy Headquarters: All Rear Admirals and above, get the chance to open cans!

The four emperors temporarily put aside their grudges and reached a consensus: let's get our hands on the jar first!

The Five Elders held an emergency meeting: We must stop Xia Wen from selling the cans! We must maintain world stability!

When Im awoke from his slumber and learned that there were several Nika Devil Fruit users in the ocean, he felt as if the sky had fallen!

The strongmen who emerged from the jar shop all headed towards the sea, solely to spread the word about the jar shop's greatness.

Thus, a new legend was born on the high seas: "Better to offend the Four Emperors than the Jar Merchant!"

Now... it's the era of big can opening!

Pendragon, who died from exhaustion after staying up all night drawing cards, finds himself reborn into the body of his waifu—"Mysterious Heroine x Alt"! Current progress: Marvel Cinematic Universe (Completed) — Tokyo Ghoul (Modified) — Fuyuki City (Modified) (Completed) — Academy City (Reversal) (Updating)

Higashino Yuu never imagined that the "cognitive reconstruction" ability he awakened after traveling to Academy City would become the ultimate cheat for building a harem. Saying "You're a little attracted to me" to Misaka Mikoto makes the Railgun's cheeks turn red as ripe apples. Mummifying "You want to understand me" while locking eyes with Shokuhou Misaki makes the Tokiwadai Queen's remote control quietly aim at him. Even a saint like Kanzaki Kaori can blush at the mere suggestion of "Come see me tonight." From Judgment Officer Hatsuharu to ANBU TEM's Mugino, from the mage-minded Index to the one-eyed demon god Othinus... If he so chooses, rewriting the perceptions of girls and making them utterly devoted to him is a matter of thought. Higashino Yuu held his forehead, looking at the group of beautiful girls surrounding him, sighing with both helplessness and excitement, "I told you not to push... Okay, whoever kisses me first, I'll be theirs tonight." This is the story of a man who uses his powers to forcibly conquer every goddess in Academy City, turning his "harem" into a "settings manual"—after all, for him, making beautiful girls fall in love with him is easier than unscrewing a bottle cap. PS: This book is more about daily life, with more peach plots in the later stages. I'm not a fan of meticulous research or rigorous settings, so please don't criticize me if you mind.
