My name is Yotsuba Mahiro, a time traveler.

Sent to the Demonic World by an alternate-world teleportation ambassador, I became a Adjustment-Type magician of the Yotsuba clan.

Besides being born with eyes capable of replicating all forms of magic and physical techniques, perhaps my greatest supporter is my cheap mother, Yotsuba Maya.

After fifteen years in the gloomy Fourth Research Institute, my cheap mother suddenly gave him a crucial task.

"Although you're a Adjustment-Type magician of the Fourth Research Institute, you're also my child."

"So, it's also your duty to produce a worthy heir to the Yotsuba family."

It's just about carrying on the family line, a simple matter. Is the bloodline of the Ten Master Clans and the Hundred Houses enough? What if

I add your sister Miya? What if

I add the lolita from the Black Bullet world?

What if I add the assassination group from the Zelda: The Sisterhood?

What if I add a singing diva from Guilty Crown?

...

After traveling through ten worlds, he asked Maya again.

"Is that enough now? If not, I can add more!"

Among penguins, which value loyal love and adhere to monogamy, emperor penguins are the most unusual. It's not that they're unfaithful in love, quite the opposite... "So what does this have to do with me?" Fujiwara pushed his glasses up as he watched the ex-girlfriends slowly approach. "I don't change wives every year." "Shut up! You scumbag who changes wives every week!"

(Holy Armor: This book is set in a modern Tokyo worldview, involving MyGO, I recommend, Lonely Rock, etc. It is also a harem story with a male protagonist, so please do not read if you don't like it.)

Lu Yu, seventeen years old, is handsome and has excellent character and academic performance.

After traveling to a hodgepodge of Tokyo-style anime, Ruyu obtained a system that can train heroines from various worldviews to become masters in the field of music and help them solve their problems.

Thus, Lu Yu began his journey to become a gold medal mentor.

Hoshino Ai, Toyokawa Shoko, Goto Ichiri...

With Lu Yu's help, one girl after another overcame difficulties and achieved success. However, when the girls became successful and wanted to repay him, he had already hidden his fame and left quietly to go to the next heroine.

"You said I was the best idol in the world, so why did you leave?"

"We agreed to be in a band for life, how could we allow you to escape?"

"I won't let you escape. Even if I have to chase you to the ends of the earth, I will find you!"

Lu Yu: “???”

It's just a system task, don't take it seriously.

Raymond Lam was teleported to the second dimension world and

started his bulldozer life in the porn world.

In High School of the Dead, he pushed the busty teacher Marikawa Shizuka at the beginning, and

Raymond Lam got the dragon enhancement.

After that, Miyamoto Rei, Busujima Yako, Takagi Saya,

Minami Rika, and even the married woman Takagi Yuriko, none of them can escape.

In Cross and Vampire, as long as they are cute girls, Raymond Lam will take them all.

Dongfang You is reborn.

Good news: This is the second dimension.

Bad news: This is the other world.

Good news: Dongfang You has awakened the system, and he can become stronger as long as he saves the heroine.

Bad news: There are yellow-haired people and minotaurs everywhere.

Well, since this is the other world, is it okay for me to have sex with the heroine while saving her?

ps: daily anime, battle anime, and other things...

My name is Fujiwara Seiji, a transmigrator. What I love most isn't saving the world, but admiring the helpless yet beautiful sight of those arrogant heroines falling into the abyss. When the black-stockinged upperclassman, Kasumigaoka Utaha, took off her stockings in front of me for three million yen in surgery fees. When the blonde loser, Eriri, knelt down begging me to invest in her dreams. When the icy beauty, Yukinoshita, walked into my room to rebel against her family. Only then did I realize how interesting this world truly is. Hero? Savior? No, I just want to be a… behind-the-scenes mastermind who controls the heroines. [Friendly Reminder: The protagonist of this book is loyal to his own desires; those with a saintly heart should avoid this!]

This world is like a sieve, with things falling from anime, novels, and games every day. At first, it was just items falling, but then monsters started falling into this world, and everything changed. The barriers between dimensions seemed to vanish in that instant, and an apocalyptic catastrophe descended. [World Administrator's Log] [January 2nd: Found a portal; distance is no longer an obstacle.] [March 15th: Found a branch from the world's tree, along with a Goddess of Wisdom. I planted her in my backyard; she can keep me entertained.] [May 17th: Found a Heroic Spirit; she is the Queen of Britain, and she has a huge appetite—she can eat ten people in one meal.] [June 23rd: Found another Heroic Spirit; she is a saint from France.] [Found another person today, and it's a post-apocalyptic girl...]

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.

Suddenly, a beautiful silver-haired girl appeared before him. She said he'd awakened the ability to "slip," and she wanted to take him away and protect him. She also wanted him to transfer to Hoshi no Kai Academy. Wait, isn't this silver-haired girl Nao Tomori? Aren't there more than just Kaguya-sama: Love is War, Quintessential Quintuplets, and Charlotte here? ... Fortunately, he's no pushover. His abilities aren't limited to the one he got from "In Another World with My Smartphone"—slipping—but he also has abilities from "Cooking Master Boy" and "K"... (Are daily battles 50-50? Quintessential Quintuplets and Kaguya have everything. Conan's behind-the-scenes boss is exactly as some experts had guessed. I'm impressed!)
