After traveling to the world of anime, Hikage Miyauchi obtained a magical diary. As long as he wrote in it every day, he would get rewards.

But he had read diary online before traveling, and he knew that what he wrote would most likely be seen by the heroines of this world.

As a salted fish with no ambition, Hikage Miyauchi immediately decided to be a pure fun person in this world.

"What era is it? Who still writes traditional diaries?"

"No one is really willing to write their true feelings in a diary and then be watched by countless heroines, right?"

"My mother told me that this world is very dangerous. Boys must protect their privacy when they go out, so don't think about coming to me. After all, I am a man you will never get."

As Hikage Miyauchi continued to write in his diary, an "Avengers Alliance" composed of heroines who could see Hikage Miyauchi's diary was quietly born.

They gathered together for only one purpose, that is, to find the owner of this diary and ravage him inhumanely!

Has it become the "humanoid self-propelled nuclear bomb" that AST and Academy City are fighting over?

The worst part is, Yukinoshita Yukino actually asked me to write an apology for blowing up the gymnasium! ? "

Hoshikawa Taku, who traveled to Japan due to the sudden death of his black-hearted boss's "PUA", was bound to the [Black-hearted Agent System]. The more "black-hearted" he was to the girl idols he signed, the better rewards he could get. So... he signed Toyokawa Shoko with a black-hearted contract with no base salary and 90% profit sharing. He signed Hiroi Kikuri with a contract of "free food, accommodation and enough alcohol". He signed Takamatsu Tomo with the condition of "forming a band for life". He signed Hoshino Ai with a verbal contract of "teaching you what love is"... When they learned about the contract conditions, all the girl idols scolded him for being a black-hearted agent. But when Hoshikawa Taku pushed the contract in front of them, they signed the contract honestly one by one. There was no way, who made him offer conditions that they could not refuse... Hoshikawa Taku said: I am the one who lost money by signing with you, and every penny of hard-earned money I earned from you is what I deserve!

Traveling through the world of Soman, Nakano Yuu starts with the [Oldest God Killer System], completes the system tasks, gets the number of draws, draws the power of gods and various artifacts!

Just when Nakano Yuu fantasized about hunting down the God of Disobedience and becoming the strongest demon king, he didn't expect that this was actually a weird world where monsters and weirdness coexist? ! !

Fortunately, he got the [Ten Powers of the God of War] and the holy sword Juvayus at the beginning.

Facing five sisters with different personalities, Nakano Yuu originally planned to be the only demon king in the world and enjoy life, but he didn't expect...

The second sister Nino went home from school and was haunted by a cursed female ghost named "Shirai".

Just after rescuing the second sister, classmate Gui Yanye suddenly got involved in a weird story called "Sarumu"!

After finally dealing with the Sarumu, a god of disobedience was suddenly summoned above the school.

After finally dealing with the God of Disobedience, I thought life was like this, but a girl who claimed to be able to see "spirits" suddenly asked him for help.

Looking at the different girls around him, Nakano Yuu was silent.

Is there something wrong here?

My name is Imazumi Rinnaeus, and I'm a transmigrator.

As a transmigrator, I naturally came equipped with a golden finger system.

My system is called the Dream Performance System. As long as I complete performances according to the script, I can receive rewards in the form of "tags."

Those max-level attributes, talents, skills, and even tags for health and longevity look truly enticing.

However, this damn system took over a decade just to activate, and the first script it gave me left me speechless.

Because this script... isn’t something one person can complete alone. It requires the cooperation of several girls.

For heaven’s sake, even in open-minded Japan, what decent girl would agree to this kind of script?

...

"My name is Nakano Ichika."

"My name is Nakano Nino."

"My name is Nakano Miku."

"My name is Nakano Yotsuba."

"My name is Nakano Itsuki."

Today, they accepted an invitation from a certain "great system." In order to achieve their respective goals, they decided to seek out someone with the surname Imazumi and perform the script together.

It’s just that this script... is way too embarrassing...

"Rainy Night, Overpass, Maybach."

Crash.

...

When sitting alone, he often caught himself thinking about her—the girl who had shadowed him for years. He’d imagine her barging into the restaurant, drawing every gaze, then plopping down beside him, propping her chin on her hands as she stared into his eyes.

"Buy me a cola," she’d say.

But tonight, to his surprise, another girl actually did sit next to him.

...

Blue hair. Delicate. Radiantly sociable. A checklist of desirable traits.

Yet when it came to love, she was bafflingly cowardly.

Even his unluckiest junior never got to drink their senpai’s leftovers—but Banaumi did it without trying.

Too scared to confess. Clinging to "I’m fine" while heartbroken. Binge-eating after rejection. When urged to fight for her feelings, she’d just whisper, "I hope they’re happy."

He kept seeing that other girl in her—until he blinked, and a stranger’s face stared back.

A stranger who wasn’t even the same gender.
