Yokohama Kindergarten, Launch!

Ugly romance. Don't read.

"You know? In our line of work, you have to have a heart of stone," the young man said gloomily.

"So..."

"You know? The biggest taboo in our line of work is falling in love with a client," Ke Yu said sadly.

"So..."

"You know? In our line of work, " "I don't know!"

The System flew into a rage. "I just want to know, what does this have to do with you opening a kindergarten?!"

Ke Yu shrugged. "Opening a kindergarten? Are you planning to let all those brats die, or do you want me to die?"

"System, don't take this the wrong way, but what were you thinking when you bound yourself to me?"

The System tried to stay calm. "Host, don't worry. You'll be playing every single child. That's right, you're exactly the talent we need."

"For real?" Ke Yu felt around in his pocket, pulled out a crumpled piece of paper, and unfolded it. "I'm mentally ill, you know. The hereditary kind. Make me play them and I might split into different personalities in a second, just so you know."

"...If you don't agree, I'll bring you back to life."

The System, a thirty-year veteran fish killer, spoke coldly and mercilessly.

"No problem!" Ke Yu immediately changed his tune and agreed wholeheartedly.

That day, Ke Yu became a kindergarten principal, ordered by the System to establish a kindergarten.

The young man was shocked (and delighted): "What do you mean, build a park? Is that the kind of person I am?"

The System, which had asked him to establish a kindergarten: ...

Later, in a little kindergarten in Yokohama, Ranpo in the younger class and Go-chan in the older class fought over cake.

A Russian boy in the older class and the cult leader, Geto, teamed up to research "And Then There Were None."

The daycare teacher, Mori Taro, had everything completely backwards.

The language teacher, Dazai, was beaten up by students and colleagues every day for some reason. He made a habit of skipping class to find Oda Sakunosuke in the older class for comfort.

And when everyone came looking for Ke Yu, the principal of the Yokohama kindergarten,

the man silently pulled out his psychiatric evaluation: Mental illness (hereditary).

System: "...You're actually ill?"

Ke Yu blinked innocently and casually pulled out his family tree. Mother (ill), father (ill), paternal uncle (ill), distant cousin (seriously ill)...

Looking as far as the eye could see, there wasn't a single person without a problem.

System: ...I underestimated this.

Here's another upcoming book: This Is My Secret Identity, Why Are You Messing with Him?

Mechanical Intelligence No. 10 was an office drone, and one with a terrible boss. When a batch of secret identities belonging to the Space-Time Administration went missing, his shameless superior pinned the blame on him.

Forced to retrieve them, S-rank System No. 0010 already had a hard enough life, but now people were interfering with his missions too.

Secret Identity One: Water Spirit, Bihai.

Taking advantage of Yokohama being a coastal city, she went after the Port Mafia from the start and dragged countless people into her waters to play with her.

At last, after he had racked his brains to complete the scenario and was ready to retrieve the secret identity, he was stopped by the Port Mafia's Gravity Manipulator.

"How much longer are you going to keep her locked up, you bastard!"

Secret Identity Two: Light Spirit, Hui.

Helping people was in her nature. The Light Spirit went around granting wishes and bringing the dead back to life, plunging Yokohama into chaos.

After No. 10 finally found her, he worked hard to sort out the mess. But just as he was finally able to retrieve her, he was stopped again. A red-haired man stood firm, protecting a group of children behind him.

"She's not the one at fault. The human heart is."

Secret Identity Three: Dark Spirits, Youming and Huiyi.

The two mischievous troublemakers secretly snuck into the territories of various organizations to play pranks, putting all of Yokohama on alert.

But when No. 10 arrived to retrieve them, the Agency's great detective protected one with each hand.

"Locking them inside to guard the Book is too much! The adults are all terrible!"

Secret Identity Four: Mist Spirit, Fulan.

She loved playing games, and when she met Tatsuhiko in the night, the two hit it off. A thick fog began spreading through Yokohama.

As expected, No. 10 found himself facing a white-haired man blocking his way.

"What's wrong with wanting to get our own treasure?"

Listening to the man's question, No. 10 felt extremely miserable. Why treat an office drone like this?

A new crisis had recently appeared in Yokohama: the Book, said to be able to grant any wish, had gone missing.

As one sealed person after another escaped, they gradually learned the truth behind the Book's seal. It was built from one living life after another. The women had become the seal, trapped inside the Book forever in exchange for their freedom.

Looking at the boy who ruthlessly carried out the sealing, everyone in Yokohama was furious. Why treat them like this?

Content warnings: The secret identities are the protagonist's cosplays, so out-of-character portrayals are unavoidable.

Jujutsu Kaisen and Demon Slayer appear very little. This is set in the Bungo Stray Dogs world, with Demon Slayer and Jujutsu Kaisen characters making guest appearances.

The main plot focuses on the protagonist, and there is little interaction between the secret identities.

Theme: Life is beautiful
