Anime Crossover: How Many Cheats Do You Have?

[Main fandoms: Bungo Stray Dogs, Detective Conan, Katekyo Hitman Reborn!]

[Raising kids + max-level powerhouse + a hint of a harem + no romantic pairing in the ending]

After arriving in Japan, Guanyue Li was bound to a system calling itself the "Yokohama Rescue System," System 0407.

She saw right through its lies.

In the end, System 0407 confessed everything: it was an ability-imbued object, the [Book].

The [Book] had accidentally broken through the barriers between worlds and seen glimpses of other parallel worlds.

Its dearest [Bookmark] had somehow ended up in an orphanage, where it was bullied by a gloomy mushroom-haired director and a group of nasty kids.

That alone was enough to make the [Book] furious.

But then the Special Division for Unusual Powers went and lost one of its [Pages]?!

The [Book] had had enough. It ran away.

With information provided by the kind Vongola Rings, it found Guanyue Li, who had come to Japan for a vacation.

After hearing what it had to say, Guanyue Li agreed without much hesitation. She loved adorable human children, especially those under ten.

And so the future big family, currently a small one, welcomed its first little one: Nakajima Atsushi, with white hair and purple-and-gold heterochromia.

A year later, a huge explosion brought the second little one into the family: Nakahara Chuuya, with orange hair and blue eyes.

The first and second are here, so how far behind can the third be...

At the [Book]'s urging, Guanyue Li also established a detective agency.

But the agency was on the second floor, so, to make eavesdropping on gossip more convenient, she opened a convenience store on the ground floor.

A Western-style restaurant, a clinic, a clothing store, a dessert shop...

Guanyue Li: Retiring in Japan really was a great choice!
