[Crossover] Where Should That Stray Dog Go?

[Romance will definitely make the characters OOC. Please read the synopsis at the very bottom to avoid surprises.]

Also known as [After Escaping Control, I Ran Into the Strongest Again]

Beixiaowen. That's his name.

He grew up in the Public Security Bureau's Special Division Against Demons and was very good at hunting demons. He raised his unrelated younger sister, Bei Qingqing.

Being a devil hunter was already hard enough, and then there was a kid to take care of...

But this was Miss Makima's mission, so he would carry it out.

Miss Makima?

Oh, she's the woman he loves most.

He hates being called a dog, but he can be Miss Makima's dog. Don't question it. Humans are hypocrites by nature.

Miss Makima gives him love and money.

He hates being saddled with a whole family. A mission from Miss Makima? He can put up with it. But wasn't that supposed to be Himeno and Aki's job? Why make him do it?

He hates white-haired brats in sunglasses. A mission from Miss Makima? He can put up with it. But there was no need to accept a mission protecting this kid, so why make him do it?

He hates missions where he's all alone. It's too lonely. A mission from Miss Makima? He can put up with it. But why make him deal with Mafia threats and spend time with the boss?

He gave up. In his dreams, there was a beautiful woman like Suiko, yet he fell in love with the King of Curses from the Heian era. His brain must be broken. Why would he dream something like that?

He accidentally became a young master's bodyguard? Fine, the pay is better than doing missions. But he doesn't want to be caught in the middle. Some fox-dog-cat combo? Nothing like that is happening.

He accidentally became a pretty boy's nanny? No pay. Fine, at least the guy has an adorable hedgehog-haired son. He's trying to steal his sugar mama? No such thing.

He accidentally became the childhood friend of an Italian Mafia boss? Fine, the kid is pretty handsome, after all. He's confessing his love to him? No such thing.

Makima: Wen-kun? He's a capable dog. I'm quite satisfied.

Sukuna: Huh? Did you forget you're wearing the dog collar I put on you?

The Strongest: Leave that Makima. I want to control Wen-chan too~ (pouting)

Seafood company owner: I'll protect you and help you escape her control. Please believe me!

Golden retriever: Come back to Italy with me! I'll cover your living expenses!

Notes:

1. The male lead is gorgeous, strong, and miserable (with a missing brain stem), and not slender (he can act cute).

2. A top who is strong on offense but weak on defense, and is into men and women. Probably a universally adored character.

3. Everyone has unrequited feelings for him. No CP for now.

4. A crossover mainly featuring Katekyo Hitman Reborn!, Jujutsu Kaisen, and Chainsaw Man (possibly more Reborn!), with The Disastrous Life of Saiki K. included.

5. A long, plot-focused story with no logic (interspersed with lots of daily life). No paid chapters. Updates will be slow, w.

6. There will be a high school boy sandwich, a black-and-white sandwich, a dark sandwich... Enjoy!

7. I'm writing what I like, so please understand if it's not to your taste. I'll try to fix anything unreasonable. If you like it, feed me with comments to keep my motivation upup XD
