[Crossover] Baby Gacha

[Updated daily. The cover really doesn't depict a girl. The protagonist is just a pretty fairy-like man. Please stop asking, or I'll have to kill myself, sob.] Shimizu Kazuya was an utterly ordinary office worker, living a quiet but very stable life. That is, until one day he pressed the button on a capsule toy machine. A flash of red light, and a little one popped out of the capsule, blinking his big eyes. In a babyish voice, he said, "Hello, I'm your boyfriend." Shimizu Kazuya: ...I have no words. The new dad had to jump straight into the job and start raising the kid. Fortunately, the kids were all obedient and considerate, and never caused trouble. Dad was very pleased. ...Or so he thought. "Chuuya, let's talk this out. Don't hit your little brother!" "Akutagawa, Dad knows you like your big brother, but we really can't afford to send you two to Germany for treatment!!" "Dazai, stop using your charms on people! The girl who visited last week has already walked around the neighborhood three times!!!" "Ranpo, you can't secretly hide the sweets. You've had too much sugar this week!!!!" "Squeak~" "...All right, one last piece." Shimizu Kazuya smiled bitterly: The kids are all adorable, and they say the sweetest things. I love raising kids so much QAQ *A cozy, everyday child-rearing story* *Just raising kids, with absolutely no romantic undertones between Dad and the kids (important)* *Crossover with Bungo Stray Dogs and Demon Slayer, also featuring JoJo Part 5 and Detective Conan. Demon Slayer is set in a modern AU.* *Thanks to my bestie @Weimu Denghuo for the gorgeous cover! Love you, mwah mwah mwah!* Theme: A happy life with the kids
