[Crossover] Ever Since Mao Lilan Became Small, I've Been Her Male Nanny

Blurb: [Temporarily on hiatus] Kudo Shinichi opens his eyes and finds himself back at the amusement park, before he shrank. He swears he'll never fight the Black Organization again (?). He made Ran wait in vain for ten years, only to discover that Ran has shrunk too! Kudo Shinichi looks at the tiny Ran, who doesn't even reach his knees, her eyes sparkling: "...So cute!" And so Kudo Shinichi's daily life turns into looking after a kid, raising a kid, and keeping a kid company. But what's with all the little kids who keep showing up one after another? They even refuse to leave his house. Is he really going to become a professional male nanny? Raising kids is skilled work, and it takes money, too. Kudo Shinichi sees his allowance dwindling and turns his gaze toward the little ones, a meaningful smile appearing at the corners of his mouth... Naruto: "I can write books..." His inner thoughts: I've secretly read several of Teacher Kakashi's Make-Out Paradise books! Sesshomaru: "I... can understand animals and help you solve cases..." His inner thoughts: Damn it! How could this esteemed prince have fallen so low! Illumi, who already considers Kudo Shinichi's money his own: I need to come up with a reasonable plan to make the little ones earn even more money for me! Phantom Thief Kid: "I hear there are things called internet celebrities?" The little ones: "Waaah!!!" Kudo Shinichi sees the number of zeros in his bank account growing and smiles... P.S. This is a slice-of-life story, with no logic and plenty of headcanons. Everyone, feel free to comment and add it to your collection! Theme:
