Rebuilding the Vongola Family in the World of Detective Conan

Before the joking last words could even be finished, the bomb that had suddenly started counting down was kicked through the glass curtain wall, exploding in midair with a flash of fire and smoke. Silver hair, green eyes, and an air of rebelliousness: the boy irritably raked a hand through his hair. "Hey! Are we under attack?!" Looking at the smoke-filled floor, the curly-haired police officer tried to ignore his teammates' protests and go find his childhood friend, but someone grabbed his leg. A child in a cow costume with a fluffy, explosive hairstyle nimbly climbed onto him. "Lambo-sama likes shiny, shiny fireworks." As soon as he finished speaking, a pink grenade rolled out of his hair... The undercover trio were led into a secluded room. The silver-haired man sitting across from them had a chilling presence, and his gaze was full of scrutiny. The three held back their questions, only to see a cheerful boy walk in, utterly out of place in the gloomy surroundings, a baseball bat slung over his shoulder. "Huh, are they the teammates you arranged for me?" The little detective, absorbed in solving a case and having forgotten his date with his childhood friend, rushed over. What he saw was Xiaolan, her back to him and her arms wrapped around something, while a boy stood in front of her, waving his arms as if he had seen something terrifying. The little detective ran with all his strength, worried for Xiaolan's safety, only to see... The Chihuahua in her arms. And the person who had been so frightened he'd fallen to the floor, waving his hands frantically. "Waaah... How scary..." Meanwhile, at a school somewhere in Beika Town, a tall, handsome black-haired boy wore a vicious smile. "You're all clustered together! I'll bite you to death!" A frail girl in a white dress and an eye patch collapsed weakly at the entrance to the police headquarters... A white-haired hedgehog with bandages wrapped around both hands ran down the road, full of passion. "To the limit!!" [Previously:] 1. Everyone has a secret identity, and none will be exposed. 2. I've only watched the Katekyo Hitman Reborn anime, so characters may be out of character! 3. The author's logic isn't great. If that bothers you, proceed with caution! Proceed with caution! Proceed with caution!!! 4. All the anime characters will appear, including Fran, Uni, and Byakuran. 5. Everyone is single except the canon couples (Shuichi and Akai have a sibling-like relationship). 6. The protagonist has almost no presence. The secret identities do all the acting, so you can read this as a group transmigration story. 7. I'll give advance notice if anything comes up. I won't suddenly disappear. Theme: The world is real, and every sacrifice is worth it.
