Detective Conan: As a Dark Wizard, I Am Really Not Kaito Kid

A young man who dies suddenly from overwork transmigrates into the world of Conan. He inherits the black magic book his parents left behind and becomes a wizard like Akako Koizumi. Raised by the distillery as a child, he becomes a police officer as an adult. He has no grand ambitions for the future. Since everyone longs for immortality, he'll go and see what eternal life is like. Along the way, though, he meets plenty of people and experiences plenty of things. Jinzou Nakamori: “Shimizu, I'm starting to suspect I'm Kaito Kid.” Kaito Kuroba: “That guy... He's my lifelong rival.” Conan: “Justice is defined by the law. Shimizu, you're too extreme.” Gin: “If it's him, I have nothing to say.” [This book is also known as I'm Just a Wizard, Not a Savior, You Come to Me with Cases the Police Can't Handle? Don't You Know I'm a Cop Too? and I'm Not Justice, but I Represent Justice]
