Detective Conan: Ace Attorney

My name is Ryuichi Naruhodo. On the surface, I'm a lawyer, but in truth, I'm a transmigrator with a System. After transmigrating, my job is to defend the innocent and take their cases to court to prove they are blameless. This should have been the normal course of events for me as the protagonist of the Ace Attorney series, but the timeline has gone haywire. At first, I thought it was because I saved Chihiro Ayasato from the start, causing a butterfly effect that threw the world's plot and timeline into disarray. It wasn't until later that I learned about the legal world's famous "Invincible Queen, Eri Kisaki"! That's when I finally realized this was the scientific timeline of Detective Conan! My main quest had only just begun! Not long after that, I, a lawyer, appeared in the newspapers again with a new title: "Ace Detective"! From then on, the world of scientific mysteries had not only a blue-suited grade-schooler who liked to say, "The scheming frog keeps rubbing your belly," but also a blue-suited, spiky-haired guy who liked to slam the table and yell, "One jin of pears!" (Objection!)

(The author is an old bookworm who's run out of novels to read, so he wrote one for himself. Multiple female leads, some couples broken up, with Detective Conan as the main world.)
