Can You Solve Detective Conan Cases With the Ability to See Ghosts?

[The blurb has been archived.] Koya Rikka is a rookie detective in the First Investigation Division. Her personal search keyword is: seeing ghosts. (Literally seeing ghosts.) Koya Rikka spends her days working overtime with her tousle-haired partner, solving cases and writing reports. Then one day, she wakes up to find her partner's ghostly companion behind her. The ghostly companion claims to be her partner's childhood friend. Koya Rikka: "!" Is this where her supernatural detective story begins? And so Koya Rikka begins her main quest, an endless stack of supernatural detective missions nested one inside another. She uses her ghost-seeing ability to solve cases faster and helps her colleagues outpace the detectives. She pretends to betray them for a mission and nearly gets sent to jail by her partner. In short, this is the story of Koya Rikka grumbling her way into becoming a hero (the good guys) who fights a dragon (the bad guys)! Koya Rikka: Thank you, seniors, for teaching me and helping me! You're my role models and teachers, and you're all my dads! The tousle-haired guard dog: Who wants to be your dad?! Is there no romance switch in your head or what?! Victims of a crumbling worldview: The Grim Reaper detective kid whose cases keep getting stolen: "I have to say, I'm impressed. Officer Koya actually said the victim told her who the killer was? That's ridiculous! I wouldn't believe that! Until... I saw a half-transparent man appear behind her. He looked in my direction and told me not to say anything... That day, my worldview collapsed." The tousle-haired partner who keeps dying of embarrassment: "My partner is great at solving cases, but there's something wrong with her brain. She keeps saying that something important to me is in her hands. I didn't take her seriously and kept teasing her. Until... my childhood friend, who really was important to me and was already dead, appeared behind her and told me to stop picking on her... That day, my worldview collapsed." The elite undercover blond waiter: "I'm a three-faced undercover agent, enduring humiliation as I make my way through the darkness. One day, I found my childhood friend, who'd already kicked the bucket, beside my junior colleague. I tested my junior in every way, and even considered driving a wedge between her and her partner from the same class. Until... my childhood friend came to see me and turned half-transparent right in front of me... That day, my worldview collapsed." The unlucky members of the Black Organization and others: ...We don't want to talk. Some of us get arrested, some get killed. You people play dirty, sending out a weapon of mass destruction like this! The cast keeps growing... [Important: The main fandom is Detective Conan! The few crossover fandoms won't affect your reading. Some plot points have been changed. Everything has been heavily altered! The main story is told in third person. The CP is tentatively set to be sweet. The girl has A-rank strength and speed, and can see ghosts. None of the characters have exes! An extremely sweet, satisfying story. If anything doesn't make sense, blame me. Please don't bully little Rikka.] [Upcoming story blurb] ↓↓↓↓↓↓ [The blurb has been archived! Keep reading for a surprise. Now open.] Retired, Then Rehired: My Childhood Friends Are Now Fake Liquor -- When Bourbon and Scotch's childhood friend meets Zero and Hiro! (I) Yes, as you can see, I'm dead. But not completely dead yet. Because the second after I died unexpectedly, I got bound to a System. It said it could give me a chance to start over. But the price was that I had to save the world. Me: Thanks, but I'm not exactly eager to live again. (II) Just kidding. Who'd want to die if they could live? I've still got two incredibly difficult childhood friends waiting for me at home! I'll skip the details in between. Anyway, I came back to life. One day, I went out to buy milk tea, and the moment I opened the door, I saw my blond childhood friend, who'd been away on a business trip for three days. The guy was even pretending not to know me. Me: Wow. You've really got things backward, huh? (III) [Ding! A bug has been detected in the source world. A re-employment invitation is hereby sent to Agent 04.] [Host, please confirm your mission as soon as possible. If the source world is destroyed, all branch worlds will disappear along with it.] And so, I was forced out of retirement and rehired. The kind of situation where if I don't go, we're all done for. A mission list longer than my life itself on the display. Two bottles of fake liquor who look exactly like my childhood friends standing right in front of me. As a frail, sickly person, I feel a little helpless. Me: Taking a leisurely solo trip through another world? That's pretty awful. [Important:] The main story is told in third person. I'm terrible at writing blurbs. The story starts with transmigration, right into the face of a Zero who looks just like my childhood friend. Little Si Bai's original world is a parallel world where some people have switched between the good and bad sides. The source world is the original, fundamental world. Little Si Bai is very smart and the mastermind type, though the author may not be. I'll add more if I think of anything. Theme: Beneath the peaceful, stable surface, someone is carrying the burden for you.
