Cephalosporin Attacks the Red-and-Black Reversal World of Detective Conan

[Chapter comments are open. 50% anti-theft protection. Come check out the character cards𓀠 Read the notes below first. If you get blindsided for not reading them, that's on you. (Seriously)]

As you can see, this is a cephalosporin. This antibiotic has gained sentience and transmigrated to another world called [Darkened Deduction]. A being calling itself the System shows up and asks him to become a savior, wiping out the excessive forces of evil and restoring balance to the world.

The System is full of hope: [You're the most accomplished cephalosporin in the anthropomorphized-cell world. Surely you can quickly clean up this world crawling with villains!]

After hearing the System's explanation, the cephalosporin understands everything.

The immune cells in this world are barely holding on, while the miscellaneous germs named after alcoholic drinks swagger around unchecked. It's a very harsh world, desperately in need of an excellent cephalosporin like him, one that reacts strongly with [alcohol-related miscellaneous germs].

Cephalosporin: "No problem. I can keep killing germs here until the New Year."

System: [Great, great! What's the plan?]

Cephalosporin: "I'll start by giving that blond, dark-skinned germ some hot water. I plan to scald him to death and disinfect him that way."

System: [?]

Round one: Cephalosporin chooses physical sterilization. Some time later ↓

Cephalosporin: Hot water, you...

No. 2 Cat-Eyed Germ: *Gulp, gulp...* Finished it. Thanks for always looking out for me.

Cephalosporin: ?

Round two: Cephalosporin decides to poison them. Some time later ↓

Cephalosporin: I poisoned you.

No. 1 Golden Retriever Germ: Don't say that. I don't want to start having feelings for you. "Looks away.jpg"

Cephalosporin: ??

Round three: Cephalosporin learns from his mistakes and goes straight for a good fight.

Cephalosporin: Let's go one-on-one in the training room tonight.

No. 3 Purple Bacillus brings along No. 4 Little Jinpei Germ: Aww, can't the three of us do this together? Nothing matters more than us living happily together~

There are plenty of ways to kill germs: drown them, scald them with hot water, fight poison with poison... But after a while, Cephalosporin feels that none of them are working very well.

To know his enemy as well as himself, Cephalosporin sneaks into a team-building gathering of the miscellaneous germs he's been spending time with for a month, ready to hear what they think of him.

No. 4 Little Jinpei Germ speaks up: "Why have all you guys come back? Weren't you supposed to be investigating him?"

No. 1 Golden Retriever Germ looks away: "Sorry. Whenever I get near him, my heart races and my face gets hot..."

No. 2 Cat-Eyed Germ lowers his gaze: [He even reminds me to drink hot water every day.]

No. 3 Purple Bacillus waves both hands: "Jinpei, you know how it is! I was ordered to investigate him, but before I could crack the case, my heart cracked first!"

No. 4: "...Has he been looking out for all of you lately?"

Mysterious No. 5: "...What do you mean, all of us?"

No. 6, passing by, cuts in forcefully: "Sorry, I'm here to break up this family."

Nos. 1, 2, 3, 4, and 5: ?!

Cephalosporin: "...Did the drugs I gave them mess up their brains?"

System: [How am I supposed to know? Wait! Why is the balance progress bar almost full?!]

His silver-haired childhood friend, who receives five pledges of allegiance (applications to reform) in a single night: "...Hah. You're planning to take all five of those unregistered people away, too?"

[Reader's Notes]

1. No CP, and no romantic developments of any kind. He'll whisk away all the darkened characters and Red Pianos and take them on a world tour. Expect plenty of misunderstandings and melodrama. Cephalosporin's logic and perception are those of a cephalosporin. Direct contact between real liquor and a cephalosporin (skin-to-skin contact; contact through clothing doesn't count) causes a disulfiram reaction, with severity depending on the amount.

Mild symptoms: flushed face, dizziness, rapid heartbeat, palpitations, and chest tightness.

Moderate symptoms: difficulty breathing, abdominal pain, and headaches.

Severe symptoms: shock or sudden death on the spot.

You can also guess who's darker by their reaction. (nods)

2. The main setting is the darkened deduction world. There are lots of darkened characters, so see the story for details. Cephalosporin is based on a small cell; you don't need to have read it to follow this.

3. I started this book to relax, so I don't accept writing advice. If it's not your taste, you can stop reading partway through. Don't force yourself to read it just to come yell at me. Also, one earnest plea: please let character cards have enough room for text!!!!!!!

---Next Novel's Blurb---

Good evening. I'm Hoshitani Raio, a member of the Vongola's special assassination squad, currently undercover in the Port Mafia. I fell in love at first sight with the green-eyed black cat at the detective agency next door, and I'm about to pursue him passionately--

But there's one problem: my ability is △Love (Three-Person Love).

Parenthesis: passive ability. End parenthesis.

Whenever I say something romantic, it randomly reaches someone else. Whenever I give a gift, copies appear somewhere around the globe, each thoughtfully labeled with my full name...

No, that's not thoughtful at all! If this damn ability wants to kill its master, it should just say so. Just look at the people it randomly picked!

Unfold ↓

[The Mad Dog That Doesn't Bark

Yokohama's Songstress

Bandage Dispenser

Pineapple Can

Marshmallow Alien

Local White Qilin

Kind Russian...]

Wait, that list of terrorists keeps randomly messing with my love life. In a fit of rage, I--!

Got mad for a moment.

Still, to salvage the situation, I decided to shut away my fragile heart and add an excessive dose of sharp-tongued tsundere traits to my persona. That should keep away the people bewitched by [Three-Person Love], and I hope the person I'm pursuing will discover the love beneath my venomous words.

Ranpo is so smart, surely he'll figure it out!

Raio: ...He will, right?

Ranpo: (munches red bean paste)

Raio: Is he listening?

Ranpo: (rips open a bag of chips)

Raio: ...It's over. Ranpo really doesn't understand what I'm saying! Aaaaaah!

Ranpo: Hey, come open this ramune for the great detective!

Raio: !! Woof, woof--cough... A great detective can't even open a bottle of soda? Honestly, what am I going to do with you? (pop) (That's just the sound of opening the soda.)

[Reader's Notes]

1. The main pairing is Raio/Ranpo. A sweet, fluffy, one-on-one romantic comedy about a couple. Other characters, especially the villains, may have delusions of their own importance.

2. A crossover with The Disastrous Life of Saiki K. and Katekyo Hitman Reborn! Any out-of-character moments are my fault. Finally, feel free to bookmark it in advance~ Mwah!

Theme: Growing together through love and mutual support
