My name is Kamidou Chiyo. I used to be a brilliant detective… ahem… sorry, wrong script… let me introduce myself again…

…Once a teen from the Heavenly Kingdom, I died and reincarnated into a District Eleven that looks nothing like the one in my memories.

Now I’m just a plain District Eleven boy. Toss me into a crowd and I’m the most average of the average.

At first, as a reborn guy, I thought I should do something…

Even if I couldn’t copy those countless transmigrator seniors and hustle my way to fame.

But hey, I’ve got a little sister, a house, and parents always busy. Opening a harem should be easy, right?

Then an inborn system shattered every one of my delusions.

It’s a system that forces me to fully conquer ten women before I turn thirty and become an Archmage.

—you think it’s that simple?

Unfortunately, the system comes with a permanently active Opposite-Sex Repulsion Aura.

You heard me right. Not a protagonist halo. Not an idiot halo. A Repulsion Aura for the opposite sex.

Under this aura, every woman in this world hates me. First-meet favorability starts below zero. How do I even describe that scene?

—Every woman looks at you like you’re pure scum, itching to tear you into pieces.

Worst part? If I fail the system’s task before I become an Archmage at thirty, that Opposite-Sex Repulsion Aura flips into a Same-Sex Attraction Aura. Then every guy who sees me gets bent on the spot…

That nightmare is the last thing I want to see.

By the way, starting tomorrow, I begin my new high school life. A real District Eleven high schooler at last.

——————

Over a decade ago—maybe some god yawned by accident, or aliens hauled me off to run experiments.

Either way, Kamidou Chiyo, me, landed in this strange world.

Countries are gone here. Only districts remain. I was born into a regular family in District Eleven.

The moment I was born, I knew something was off. My mother looked at me the way TV stepmoms look at unwanted kids.

Back then, clueless little me almost got thrown to death by my own mother. Dad walked in just in time and saved me. People chalked it up to postpartum depression.

If I’d really been smashed to death… this novel wouldn’t exist.

Later, I slowly realized how wrong women around me acted toward me—even as a baby. Even the nurse sisters who should’ve been gentle were the same.

Rough, cold, blank-faced. Me making it this far is a miracle.

This kept up till I was four or five, when the system suddenly appeared.

I was thrilled at first. Then I learned what the system wanted.

In that instant, ice water drenched me from skin to soul.

The moment it activated, I started seeing a weird heart-shaped panel floating above everyone’s head, with a number on it.

Yep, it’s that legendary ability—an affection meter, like one of Kusuo Saiki–style tricks. And that’s all I’ve got.

No telepathy. No psychokinesis. No x-ray vision. No precognition. No teleport. No far-sight… none of those Superpower perks.

All I can do is see people’s favorability.

In short, I’m just a regular high schooler.

For now. The system says whenever I fully conquer a woman and raise her favorability to 100, I’ll unlock a random Saiki-like Superpower.

Sounds easy, right…

Reality smacked me hard. Every woman I meet starts with negative favorability!

By the meter’s scale, 50 is the line. Above 50 counts as normal friends. Below 50 is basically cold.

Even at 0, it’s just “dislike.”

But under the Repulsion Aura, every woman’s favorability toward me becomes −100.

Holy crap! If 100 means head-over-heels, madly in love…

Then what does −100 mean?!

It means hatred like I killed her father. It means every woman looks at me with man-eating eyes, like I’m trash.

At that level, raising favorability is harder than climbing to the heavens.

She won’t accept any kindness. Forget all those strategy tricks. Everything you do is pointless.

Unless Kami-sama himself possesses me, maybe I’d have a shot.

Even now, I still haven’t raised any woman to 100.

Even my little sister—Kamidou Ruri—whom I’ve cared for since we were kids, is only at 10. That’s “cold and not very familiar.” Probably just because she’s my sister.

Kamidou Ruri and her little brother, Kamidou Hidetomo, are twin siblings. Fourteen. Middle schoolers.

As for Hidetomo, he looks exactly like Ruri.

How do I put this… for a boy to look that… feminine… it’s a miracle.

Because he’s male, my aura doesn’t affect him. While I kept grinding Ruri’s favorability, I accidentally pushed his to 80… the kind of “could be toppled anytime” state.

Don’t get me wrong. I’m not into cross-dressing boys. I’ve just trained myself to ignore the floating meters, or those numbers above everyone’s head would drive me insane.

Plus, the twins look perfectly identical, so I kept mixing up my target. And here we are.

What? You’re saying going after my own sister gets me shipped straight to the incest ward?!

Why the hell should I care? In a world where every woman wants me dead, getting a Superpower would be freaking awesome!!

So, to finish the system’s mission—and to keep from becoming a target chased by countless men—

I have to complete this cursed task before I hit thirty!!!

Otherwise, it’s straight into a BL-game world built by fujoshi…
