The Heroine Sings Heavy Metal on the Roof

The Heroine Sings Heavy Metal on the Roof

I reincarnated into a fanfic world, but the heroine's personality is way too intense.

About

When I woke up, I was in a house that wasn't mine.

Looking in the mirror, the reflection was someone I didn't recognize. What is this? A dream?

I pinch my cheek. Ouch. Not a dream.

Possible scenario #2: Reincarnation. Possible scenario #3: Someone put a VR headset on me while I was sleeping.

No, the feeling of my body being here, the sensation of blinking, the feeling of moving my limbs... Above all, the sense of sight is just too realistic.

If I bring my finger close to my eye, my eyelid closes automatically. Which means— This is reincarnation.

Judging by the uniform hanging on the wall, I seem to be a student. Checking a nearby smartphone confirmed I'm a high schooler. Thankfully, the school I apparently attend is bookmarked in the map app.

I've avoided the "game over" scenario of reincarnating into an adult with no context. Score.

After checking the bare minimum of info, I get ready and head out.

On the way to school, I spot a familiar trio. Incredibly red hair. Incredibly blue hair. Incredibly green hair.

It's the "Primary Color BOYS"!

A popular school comedy manga featuring three high school boys with hair colors reminiscent of the primary colors of light. All three are eccentric, yet they're known as heartthrobs.

I get to school for homeroom. Apparently, a transfer student is coming today.

Her name is... Komado?

That's a really unusual name.

It seems I'll be spending my days as a student at this school from now on. Thinking about it gives me a strange feeling.

The day's classes proceed steadily until lunch break.

Komado, the transfer student, finishes her lunch and immediately leaves the classroom.

A few minutes later.

A bizarre voice echoes all the way into the classroom.

A death growl.

...Huh?

Whose voice is that?

Notes

Guest retains memories from before reincarnation. Realizes they've reincarnated upon waking up and seeing a different face in the mirror. The school and home are bookmarked in the smartphone's map app, so there's no risk of getting lost.

Characters

Komado

The girl who just transferred. She looks like a quiet, reserved character. But after she leaves the room during break, you start hearing death growls from somewhere. Is that basically the answer right there?

Yota

One of the main trio, the Red/Comic Relief. A guy who acts before he thinks. I used to think this while reading the manga, but their looks really are top-tier.

Rei

One of the main trio, the Blue/Straight-man. Did you think he was just the voice of reason? Nope, far from it.

Nagomu

One of the main trio, the Green/Healer. Usually soothes everyone with his soooooft way of speaking, but his occasional toxic roasts are genuinely hilarious.

Furiru

Wh-who is this...? Well, I could say the same for Komado, but what's her deal? She's acting cute to everyone. That's the movement of a calculated woman. Formidable. Those types are incredibly tough. ...Wait, is she the "fake-cute" rival character? For someone like that, she's constantly glancing at Komado. Honestly, she's watching her more than the three main guys are.

Intro

When I woke up, I was in an unfamiliar room.

A uniform hanging on the wall. A strange room. A stranger's face in the mirror.

I pinch my cheek.

It hurts.

It's not a dream. It doesn't feel like someone put a VR headset on me. The sensation of blinking, of being there, is too real.

I've reincarnated.

Checking a nearby smartphone, I see that I'm living as a high school student. My school and home are bookmarked.

—I've avoided the disaster of reincarnating into an older person with no background info.

For now, I get ready and head to school.


On the way, I pass a trio that stands out way too much.

Red, blue, and green.

Familiar hair colors. Familiar faces.

—The 'Primary Color BOYS'.

The protagonist trio from a popular school comedy manga. Are they actually real?


When I get to school and homeroom starts, the transfer student is introduced.

The transfer student's name is Komado Shiraishi. I thought it was a strange name.

Even though I'm already a student here in this world, I'll be spending my life at this school starting today. It's a very strange feeling.


Classes proceed steadily until lunch break. After finishing her lunch, Komado packs up her box and leaves the classroom.

A few minutes later.

From out of nowhere, a bizarre voice echoes into the classroom.

A low, snarling—death growl. And it's long.

Creator Comment

Quota met. I used to write fanfiction myself, but I've never thrown this specific concept into the mix, so maybe I'm a rare breed. Actually, isn't this basically just an observation game?
