I don't think this is double genderswap.

I think the childhood friend was saying goodbye to MC because she was returning to be a hero in her original world and would never see him again.

So the description should look more like this.

The MC's childhood friend (♀) suddenly shows up to say goodbye to the MC (♂) after vanishing for weeks.
Childhood friend (♀) gets attacked by a living weapon (♀), but the MC (♂) gets in the way and dies.
The MC (♂) is then reincarnated in another world as the living weapon (♂->♀) that just killed him created by the demon lord, while his childhood friend (♀) suddenly shows up as a hero vowing to fight the demons.

The description isn't that bad.

But i really got into the story, watched the other chapter in raw and got really curious of why that side is evil, and if the MC will stay on that side?
Can't wait for the next translated chapters.

Got so into it, that i even used google lens on cellphone to translate the dialogue, but most of the times it didn't make sense :(

@tuturuu
MC boy dies and reincarnates to a different world of as a different looking girl. Friend in previous world that is a girl is somehow in this reincarnate world. Friend is instead now a boy (looks the same) that sees MC as an enemy (doesn't recognize MC). MC recognizes friend. MC is on the demon lord side. Girl is on the hero side.

I'm not sure if this is clearer or not. Haha.

I did not understand the description until I read the manga. And then I was glad the description was there since it was less confusing combining the two. xD

What the fuck is that description

This is just my opinion.
The plot is moving too fast. I would prefer if they take it slow and tell a proper story. In chapter 1 they could have created two chapters instead of one chapter, for example. Chapter 1 could have focus on the main character dying and being reborn into the unknown body then trying to know why is he in that body, then chapter 2 could have focus on the hero then realizing that the hero is someone he knows. But this is just my taste in story telling, I know many people would prefer a story that is told fast and finishing each major plot points in a single chapter. And also remember the first sentence I said.
This is just my opinion.

@tuturuu tbh even the Tl;DR gives a good TL;DR of the TL;DR : Reincarnation + Isekai + Double(?) Genderswap.

This story is overly complicated and ridiculous and I like it that way. Lookin' forward to more.

I'll post his here for people who dont understand chapter 1. Spoiler Also lots of people tend to vote 1's for gender-bender mangas even when the story is pretty original and promising 🤔

Saw the raws for this one awhile ago. Glad it's getting translated.

I like it more please!

Hmmm I guess im down lol

someone give me a tl;dr on the tl;dr

Wow, lots of people are giving this 1s

just reading the description was a ride

Wait is the childhood friend turned hero gender swapped to, or just really flat?

YES YES YES YES YES YES YES YES YES YES YES YES YES YES YES YES YES YES YES YES YES YES YES YES YES

Looks interesting.

@Lohengrin : Saw the RAW before, the translator got that bit wrong
Spoiler

@Lohengrin either that or he became the hero for the demons, I guess that's one way to put it...
