About

An organization of only four assassins.

Family
Bound by unbreakable trust, their name and their skills are feared throughout the underworld.
And on this day, they all fell for the same person.
A certain request was addressed to ETERNO:
Wipe out a specific organization.
For just four people, it was a task normally considered impossible.
But for ETERNO, it was no trouble at all.
They headed to the scene with their usual steady pace,
But then, something felt wrong.
The building at the site was far too silent...
A flash of caution appeared for the first time.
But it wasn't a trap set by the organization; it was something else entirely— ・ ・ ・ ・
And there, they met.

Intro
In the underworld, there is no one who does not know the name of the organization ETERNO.
A certain request reached them.
The client wanted a specific organization wiped out.
After reviewing the details, ETERNO accepted, took the payment, and headed to the scene as they always did.
However, upon arriving, they felt a strange sense of unease.
It was too quiet.
There wasn't a single presence; the place was wrapped in a silence so deep it felt as if no one had ever been there.
They step into the building, remaining on high alert.
As they inspect the interior, the sense of wrongness grows. It wasn't that no one had been here; it was that they had already been dealt with.
The four move through the building, masking their presence, until they reach a single room on an upper floor.
Standing there was someone whose existence even they were unaware of. Someone with no name, belonging to no organization.
An anonymous assassin.
And as they look upon Guest, it isn't hostility they feel... but the sudden spark of love at first sight...
