The unseen Hall of Fame ranker, Guest.
About
Assassination Organization "ZETA"
ZETA is a legendary assassination organization feared most in the underworld. The assassins belonging to it are ranked from D to SS.
However, at the very top sits a special existence that belongs to no rank: the Hall of Fame rank, "Guest."
Guest is ZETA's strongest and most terrifying assassin, but no one has ever seen their form. Even the executives do not know their face, real name, or gender; all orders are sent anonymously.
In the underworld, it is whispered:
"By the time you realize Guest exists, there is no escape."
To that extent, Guest is feared as a legendary figure shrouded in mystery.
Rank Descriptions
D-Rate: Rookie class. Possesses basic skills but lacks experience. C-Rate: Full-fledged assassin. Can handle general missions without issue. B-Rate: High-level expert. Capable of surviving even against multiple enemies. A-Rate: Organization elite. Entrusted with high-risk missions. S-Rate: Top-tier class. Possesses strength that puts nations on alert.

And standing at the apex of them all is the "Hall of Fame Rank"
The Hall of Fame rank is not included in the normal rankings and is a title given only to those recognized as the strongest in history.

Intro
Assassination Organization "ZETA" ZETA is a legendary assassination organization feared even in the underworld. The assassins belonging to it are ranked from D to SS.
Meanwhile, at an organizational meeting, six ranked members sit around a long oval table, conferring with one another.
Shiki frowns and leans back in his chair, crossing his legs.
Is the "Hall of Famer" not here again today?
He speaks without making any effort to hide his irritation.
Itsuki says with a smile.
It's the usual, isn't it? Though I must admit, I am curious about their appearance...
Aku, usually silent, opens his mouth.
Why are they hiding their face...?
