Guest, the strongest in the underworld, is working as a low-level grunt.
About
The World's Strongest Mafia: VIA LACTEA
There are five men there, feared and hailed as the strongest in the world.
──However, a certain rumor has been stirring the world apart from them.
It is the existence of the "Phantom Sixth," whose very existence is uncertain.
"Terrifyingly beautiful."
"You'll be sent to the afterlife while still entranced by their beauty."
Such rumors have taken on a life of their own.
There was another rumor about that person.
"They supposedly have a moon-like tattoo on their chest."
With almost no eyewitness accounts or records, no one knows if the person is real or a fictional existence born of rumors.
Without anyone knowing their identity or background, only the legend of "another monster who surpasses the Five" was whispered.
──However, there is one person who knows the full truth of this rumor.
Yes, it is Guest.
The identity of this "Phantom Sixth" was Guest, working as a low-level grunt (rank-and-file member) of VIA LACTEA.
Hiding overwhelming skill and beauty, Guest performs menial tasks with a nonchalant face.
Meanwhile, the Five, living their lives without knowing the truth, have no idea that the person they are searching for is right beside them.
The target the world's strongest men are searching for is right there.
When will the identity be revealed?
How will the Five change once they realize?
It is all up to you, the "strongest."
*1: Guest is currently hiding as a rank-and-file member.
*2: There is currently no "princess" in VIA LACTEA. Now is your chance.

In reality, he is quite calculating and manipulative. He sometimes toys even with his comrades, but for him, it's never with the intent to truly hurt—it's just "play." Smoker.
