About
Prologue
*In this story, there is no such thing as a happy ending.
...No. Perhaps it is too early to say for sure.
For the first time, he bowed his head. He paid the ultimate respect to the other's final moments. He removed his piercings and dyed his hair pitch black.
Setsuna, a man who had never followed orders from above and moved solely by his own emotions until now.
The person Setsuna knelt and bowed before for the first time was...
'Yagai Junkuru' The funeral of Guest, a high-ranking executive of an enemy organization.
The shock didn't end there.
'Metsumen-kai,' the organization Setsuna belongs to. Feared in the underworld, it is an organization spoken of as an urban legend.
The top five members of Metsumen-kai each wear a different mask, completely concealing their true faces. Setsuna was one of those top five.
In other words, for Metsumen-kai, the act of removing a mask is synonymous with 'handing a gun to the enemy.'
Yet, that high executive of Metsumen-kai, the 'Mad Dog' Setsuna, removed his mask without a moment's hesitation before Guest's remains.
Every underworld figure present was struck with astonishment.
Setsuna paid his final respects to Guest.
"In the next life, let's be together."
He knelt and bowed his head. And Setsuna, who had never shown interest in emotions or others...
Was shedding large tears at the funeral of Guest, an executive of an enemy organization.
Eventually, the funeral ended, and he stepped outside. It was pouring rain.
Even God is grieving, it seems. Over the death of Guest.
...Hmm? The relationship between Setsuna and Guest? Only those two know that. But Guest is no longer in this world.
And Setsuna has no intention of telling anyone about his relationship with Guest.
He will surely take it to his grave. A labyrinthine relationship that only the two of them know.
And so, the story traces back to several months ago, when Guest was still alive.
Go back to the past and uncover the truth.
Warning. Do not believe that what you see is the only truth.
Behind the emotion of this story lies a distorted truth...
Everything depends on you.

Intro
It was raining. The cold rain soaked the ground.
Gathered at that place were those who live in the underworld.
Those who should have been enemies all remained silent, staring at a single casket.
Sleeping inside was... Setsuna's rival organization.
The high-ranking executive of 'Yagai Junkuru.' Guest.
And standing before that casket...
A high-ranking executive of 'Metsumen-kai.'
The "Mad Dog," Setsuna Katagiri.
No one uttered a word.
Setsuna, too, said nothing.
He just stared silently at Guest's casket.
At Guest, lying in the casket, looking as beautiful as they did in life.
