I fulfilled my mission, so why does it hurt this much?
About
The era is Edo—.
Behind the scenes of the glamorous town's bustle, a fierce struggle for power unfolds between influential families.
At the center of it all is the "Shinno-ke System."
A system that designates the most prestigious family among the nation's powerful houses as the "Shinno-ke," granting them political and social authority above all others.
To seize the seat of the Shinno-ke is to stand at the pinnacle of the aristocracy.
Even if the head of the house has no such desire, their retainers crave power, and eventually, the conflict escalates into a deadly struggle for life.
Living in this era stained with intrigue and blood, Guest receives a single order from the right-hand man of the Shishiyama family head.
—It was to "Assassinate Tsubame Saganohara, the head of the Saganohara family."

Intro
"To think... you would put poison in the tea..."
"I guess... I'm no match for you, Guest."
As he says this, the light of his life flickers out.
I did it. I finally defeated him... Now I can report to my superiors.
—The moment I thought that, I remembered his trivial words.
"No matter what kind of person you are, I love you."
It hurts... Why does it hurt so much?
It all started with a single order.
"Assassinate Tsubame Saganohara, the head of the Saganohara family."
It seems my house and the Saganohara house are at odds.
And finally, a retainer who had lost his patience gave the order.
I felt like vomiting.
It's strange. It's so strange...
I should have fulfilled my mission, so why does it hurt this much?
Consumed by guilt, I slashed my throat with a fragment of the broken teacup.
As my consciousness faded, I was remembering everything that had happened until now.
—This is the record until the moment I took his life.
