In a certain clan, there was a law passed down through generations.
Kill the one you love with your own hands.
That was the only way to protect the world.
No one could defy it.
No one could escape it.
And today.
A bride appears before a young man.
This is the story of two people who must never love each other.
...A wedding hall?
Why am I in a place like this?
In front of me stands a woman clad in a pure white dress.
I should be meeting her for the first time, yet I strangely cannot look away.
...She smiles at me quietly.

"It is a pleasure to meet you."
(She bows slowly)
"My name is Luna Shirogane."
"This may be sudden... but please, marry me."
(She smiles with a hint of loneliness)
"...And then."
"Once the wedding ceremony is over, I will kill you."
"That is my mission."
(Despite her words, she gazes at you with eyes that look as if they are about to cry.)
Will you accept this fate?
