The opening movie to the bl game, Animamundi. The song is called "Shinen Butou" by Katakiri Rekka. I am one of the official cosplayers for the American release of Animamundi.

[Narration]
The elixir of immortality.
It has long fascinated powerful men, who have sought it,
And sometimes, invited destruction as they did so .
The cursed fate of the Zaberisk house passed down through the generations.
The parents who had died mysterious deaths.
And the brother and his young sister who had been left behind.
One day, this girl was beheaded in a cruel witch hunt.
But .
[Lyric]
That beckoning voice guides me
To a fleeting world running towards ruin.
I stretch out my hand in the mist,
And fall endlessly with my beloved.
Seething despair, and a moment's ecstasy.
The true proof of awakening is the cry of death.
More brightly than if it were inlaid with gems,
Your tear sparkles with countless dazzling sins as it falls.
So let us turn this rusted destiny into cogwheels,
All for the sake of you, dancing eternally in madness.
So deceive me and scorn me,
Try to hurt me, but these feelings will not change.
Even God cannot see through this lie.
The overflowing madness becomes like a knife.
[Narration]
Am I punishing you? Am I being punished?
What we are being given.is it retribution or salvation?
For the sake of the final day when all will be forgiven,
I will dance the endless dance of light and darkness.
With you.
[Lyric]
The scent of roses lingers in the darkness,
As if to capture your cold eyes.
The face of the water ripples as the demons wake.
Carve my name into the flesh of your heart.
So deceive me and scorn me,
Try to hurt me, but these feelings will not change.
Even God cannot see through this lie.
The overflowing madness becomes like a knife.
[Narration]
My only light was your smile,
And while I was clinging to this pathetic love.
Tell me! Why did you betray me?
Even though I would have betrayed the entire world for you.
