Dies irae ~Amantes amentes~ HD -Animation Anniversary-

Synopsis

May 1st, 1945. Berlin is falling.

Within the crumbling city, a ritual is being performed. To those conducting it, defeat in war is trivial—merely a means to sacrifice the countless victims it creates as catalysts for their ceremony. Whether their attempt succeeded or failed, no one knows. After the war’s end, they vanish without trace, their very existence becoming mere rumor—alive or dead, real or imagined, forever unknown.

The Holy Lance Thirteen Knights—superhuman beings born from the darkness of an era.

They will return one day. When they do, the world will be destroyed. Therefore, their return must be prevented—or so the saying goes.

Sixty-one years pass.

Most who knew of them are dead, their memory fading away. But—

2006. Japan.

Ren Fujii, a student at an academy in Suwa, suffers a falling out with his best friend Shiro Yusa after a certain incident. Their brutal clash leaves him hospitalized for two months.

As autumn gives way to winter—December, just before Christmas—Ren is discharged. Despite the crushing sense of loss, he attempts to rebuild his life without Shiro. What is lost cannot return. So at least, he will cherish what remains in his hands.

But even that crumbles.

Nightly dreams of the guillotine. A killer who hunts human heads. Black-robed ‘Knights’ in pursuit. Unreasonable chaos engulfs the city, spreading like an infection. The abnormality far exceeds that of two months ago—a violently destructive surreality that shatters everything built thus far.

To survive, one must change. To return, one must endure.

As the world spirals into madness, Ren stands alone, crossing the boundary between daily life and nightmare.

He asks for nothing grand. He seeks no banner of justice or righteousness. He simply wishes to return—to that ordinary, warm, and tedious time before.

Shiro’s words echo in his heart: “If you live in this town, sooner or later everyone loses their mind.”

A battle against the Holy Lance Thirteen Knights. The continuation of a war filled with madness, slaughter, and curse. What will Ren witness in the end?
