Anime Crossover: In Kamen Rider, I Join the Holy Grail War from the Start

When the Holy Spring runs dry, a fearsome warrior appears like lightning, and darkness swallows the sun.

Beneath the black sun, in an endless wilderness.

A figure wreathed in black flames stands before the corpses of 51 undead creatures, one hand gripping an undead mantis by the throat.

His eyes are filled with despair, fury, helplessness, and hatred.

Underfoot lies a white clown, its body streaming with green blood.

"It's over..." The shadow painfully forced the words from his throat.

Perhaps the so-called path of protection means being ruthless enough to slaughter every enemy.
