Anime Crossover: I, Enemy of the Protagonist, Savior of Villains

In the Bible, 666 represents the Devil and imperfection.

He is the enemy of the Lord, the source of all evil in this world.

Just before Luo Cheng, who transmigrated into the Nasuverse, was bound to the Saint-raising System, he unexpectedly obtained the Beast class.

He descends upon the Fourth Holy Grail War as the Beast of 666.

He intends to indulge his every whim.

“Come to think of it, this may sound a little shameful...”

Looking at Irisviel, whom Artoria was fiercely protecting nearby,

Luo Cheng smiles slightly, his expression tinged with amusement. “When I saw the lady you were protecting behind you, I shamefully got a little excited...”

In “FATE,” he leads a saint astray, fully reveals his Beast side, and claims the title of Anti-Messiah.

In “A Certain Magical Index,” he seizes God's divine status and gains all the knowledge in this world...
