Doubt Him, Understand Him, Become the Overlord

At first, Bai Hen questions the Holy Lord, one of the Eight Great Demons.

Then, Bai Hen clears away every obstacle to the Holy Lord's rule.

Finally, he says, “Holy Lord, your power is impressive, but now it belongs to me. You old fossil should just go to hell, and let this be my era!”

Bai Hen: “Would you be my shrine maiden, Kikyo?”

Kikyo: “Then may I ask if you would be my god?”

The advancing Holy Lord: “I finally caught you, my dear chancellor!”

Bai Hen: “Holy Lord, watch closely. This is how you use the Book of Ages!

In the war between dragons and hybrids, there are no innocents. In a war like this, you have to fight to survive!

Chu Zihang: “Once a Dragon King, always a Dragon King! Transform!”

Bai Hen: “I have infinite energy and the power to grant wishes. My very nature is darkness, so of course I can be the Holy Grail!”

“Now my Holy Grail War begins. Heroic Spirits, show me everything you've got and entertain me!”
