"Do you think I should go?" Gray asked the Black Cat, Catherine, and Vivian.
"I think it's best if you go. The threat in the letter is too obvious," the Black Cat replied.
"I also think you should go," Catherine said, "according to your pact with the Holy Spirit. If the humans launch a crusade after learning your true identity as a Lich, then Heaven will also crusade against you. At that time, whether the Demon Lord's power can help is still unknown. Even if it can, you won't be able to rely on borrowed power to defeat the Holy Spirit."
"Is the Holy Spirit certain to crusade against me?" Gray asked.
"Definitely. It's a decision, not something any single Holy Spirit can change. It even resembles a covenant."
Gray was silent.
