The Devil's Bible

No female lead, dark style, boss flow, non-human protagonist.

Original otherworldly Western fantasy setting.

"Why? Why can you break the contract?!!"

Facing the question of the unwilling, the demon unfurled the contract.

The contract was magnified, and he saw clearly the 'paper' that constituted it.

It was a network of extremely fine threads, woven together in a special pattern to form the characters that carried the information.

[Supplementary Clause 1: ...]

[Supplementary Clause 2: ...]

[Final Supplementary Clause: All final interpretation rights of this contract belong to the demon Naimus.]

Naimus, who had crossed into another world and become a demon, awaited the once-in-a-lifetime perfect wave. Thus, having obtained a part of the divine authority of commandments, he step by step usurped the divine throne and composed his own Bible.
