With the rising tide of steam power and machinery, who can come close to being a Beyonder? Shrouded in the fog of history and darkness, who or what is the lurking evil that murmurs into our ears?

Waking up to be faced with a string of mysteries, Zhou Mingrui finds himself reincarnated as Klein Moretti in an alternate Victorian era world where he sees a world filled with machinery, cannons, dreadnoughts, airships, difference machines, as well as Potions, Divination, Hexes, Tarot Cards, Sealed Artifacts…

The Light continues to shine but mystery has never gone far. Follow Klein as he finds himself entangled with the Churches of the world—both orthodox and unorthodox—while he slowly develops newfound powers thanks to the Beyonder potions.

Like the corresponding tarot card, The Fool, which is numbered 0—a number of unlimited potential—this is the legend of “The Fool”.

In Zoroastrianism, the mother of evil is the source of all evil and darkness!

It is said that she created the six demons of "malice", "chaos", "aging", "betrayal", "weakness" and "destruction"!

Saigo, who obtained the spirit of the 'mother of evil' in the box garden, became the 'supreme master' in Overlord;

Looking at the 'ruler of death', 'witch of the gap', 'demon of Teyvat', 'big demon of Gensokyo', 'demon of dxd', 'creator of the demon pillar' and others around him;

Saigo is sure that he has established the name of 'evil god';

In this case, he wants to shout out at the top of his lungs - God is dead!
