Fairy Tail: I Stole the Ryujin Jakka in My Sleepwalking - Chapter 227: FTRJ -

In this world, human are in peril. 72 Obelisks suddenly appeared out of nowhere, infecting the world with Monsters. Amongst this chaos, people look for hope.

A man named Basil Pacifer is the humanity's hope. He is the strongest Mage alive at that point. Sadly, he believes in no man, and he always moves alone.

...

Basil observes the unfolding scene bitterly. He is aware of his impending doom, however he has no grudge. He has lived long enough to achieve things people can only dream about.

Looking back to his past, he realized his life is nothing more than a sad story.

Closing his eyes, he accepted his end — or so he thought.

...

”Look at me! What do you see?“

”Regrets.“

”Don't you want to undo it?“

”Tell me what the offer is.“

Thus, Basil Pacifer returned to the past, being his younger self once again. Of course, he returned back with something.

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

Legend? Created six demons of “Malicious”, “Chaos”, “Aging”, “Defection”, “Weakness”, and “Destruction”!

Saigo, who obtained the spirit of the “Mother of Evil Gods” in Hakoten, became the “Supreme Supreme” in the overlord;

Look at the ‘ruler of death’, ‘Void Witch’, ‘Tivat’s Demon God’, ‘The Great Demon of Gensokyo’, ‘Dxd’s Demon’, ‘Creator of Demon God Pillar’ and others;

Xixiang is convinced that he has lived up to the name of the “Evil God”;

That being the case, he would shout out the phrase – God is dead!
