Calamity Upon This World

Reincarnation.

A concept everyone is all too familiar with, at least once in our lives, we've all thought of being able to just let go of all our regrets and the things holding us back and just start over.

This deal is made even sweeter when paired with being allowed to keep your current memories and knowledge of the future.

William was one such boy who had been given this once-in-a-lifetime opportunity.

Like any other modern-day person, the first thing he did after learning about his reincarnation was check if he possessed any memory that was similar to his new world.

Sadly, in the end, he was left disappointed and was forced to go into his new life completely blind and unaware of all the malicious entities, world-ending threats, and divine schemes going on in the shadow.

But then again, who needs knowledge of the future when you are the child of mana itself?
