How will the journey of a man after he's received a 'mysterious' gift would be?

This is the story of a man going with his changed life amidst the ever-changing and chaotic world, and how he would establish himself in the new world he's dived into.

This is all just a fanfiction, with no actual relation to real world. The credit for characters of anime worlds and their setting are going to their original authors.

This may be my own dream, or it is someone else's dream who wishes to tell their tale through my hand.

Thank you for your understanding.

Ps: I also write this in Webnovel.
