Till (てぃる)

I am Gilbert Orto, the second son of Viscount Orto, a member of an aristocratic family in a corner of the Kingdom of Franmecia. I had grown up normally, but when I turned 4 years old, I realized, "This world is the same game I played many times before I was reincarnated, 'Eugene's Miracle'!" Moreover, there was no demon king. I wonder if it's the world of a sequel after clearing it? That game had a guaranteed loss event, and it was terrible. This current situation that only I know is not the time to live a leisurely life, and I can't let my guard down. We have to acquire knowledge and strength from the age of 4 to survive...!!

The heroes, summoned to a different world by the goddess to defeat the Demon Lord, returned home after sacrificing much. However, the alchemist Koudou, who was supposed to return with them, was left behind in the other world because he was in the midst of alchemical concoctions when the goddess's power repelled him during the summoning. How will he survive in this abandoned fantasy world? The production fantasy manga begins!
