KYOUSEI TEKI NI SLOW LIFE!?

Description

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 grew 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 is no demon lord, so I wonder if it's a post-clearance/sequel world...
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...!!
