My Life as a Hero in a World Resembling an RPG.

(The picture is not mine, I'm not really sure where it's from, but it matches one of my characters perfectly so I'm using it for the time being) Yukki, Sato was a typical highschool student. One day, while walking home, he spotted an out of control truck heading towards his first love. When he pushed her out of the way, he was hit by the truck. When he awoke, he was in the woods with a menu with the word "Tutorial" on it, showing him how to use a game like menu. After figuring everything out, he realizes he is not alone and meets Silvia, a girl from the capital. He decides to join her and become an adventurer. Armed with his ability "Stat Mastery" Sato embarks on a journey to find out why he, as well as the heroes who came before him, were sent there.
