how i can see, basically the mc (main character/blonde hair) has been reborn 100 years later by his "king".
In his backstory from what we can see, he had a family, was happy but he had war(?) with a country. With the war, his country is now ded and all the people who lived there died including the mc.
From some flashbacks we can see he adored his family. Mc was maybe a warrior/knight or even personal guard for the king of his hometown(?is it a town?) considering his movements of killing demons. Right now we don't know that much, just that he wants to go back to his hometown.
In the present, 100 years later, he been reborn as human(?maybe demon, inhuman?). He looks like a demon because of his aura(?) and gets mistaking as a demon. Because of that he gets pierced on his head by a sword. He then goes to a merchant(?) to get some changes in his body (ya know like how theres a dead body? Maybe they think they can make changes to his body to make him a war device machine). Then he wakes up being and he becomes friends with the merchant ya.
All we know is, he is emotionless, cant feel any pain, maybe because of his reborn?? and hope you understand ٩(๑❛ᴗ❛๑)۶
