So it is a shounen (?) manga where the MC can be considered evil/bad, they are considered monster smth like that since they are using blood and their body to turn it into a weapon, the MC can make it like shotgun and he can also wield fire along with it. PLEASE HELP ME FIND THIS MANGA COZ I MARINATED IT FOR TOO LONG THAT I DID NOT REMEMBER THE TITLE T___T
used to cover the main to describe the passage of time that passes by due to their conflict? I don't feel like they're going to handle it by confrontation, it feels like the author is going to make it subside and make them "casual" when they met again IDK ANYMORE THIS IS FRUSTRATING
