I feel like I know what youre talking about but I need more details
All i can say is they wear this kind of Jujutsu kaisen jacket for the main characters, like its their uniform. I forgot what the mc has done but only people with the worst sin was the ones who were being punished to be the angles of death. However after the Introduction the story shift into some kind of flashback of a girl the mc knews since he was a kid and kinda idolize her somehow and i think she was kinda reckless of her life by chasing adrenaline by doing something dangerous? Thats where i stopped reading unfortunately. I'm not even sure if this was correct its probably two different manhwa and my whacky memmory cus i probably read it like seven years ago or something.
Reading this just awaken my old ass manga (?) ive read in highschool. I cant remember the name but similar to this it has black n white style and almost western-ish art style where the mc (male) was dead then got 'transformed' into some short of angle of death where his job was to collect soul, apparently to redeem his own sins during his life time which he need to work for the gods now. It doesnt look magical, but strangely look modern with jacket and train in the sky as their HQ. Im losing my mind cus ive been searching with keywords and nothing came up.
