Manga and the 1997 anime
This goes so fucking hard. My favorite thing about Berserk is how the creator Kentaro Miura originally made it to just bring his coolest teenage boy, ultra violent, badass fantasies to life but through the story of Guts and how this character evolves we also see Miura maturing. It's a process that many young boys have got to go through and it's uncomfortable and scary and that's what Berserk is. It's horrifying and beautiful and sometimes funny and mostly heartbreaking.
*As a warning, Berserk is incredibly graphic*
