Looking for a anime I watched like 6 years ago
I remember seeing it on Netflix and it pissed me off so bad that I still feel that anger, but I just can't find it. By what I remember it was about this depressed black haired guy living in a rather rundown secluded wooden house, he was the son of a blacksmith or something? He was friends with this girl who was basically his only friend, they may have had feelings for each other I don't remember
I remember him having a dark sword that was seemingly corrupting his mind or whatever, he ends up jumping off a building and landing in front of his bestie, then the series suddenly shifts focus to this rich blond kid that immediately becomes friends with the girl and keeps the sword
EDIT: found it! Sword Gai, now I can go back to hating it properly
