I need help finding a specific 2010 ~ 2015 Anime
I am in bed and randomly got smashed in the head with vague memories of an anime I watched as a kid and was momentarily obsessed with but for some reason the name and general plot of the anime eludes me. I watched it maybe 12 years ago on Netflix. All I can remember is the protagonist had long black hair usually in a pony tail with a red robe he usually had around his waist and a magical sword. I can’t remember fully but I have the feeling the character had amnesia but was chosen by this sword to fight the antagonist who was a big burly man(possibly related to protagonist since in my head they look very similar) who also has black hair in a ponytail but a goatee. It takes place in a feudal like world of course with Japanese influence. I think I also remember a sister to the protagonist but I’m really unsure. I remember the anime having a generic name like “hero quest” or “legendary” something. But looking up the names I thought it was got me no where. But I’m struggling to sleep until I can find this anime so I decided to ask Reddit for something for the first time in my life. I’m hoping there’s one goober out here that watches this anime and it’s their favorite so they can realize exactly what I’m talking about cus that would be lit but here’s to hoping I find it before I pass out or end up searching until the sun rises. If I remember anymore detail I’ll try to add in the comments and maybe if you guys have any questions about it I can try to answer to the best of my ability to answer but know I’m likely warping my own memory.
