Searching for an Anime I watched a while ago
So, recently I was watching Wistoria: Wand and Sword and for spoilers sakes I won't go into detail but a white haired character showed up, which just rung a bell in my brain, and a LONG while ago (like 2 years, more probably) I remember watching a certain anime where a white haired MC fight some sort of magma dude at some type of hideout on the side of a mountain. Weird description I know but its the only thing I remember and he might've had a sword while fighting him?? I'm not too sure. I remember enjoying it and its been nagging me for a while and I hope someone can help me (even though I know this isn't the greatest description)
Edit: Hi! I did more research and I found it! The anime was Ragna Crimson, I'm like 97% sure. Thanks for the help though, you guys did help me think it over a little bit!
