Shakugan no Shana, maybe?
Any dragons? Lol. I’m sorry it just reminded me so much of yona of the dawn
Loved that anime, but I have another one. Maybe Kaza no Stigma?
Yup, sorrry forgot the 'e'. The girl has red hair and fire, with a love interest that uses wind. The author died before finishing it though ╥﹏╥. Though I think in Shakugan no Shana, Shana has black hair only until she uses her sword.
I want to watch again this anime but can't remember the title
all i could remember was a red haired girl with sword and something about souls. . .i watch this in highschool, ...
