Lone

Synopsis

Born without magic in a world full of witches, Lone is determined to claw her way to the top of wizarding school if it kills her — and it just well might! After a deal with the devil improves her magical aptitude and leaves her with a parasitic demon lord stuck to her forehead, Lone's dream is finally within reach. Now she just has to survive long enough to graduate high school... and help Lord Beelxaroth retake his rightful throne as King of Hell so that he'll finally get out of her hair. (Source: Webtoon)
