The Heroine Practices Immortality with an Umbrella, Sword, Piano, Flute, and Fan. the Heroine Wears a Red Dress.

Traveling from the end of the world to an immortal, she has a space bracelet, a bell on her ankle, a red skirt, mutated thunder or ice spirit roots, or ethereal roots, has superpowers, and can fly with a sword (I mentioned that one a lot, but if only one of them matches, I can recommend this one)
