Learning the Sword in a Western Fantasy World

The Western fantasy world has demons, beastmen, elves, all kinds of magic, and powerful swordsmen. But none of that matters to Ronoxia, who is struggling to survive in a deep forest, because she is the only human there. Everyone else is a magical beast. When Ronoxia opens her eyes, she thinks she's become a white tiger cub, because she's nursing from a tiger mother. But once her memories return, Ronoxia looks at her hair, which is almost the same color as a white tiger's, and thinks about how she's behaved like a beast for the past few years. She can't bear to look. Oh well, she's the only one here anyway. Except an elf is stroking her head. Everyone knows that Ronoxia, the world's strongest person, is like a well-behaved cat in front of her beloved, Fuladinis. Theme: The strong need a resilient heart.
