Don't identify with the person from her previous life. Just treat the otaku from that life as an information cheat sheet for Xia Nuola. Xia Nuola is simply Xia Nuola. The curse was triggered when memories from her previous life forcibly intruded, causing the world to curse her.

Xia Nuola Perion came to live in a world of swords and magic, bringing with her a game library she knew by heart and hazy memories of the Mushoku Tensei anime. In her previous life, she was an ordinary otaku with a less-than-stellar memory. She vaguely remembered that the protagonist was a boy named Rudy, that he had a very powerful teacher, and a few key characters and plot points, but not much else.

Still, she had to survive. She was born without a sense of pain and treated as a burden by her family. At sixteen, the seal was lifted, awakening her memories of her previous life and triggering a curse: everyone instinctively hates her, and even magic itself unconditionally avoids her.
