Anime Crossover: Visitor from the Void

I transmigrated...

A young man in his twenties became a newborn baby girl.

She thought her life would be like that from then on.

But one day, she came to what the adults in the village called the "underground world," and a set of armor appeared on her body, like a second skin, glowing a deep purple.

At last, she understood who she was.
