After My Transformation, I Became a Superpowered Princess

I used to be the son of a powerful underworld boss…
But after dying, I woke up in a completely different body—

A holy maiden. A princess. A girl.

Fine. I can accept the gender change.
But why am I just a useless “vase” saintess?!

Where’s my protagonist cheat?! My golden finger?!

Collect the Twelve Zodiac Spirits?
Gather the Twelve Constellations?
Conquer all ability users across the world?!

…Are you kidding me?!

Watch as a former mafia heir, now a transformed princess with supernatural powers, rises from being underestimated to dominating the world of abilities!
