In front of my eyes, Iona, who had just eaten my sweaty panties, which had turned into a high-level magic catalyst, was now undergoing a sudden evolution.
No, this wasn't a sudden evolution...
That's was a stealth slime evolution that supposed to be happened, after giving Iona my sweaty panties.
I've been thinking about this and guessing that Iona's evolution would happen after she ate my sweaty panties.
Iona's magic core begins to enlarge and is filled with holy magic originating from the Goddess of Destruction, which causes Iona to evolve into a stealth slime that is different from Aiko and Sirius.
The intensity of the holy magic absorbed into my panties seems to have created a new evolutionary path for a stealth slime, especially for Iona.
