I, Satoko Umeki (28), was summoned to another world.

Someone who seemed to be a prince was there too, but along with everyone else, he only spoke to the other summoner, ignoring me.

As I was wondering, 'What am I supposed to do...?', the person who seemed to be a prince noticed me and scoffed at me.

"You extra old hag, get lost!"

Along with those abusive words, I was kicked. And I snapped.

Suddenly, a scream echoed.

The prince-like person suddenly aged.

Then I realized.

Huh? Me... I haven't become an old lady, have I!?

Wait a minute! I'm 28 years old!?

It's a world where magic exists, and there's a mysterious law that aging temporarily stops at the age when one's magical power is most abundant.

Because the summoning magic circle contained a curse that summons people 'in the form of the age where their power—specifically, magical power—is most abundant,' I was summoned as an old lady.

While ordinary humans' power weakens as they age, Satoko is the opposite. She was a cheat, her power growing stronger the older she got—but she herself didn't know.

Because the country that summoned her was terrible, she promptly departed (after thoroughly collecting a nuisance fee).

To return to her original form, and to return to her original world.

An old lady in appearance, with an unpleasant personality, the strongest protagonist embarks on a carefree journey.

※Written on a whim, the length of each chapter varies.

※The protagonist generally does not have a good personality. Her language is also not very polite. (This is important)

※I'd like her to experience romance someday, but the protagonist thinks things like 'Huh? Mature woman fetish? Or rather, old hag specialist?!?' so I feel like it might not progress.
