Eiji, a depraved, thirtyish NEET with a predilection for young girls, whose life revolved around delivery sex services and information from the square box in front of him, one day finds himself caught up in a contest between gods. His vulgar thoughts caught the eye of the God of Thieves, and unbelievably, he was reincarnated in another world as a "Thief Girl." The will branded upon Eiji – adorable in appearance yet a king of depravity on the inside – was to harass both "The Hero," agent of the God of Warriors, and "The Demon Lord," agent of the opposing God of Sorcery. Luring the girls of this other world into intensely romantic (yuri) situations to satisfy his own desires, and unfolding a life of grand victory, he also unleashes various acts of harassment in entirely unexpected ways against the Hero and Demon Lord vying for supremacy. What fate awaits this Thief Girl?!

Just that alone seems to be a weak approach, so I'll include another theme of this work as an "excerpt."

Lady Eris, I'm truly grateful to you.

Until now, we were treated like bitches in the dark alleys, enduring our revulsion toward men, trembling in fear of carrying unwanted children, and our only joys were the bread of the day and imagining our families eating it.

We are all women who, somewhere along the line, buttoned up our lives incorrectly.

But thanks to you, Lady, we are all now able to re-button them in the right places.

And with the "somewhat nice things" and "very nice things" you taught us, there's no fear of getting pregnant either.

The bathhouse is clean, and the clientele is reputable.

At the establishment, implicit rules favorable to us have also been established.

The Thief Guild protects us from stalker-like individuals.

Finally, we too have the luxury to think about "tomorrow."

I like my current job.

Making the gentlemen groan with pleasure is something I'm good at.

But Hanna isn't like that.

For a woman who's fallen for a man, this job is heartbreaking.

Then shouldn't we help those who can 'clean up their act'?

Do you understand, Lady?

The entire story is much like this, I suppose. Though it's a mix of lesbians, Takarazuka-style women, homosexuals, gay men, effeminate men, and heterosexuals.
