Looking for manga

[1412]

I remember read this manga, it is about cute girls doing cute thing.

But the world they live in is actually the world where Demon Lord defeated the Hero and humanity long time ago, and the girls are actually monster girl.

The girls establish a club to research about human and the hero, which is just a myth for now modern world.
