Magical Girl Luliel ~defeated sisters~

Humanity was under attack by an army of inter dimensional monsters.
Men were killed or enslaved in horrendous conditions and woman were used as seedbeds to give birth to monsters anew. A world in chaos...

A few years of monster tyranny pass----

And another creature appears from the other dimension.
Giving humanity powers to fight against the monster army.

Fighting against the monster legions in their dazzling outfits.
Humanity called these saviors, "Magical Girls".
