Mahou Shoujo Marin ~Chijoku no Zenra Dogeza~

She's cute and looks the part,
but Magical Girl Marin is totally powerless.
Every battle is a disaster! She just loses!
That means instant r*pe. Virginity? Pffttt.

Meet the losingest magical girl since Elle.
Pigbeasts to tentacles to townspeople
paint a coat of shame on the new cum-soaked "make shojo".

But Marin is not disheartened.
It's just so many shed tears of violent indulgence.
Today's another glorious day... to fail...
