Shodai Roshutsu-Kei Mahou Shoujo: Lunaly☆Lily

An incident destroyed Luna's trust in people and now she's anti-social.
One day a strange creature called Shabi shows up and attaches to Luna.
She's not interested in its talk about becoming a magical girl...
But then a monster called Libido attacks.
For her own protection Luna must sign a contract with Shabi and transform.
In the middle of the battle, the media shows up and broadcasts the whole thing.
Now Luna is under contract AND the whole city knows her secret identity.

Can Luna defeat the Libido?
Can she bear the shame of public humiliation?

[From DLsite English]

In order to erase everyone's memory of her role as Lunaly Lily, Shabi explains to Luna that she must gather enough energy as a magical girl to cast the memory erasing spell. He gives Luna increasingly embarrassing tasks such as wearing a micro bikini to the pool all the way to walking naked in public in order to increase her S Energy levels.
