HH System

I was a young man on earth, living a normal life until one day I woke up as the princess of the Pergrande kingdom of Earthland, Lina Pergrand. Fairy Tail... That was not all, however, I had a system of sorts as expected; HH System... Human Harem System. As it says, the system was designed by some omnipotent entity to help humans get harems... Every target I made fall in love with me would give me a shard, and every shard could give me things from the store; From powers to body modification to universe traveling... Everything was possible. And my first target was... Erza Scarlet. How was I supposed to make her fall for me while I was in a girl's body?! Sigh... I decided to chase magic, hoping for the best.
