Luna Howard is just your average girl who lives in Canada. Maybe what differs her from the rest was her lost memories.
She loves to do magic but didn't made a living out of it. Being a magician is more of a different persona for her. A persona which she thinks really close to who she really is.
Receiving the Tarot Card was the key to open new doors for her.
Meeting the other 4 Horsemen was another stepping stone in exploring new domain.
Especially meeting a certain Atlas who would never fail to rise either the limit of her temper or the beating of her heart.
