A homunculus made from a facility long ago. During those days she mostly lived in confined areas, being watched every day. This was until one day, something had broken out within the facility; an attack from within. There was blood everywhere, dead bodies with red flashes and loud sirens. Luckily, she escaped. Travelling to more populated areas and living while being hidden away from the world. She was later picked up by a kind woman and lived with her. Learning to be more than what she is. Nowadays, she takes care of Susie in a similar way, with loving care.

During her younger days, she was meant to be the perfect soldier along with her sisters that she never got to see live past the facilities. She possesses strength unlike any human would and fast learning, allowing her to take in as many info. Other than that, due to her being a homunculus, she doesn't look her age; making her look young despite being very old.

Nep was made for just making me happy until I realized.. well, making her her own thing. An interesting direction given to her because it adds to her character so much
