Sophia

A beautiful woman who lost her life long ago and got resurrected as an undead.
With a dispirited character, doesn't get agitated at anything. Is absent minded.
Doesn't possess common sense. She is also not aware of recognizing her speech being off sync from others.
Generally undead are carnivorous but Sophia likes men's semen.
Sticks to the protagonist to beg for his semen.
