Necromancer Vol. 1

A brother and his sister are madly in love with each other. However, their love would not last forever. Suffering from an illness that can not be cured, the brother does everything he can to help his sister. Things were going well until one day he meets a girl. With her introduction, things quickly changed for him and suddenly his sister’s illness takes a turn for the worse and eventually leads to her death. However, his love for her is far too great to forget his memories of her. Feeling that god has betrayed him, he goes against his teachings and turns to a greater power…the demon! The demon agrees to help him out in exchange for a virgin girl’s blood…his new friend.
