Synopsis
A brother and his sister were deeply in love with one another, but their relationship was doomed from the start. The sister suffered from an incurable illness, and the brother did everything in his power to save her. For a time, things seemed to be going well, until he met a girl. With her arrival, his circumstances shifted dramatically, and his sister's condition suddenly worsened, ultimately leading to her death. Yet his love for her was so immense that he could not let go of the memories they shared. Feeling betrayed by god, he defied his faith and sought out a greater power: a demon. The demon agreed to help him, but only in exchange for the blood of a virgin—his new friend.
