Aim is a prostitute who lives in a slum and is often gang-raped. She has a hard life but wants to have a luxurious life and escape from hardship.  One day, Aim received advice from a procurer who is in the same brothel to meet with a master who has black magic. He tells Aim to do the ritual. “Black magic mask”, but before the master starts the ritual, he tells Aim the conditions: “In this world nothing is free. If you are thinking of doing it, you must accept the consequences.”
