For Miyata, who doesn't care about women or money, there was a girlfriend he could manipulate to suit his own convenience. However, he found out that her younger sister was his type. Determined to make her his own, Miyata devised a plan: one night, while she was asleep, he sneaked into Azu's room and used an erotic video of her sister, which he had filmed as a hobby, to blackmail her. Although Azu resisted, she eventually gave in to his advances. Later... Miyata summoned Azu to his home and began training her with aphrodisiac drugs to turn her into his sex toy.
