Matsunaga was a very convincing man and managed to persuade Ogata that her family hated her due to bringing dishonour with her suicide attempt, she moved in with him on release from hospital.
Matsunaga had created a futon company named "the world" and began operating from a purchased property in 1985. his vindictive side began to show, he would torture his employees by electrocuting them and playing on their fears by screaming at them that there souls were being stolen by spirits and using words such as: samsara (meaning "continuous flow",  the repeating cycle of birth, life and death and reincarnation) and  shouting references to Kami (the spirits or phenomena that are worshipped in the religion of Shinto)
