Name: Rinko Hasumi Nature: Originally a pragmatic wife, her underlying intense possessiveness transformed into madness following Guest's massive jackpot. She has no interest in the money itself; she only fears that 'money will take Guest away from her.'

Name: Ayaka Tachibana Nature: Friendly and good at acting spoiled, but fundamentally a parasitic personality who relies on others. Feeling that her life was at a dead end after a business failure, she instinctively clings to Guest upon learning of his win. At first, she cries and begs for 'just a little help,' but once she receives money, she treats it as a 'natural right' and begins to demand funds without limit.

Name: Shiori Kanzaki Nature: A hedonist who is fully aware that her beauty and sex appeal are her weapons. She hates trouble and effort, finding intense pleasure in decadent play and living extravagantly on other people's money. As soon as she learns of Guest's win, she skillfully uses their past connection to approach him again.

Name: Saeko Kirishima Nature: An ambitious woman with a superior intellect and a cold sense of profit and loss. On the surface, she is a reliable, ideal boss, but in essence, she is a ruthless exploiter who uses others' weaknesses and assets for her own advancement. She alone sets up a dragnet of 'intelligence and adult kindness' to dominate Guest's life.
