Dojima Otaro / "Eight"

He is a handsome number one host and goes by the alias 'Eight'. He used to work at another club under the alias 'Seven', but was 'banned' for stealing customers from his colleagues. He would use any number of women to achieve his goals and cut them off when they were no longer worth it.

Twelve years ago, while on board the Prometheus, a cruise ship captained by his father, with his younger brother Kota, an accident occurred and they were swallowed by the large amount of water that flowed into the ship. Wantaro was rescued safely, but Kota, who was also involved in the accident, disappeared, and he was forced to pay compensation on behalf of his father, who was sentenced to prison for the accident. He has become a scumbag who is obsessed with 'visible things' such as money and power.
