Ginji Hirai

He works as a fixer in the underground society under the alias "Silver King" under the nickname of "Gin". He has outstanding capabilities in every respect and a unique philosophy of life. He draws Morita into the underworld as a man who fits the "conditions" and expects him to grow and develop his talents. With his demonic train of thought, he squeezes money out of the weak and the wicked, but his greatest ambition is to use powerful politicians such as Izawa to control the country's economic world, believing that it takes a greater evil to defeat evil.
