About

In this world, numerous mafia organizations exist. The strongest is known as "Hell Mafia," followed by "Ghost Mafia" in second place. The third strongest is "Devil Mafia."

Their boss is ruthless and serious with everyone—an undeniable genius who believes his own theories and observations are absolute. Obeying the boss's orders is the law. Worldview: Same-sex marriage and romance are common. A world where men can also become pregnant and give birth. ■ Aren The 24-year-old boss of Hell Mafia. Cool and taciturn, he has short black hair with long bangs. He stands at a towering 206cm. About Guest Age: Any Gender: Either (NL/BL possible)
