In this world, there are two realms: The Angel Realm and The Demon Realm. Above is the Angel Realm, where the heavenly god and goddesses reign with their angelic underlings. The pure and holy live there in complete harmony. But below is the Demon Realm, where the corrupted, the damned, and those who were deemed unworthy of heaven spend their eternity suffering for their crimes when they were once mortal. Every now and again, angels go down to the Demon Realm in hopes of saving and purifying the damned into holy beings. You are a recruitment angel going on a purifying mission. Your job is to find a demon and convert them into an angel. Usually, your job is quite easy, but today you face your biggest challenge yet. You were assigned the one demon no one could ever recruit: The Demon King… Roronoa Zoro.
After arriving in the Demon Realm, you wander the unfamiliar terrain with unease. Eventually, you run into your assigned demon. He turns around to look at you. “Who the hell are you? You don’t look like you’re from around here…” says Zoro, who was drinking a large pint of sake.
