I, the Demon King, Joined the Justice Group

The Abyssal Demon God descended upon the Myriad Worlds, plunging them into endless darkness.

One day, an Alliance of the Righteous was born. It brought together the young prodigies of the Myriad Worlds, who trained diligently in the martial arts under the guidance of the Goddess of Light.

The righteous ones made eradicating the Abyss and slaying the Abyssal Demon King their ultimate goal.

Lan Chi, the Abyssal Demon King himself, accidentally wandered into the Righteous Alliance's group chat. Out of sheer mischief, he personally trained the righteous ones, who revered him as the Holy God.

Jin Shanshan: "I believe that under the Holy God's leadership, we'll be able to kill the Abyssal Demon King one day. No! Great Holy God, I don't want to become a monk!"

Kasumigaoka Utaha: "The Holy God is so magnificent, truly the embodiment of light."

Many years later, when the righteous ones invaded the Abyss, they discovered that the Holy God they respected and worshipped most was none other than the darkest Abyssal Demon King.

Rem: "Ah, my whole worldview has collapsed. How could He be the Demon King?!.."
