After numerous trials, Iruma finally earned the System's Epic Achievement, [Demon King in the Making], and arrived in the Demon Realm.

Though he was a human who should have felt like a stranger there, everything seemed familiar.

The demons, who had long awaited the Demon King's return, paid their highest respects to Iruma as he came home.

"He is the greediest and gentlest of Demon Kings.

His absence left the demons without a leader, and his return will restore the Demon Realm's glory.

He is the ruler of the Demon Realm, the supreme sovereign of us all."
