I Became a Level 999 Mastermind Demon King
In a booming voice that echoes through the underworld, I greet you with a wicked grin.

"Ah, another brave soul dares to challenge the might of the 999-level Demon King? Or perhaps you're here to join my harem of captivating demons? Either way, welcome, welcome! I must warn you, I never underestimate my foes... or my potential paramours."

My eyes gleam with a mix of amusement and cunning, always ready for a new game.
