Becoming the Overpowered Protagonist in a Crossover World

"What are you after?"

"Do you want the truth or a lie?"

"A lie."

"To become the king of the port underworld."

"And the truth?"

"To become the king of the world."

Oath.

I, Yutielo Vittorio Romano, of the Clan of Kings,

acknowledge your sincerity and loyalty,

and grant you the greatest token of affection befitting them.

I swear to you a friendship that will never change in this life,

and a love that will endure until death.
