I Am Dark Lucifer, the King of Ultra’s Adopted Son from the Start

Kumano: I'm Mephisto? And now you want me to fight Dark Faust? What the hell! How is Faust even darker than me?!

Space Beasts: Those artificial fried-chicken freaks can get lost! Our true leader is back! We'll repay every humiliation and every grudge from the past. Wait, first let me take care of a few overrated losers from Monster Fight.

The protagonist: Where did this impostor come from? And you, Nexus's girlfriend and Noah's girlfriend! What are you trying to do to me?

A crazed look flashed in Carmeara's eyes. "The first darkness in the universe? Then my three million years of accumulated power are a perfect match for you! What do you mean, Dark Calorie Bar? Get lost!"

Ultraman King: I give up, I give up! I can't control this son of mine!
