"I've been watching you, little angel," Chaos explains, Nico dumbfounded in his place. "I've overseen you your entire life. And, I am intrigued. You have great potential. I would like to appoint you by my side."

"W-hat..." Nico attempts to form words. "What would this 'Angel of Chaos' gig consist of?"

"Immortality," Chaos responds, almost too quick. "Fighting with me, and for me. Being at primordial status. Casting away your identity as you become something new."

Nico considers it. A new identity... A new life...

"If I said yes?" Nico asks.

"Then you come with me, saying good-bye to your home and friends, as you make new friends in a new home, and protect the universe at the highest level or standards."

"And if I said no?" Nico arches an eyebrow.

"You may continue to live your short life as you please, and all memory of this incident will be erased."

Nico nods. Make new friends in a new home, he said. And the power... to finally be the hero I was never able to.

Hesitantly, the boy nods. "I'll join you."

Chaos' smile widens. "Well. Welcome, little angel, to your rebirth."

Nico's arm wavers as his shoulder blade feels hot. "Ah-" Nico drops to the forest floor. Rebirth? A sheering pain rips into Nico's back, and he screams. "AH!"

As soon as the pain had come, it ended. "Welcome to the Angels of Chaos, ángelos tis elpídas."

Translation:
ángelos tis elpídas is "angel of hope" in Greek (sorry for the lack of capitalization).
