Nyx

ニクス

Nyx is a young man studying Space-Time Manipulation in the Luxuria Belt Region. He and his twin sister, Mira, do not share a birthday as they were born moments apart, right as the date changed. Ever prudent, preferring to act only after careful and thorough deliberation, he holds the belief that time is finite. He respects his older sister's talents, although the two are in many ways polar opposites. (Source: The Alchemist Code Wiki)
