After death, a soul stands trial—not for his own crimes, but for those committed by the alternate personalities born from his fractured mind. Given one final chance, he's reincarnated as Zephiel Caelus Altherion, a forsaken prince with a mysterious job and a "useless" magic affinity. Branded as worthless and abandoned, Zephiel must uncover the hidden power of Creation Magic and his unique class, Ego Architect, which grants him multiple powerful personas—each with their own skills, affinities, and desires.
