Nero is the son of Medusa and the nephew of Enkodo. He is basically a star incapable of granting any wish, and sometimes he is bullied or discriminated by other stars for his inability. He has a best friend named Cyrus who does most of the talking for him, and sorta lives in the same house as he does. Nero struggles to maintain eye contact while talking with other stars except Medusa as they both share the same curse. He is shy and soft-spoken, having a demeanor of a cinnamon roll sometimes.
