Nerva Martillo, a student at St. Friedeswiede Academy for Girls, commands a group of bullies targeting Melida Angel, masking an obsessive infatuation with destructive behavior. Her inability to articulate these emotions drives her to cruel tactics, a warped effort to forge a connection. This dynamic fractures when Melida awakens her mana and defeats Nerva in combat, compelling the latter to confront her actions. Nerva issues a sincere apology, shifting her strategy to build a genuine friendship. Their alliance solidifies during the Luna Lumiere Selection tournament, where they partner as teammates, combining strengths to pursue mutual objectives.

Nerva’s appearance is marked by light reddish curls tied into coiled pigtails and amber eyes that mirror her fiery disposition. As a Gladiator-class combatant, she wields the Garrick Hammer, channeling raw aggression into her strikes, a reflection of her standing within the academy’s competitive hierarchy.

Her past remains sparsely documented, with minimal insight into her family or life before enrollment. Narrative emphasis rests on her fraught relationship with Melida, tracing her journey from antagonist to reluctant ally. This arc underscores her gradual self-awareness and willingness to atone, pivoting from cruelty to collaboration as a path to redemption. Her story remains anchored to the central narrative, with no expanded exploration in supplementary media or spin-offs.
