Luna, younger twin to Sora of the Fairy Tribe, once guarded the Lost Forest with the Shield of Truths until her abduction by the Shadow Knight, a demonic enforcer of the Demon Lord’s forces. Her capture plunged Sora into anguish until Rein Shroud’s group defeated the knight and secured Luna’s freedom. Both twins then forged pacts with Rein, joining his party as his third and fourth allies.

Mirroring Sora’s appearance, Luna bears blonde hair, luminescent wings, and a blue flower pinned to her right temple. Though her visage suggests youth, she exceeds two centuries in age. Her personality clashes with Sora’s restraint—teasing wit, mischievous antics, and flirtatious jabs at Rein spark frequent scoldings from her sister. Yet her devotion to Rein remains absolute, matched only by her contempt for manipulators like Edgar Fromware and Arios Orlando, the disgraced hero who betrayed Rein.

A master of fairy magic, Luna manipulates spellcraft to amplify its potency. Her signature techniques pierce memories (Memory Search), unleash concentrated light strikes (Flash Impact), and summon protective barriers (Gravity Wall). The bond with Rein nullifies curses and instant-death magic against him. Guided by Suzu, she sharpens Flash Impact’s destructive focus by sacrificing its range.

When Arios escapes imprisonment to ally with demons, Luna dedicates herself to his eradication, shielding Rein while pursuing justice. Though her past remains shrouded, her journey emphasizes deepening alliances and confronting threats from Arios and the Demon Lord. Amid playful banter, her resolve to protect Sora and the party underscores a steadfast sense of duty beneath her carefree exterior.
