Glass

Glass is a formidable warrior from a parallel world in 'The Rising of the Shield Hero,' wielding a black iron war fan with overwhelming combat prowess. She first appeared as an adversary during the Waves of Calamity, driven by the sole purpose of protecting her homeland. Among all the heroes, she recognized only Naofumi Iwatani as a true hero worthy of respect. Guided by a strict code of honor and an unyielding warrior's spirit, she eventually reconciled with Naofumi after their misunderstanding was resolved, transforming from a fierce opponent into a powerful ally united in defending both worlds.
