Meiza Endust, formally Mather Enderstto but known as Mei, is the mage of her adventurer party. A consuming obsession with Cartado magic cards defines her, driving her focus and actions. Her distinctive blue hair and reserved expression create a tranquil presence. Gold decorative elements and clear materials, particularly in her skirt, highlight her costume's texture and detail. She wields a rod as her magical implement. Her story unfolds alongside her companions within the adventurer school framework. Key events showcase her role: exploring ancient ruins and facing a golem; tackling practical quests that escalate from finding lost cats to battling a giant spider monster in a tower; a summer trip blending leisure with a pivotal fight against an awakened evil god, defeated through teamwork; and her growing school integration fostered by shared challenges. Throughout these experiences—academic tasks, critical combat, and the sealing incident involving the Demon Lord that sets overarching events in motion—Mei's core fixation on Cartado remains. Yet, her consistent involvement reveals adaptability and a capacity for teamwork within the party dynamic, demonstrating growth through cooperative effort and shared trials.
