Liza is a three-hundred-year-old blizzard dragon who spent her life as a reclusive shut-in, reading books inside a cave until adventurers drove her out. After being rescued by Haruto Zenfis, she becomes his second servant and quickly adapts to a new role. Possessing a remarkable capacity for learning, Liza becomes proficient at household tasks after only a little instruction and soon serves as Charlotte Zenfis’s personal maid, drawing on her quick memory and extensive knowledge. Her personality is calm, serious, and studious; she enjoys reading and acquiring new information. Influenced by the fenrir Flay, Liza comes to believe that Haruto is the reincarnation of the Demon King, a conviction that shapes her loyal devotion. As the story progresses, she joins a small faction alongside Flay and the character Johnny to fight evil and uphold justice, particularly after Charlotte begins masquerading as a magical girl. Liza’s notable abilities stem from her draconic nature and her formidable ice-based magic, which makes her a capable combatant in addition to her domestic skills. Her development moves her from a reclusive, bookish existence to an active participant in Haruto’s household and the broader conflicts that arise.
