Lammis is the main female protagonist and the first person to encounter the vending machine protagonist, Boxxo, in the story. She is a young hunter from a fantasy world where people receive divine gifts known as blessings. Her blessing is the Blessing of Might, which grants her extraordinary physical strength far beyond that of an ordinary person. However, she is initially clumsy at controlling her own power, often damaging things unintentionally.

In terms of personality, Lammis is lively, pure‑hearted, earnest, and somewhat naïve. She speaks with a warm, informal dialect and refers to herself in a humble manner. She is quick to act and can become overconfident when praised, leading her to neglect caution. Despite her impulsive side, she has a strong sense of justice and a straightforward nature, making her a trustworthy companion.

Her motivation centers on exploring the dungeon and helping those around her. She forms a deep bond with Boxxo, naming him and carrying him on her back, which not only allows him to move but also helps her better manage her strength by using his weight as a counterbalance. Lammis also has a close childhood friendship with Hulemy, a skilled magic‑item inventor, and eventually works alongside the adventuring group known as the Fool’s Parade.

Over the course of the story, Lammis develops greater control over her strength and matures as a hunter. She learns to rely on her partnership with Boxxo and gains confidence in her abilities. Her notable ability remains her immense physical power, which lets her crush rocks with bare hands, lift objects weighing hundreds of kilograms, and deliver blows that rival or exceed the special techniques of elite hunters. She does not possess magic or other supernatural talents beyond this divine blessing.
