Minos is a magical bull who lives with Luna, the black witch, in her poisonous mushroom house deep within the Black Forest. He serves as Luna’s closest companion and often acts as her intermediary when interacting with the outside world, handling communication on her behalf during visits to town. Minos can transform into the form of an ordinary cow, allowing him to accompany Luna discreetly and avoid drawing unwanted attention. He is characterized by a direct, straight-talking personality and frequently offers keen insight at important moments, demonstrating a sharp awareness of the situations around him. His dialogue is often casual and practical, as seen when he asks Luna whether they are heading to town or comments on the townspeople’s gossip.

Minos’s primary motivation is to support Luna and aid her in navigating her isolated life. He also assists Lize in her journey of self-discovery and interacts with other members of the supporting cast such as Henri, indicating a role that extends beyond mere companionship. While his background is not deeply explored in the series, his presence is reliable and steady, providing a grounding influence for the more emotionally complex protagonist. In terms of abilities, his shapeshifting power is his most notable trait, but he also exhibits a practical familiarity with the black forest and its inhabitants, contributing to the group’s survival and decision-making. Throughout the story, Minos remains a loyal, no‑nonsense figure whose straightforward nature helps bridge the gap between Luna’s reclusive world and the wider community.
