Léon, known in the original Japanese as Seiju Suzukaze or by his full European name Leonhart Rosenheim Michaelis Suzukage, is a central figure in the anime Gekkō no Pierce: Yumemi to Gin no Bara no Kishi-dan. He is a high school senior in Japan and a former captain of his school’s soccer team, where he played as a goalkeeper. Léon is the head of the prestigious Michaelis family in Germany and the commander of a secret society called the Silver Rose Knight Order. His primary motivation is to recover the scattered sacred objects known as the Three Universe Four Holy Spirits’ Sacred Objects, which were lost from the order. He enlists the help of the main character, Yumemi Satō, along with Hiroshi Takama, Aki Kōsaka, and Takao Reisenji, after a cursed earring attaches itself to Yumemi and causes the others to transform into animals under certain conditions. Léon was abandoned as an infant in the garden of the Michaelis estate and raised as an adopted son; later in the story it is revealed that his biological parents are the head of the rival Aldi family and Julia, the youngest daughter of the Michaelis family head. This background gives him a complex personal history tied to the order’s conflicts. Throughout the story, Léon acts as a calm and capable leader, guiding the group through supernatural challenges. His role is both that of a mentor figure and a driving force behind the quest to break the earring’s curse. While the single OVA offers a condensed version of his character, the original light novel series provides more depth to his development, including his struggles with his origins and his responsibilities. Notable abilities tied to his character include his knowledge of the order’s secrets, his leadership skills, and his physical agility from soccer, though the anime does not focus heavily on combat techniques.
