Synopsis

Eugene encounters Mer, a human-like familiar spirit created by Senya, who reveals details about Senya's personality in her youth, her transition into a more research-focused mage, and the advanced nature of her magic. Mer also confirms Senya's lack of contact with Vermouth or his family post-Helmud, and that she retired discreetly with her whereabouts remaining unknown, even to her students and servants. Furthermore, Mer discloses that the magic tower tried to access Mer's memories seeking Senya, who used to be close to Vermouth, and details the nature of Senya's powerful Witch Craft magic.
