Kurumi Narumi

Serving as both Seisa’s dedicated maid and Eruna’s instructor, this character maintains a notably stoic and deadpan personality. While she frequently displays a stern disapproval of Eruna’s chaotic behavior and antics, she reveals a much gentler, softer side when interacting with Seisa. This contrast between her rigid professional discipline and her underlying warmth toward her mistress defines her unique role within the story's social dynamics.
