Kasumi Kagami

Kasumi Kagami is the older sister of protagonist Kazuya, stepping up as both household manager and legal guardian whenever their mother is absent. She stands as the only person capable of keeping Kiriha in check within the family. While she projects an image of warmth and competence on the surface, she harbors a deep, almost obsessive attachment to her younger brother behind closed doors. Beyond her exceptional homemaking skills lies a formidable martial talent that she keeps carefully concealed. Operating under the title of Exorcist General alongside the tsukumogami Saori, she engages in supernatural battles while dedicating herself to protecting Kazuya from the shadows.
