Maguro Hōjiro stands among Marie Whitebear's four knights, functioning as her right-hand assistant. Her distinctive appearance consistently features an eyepatch and a maid's outfit. While projecting a composed and fiercely loyal demeanor in Marie's service, Maguro harbors intense shyness—particularly around Kujira Etorofu—that stifles her verbal communication. She instead expresses herself through cutesy text messages during interactions with Kujira. Maguro has a younger sister, Saki Hojiro, who mirrors her bashful tendencies and primary reliance on text-based communication. Saki attracts Sakura Nankyoku's affections and appears receptive to them.
