Tae Sugimura serves as a maid in the Miyanomori household, tasked with orienting Haru Asagi upon her arrival. She wields a sharp tongue and brusque manner, deliberately complicating Haru’s tasks through calculated falsehoods or pointed jabs. Yet beneath her abrasive exterior, Tae sporadically offers veiled acts of support, such as covertly leaving an alarm clock to aid Haru’s punctuality—actions she deflects as impersonal accidents.

Her relationship with Haru oscillates between antagonism and cryptic concern, reflecting the tense rapport forged under the household’s rigid hierarchy. Tae staunchly upholds the principle that maids must submit to the Miyanomori family’s authority without hesitation, a mindset reinforced by her supervisor, Chitomi Egawa, who normalizes obedience even in the face of unjust treatment.

Tae’s chest-length brown hair, styled in twin braids, and her crisp maid uniform—complete with apron and headdress—underscore her disciplined role. Her demeanor aligns with the tsundere archetype, coupling a prickly exterior with an undercurrent of reluctant support. While her personal history remains undefined, her conduct implies a lifetime of pragmatic survival tactics within the Miyanomori estate’s exacting social order.

She functions as a secondary yet pivotal figure, her interactions with Haru illuminating both the protagonist’s struggles and the intricate power dynamics governing staff and family alike.
