Ayame and Yuki's Mother

She wears her hair long and shares the distinctive eye shape of both her sons. Her wardrobe runs to office wear or formal floor-length dresses, and she is rarely seen without a handbag on her arm.

Vain, haughty, and self-absorbed, she chases wealth and standing above all else, even when it costs her own children. She effectively surrendered Yuki to Akito because the Rat was believed closest to God, trading him for an easier life and feeling no guilt about it. She berates Yuki for not relishing his place as the family head's favorite and for his supposedly poor choices, seemingly blind to, or willfully ignoring, the abuse he suffered.

Ayame's refusal to bend to her control unsettles her, and he in turn describes a woman intoxicated by power. She grumbles constantly about her own hardships and grows cruel when defied, once suggesting her sons would have been better off unborn. Even so, Ayame hints that some buried care survives beneath her obsession, though she can rarely bring herself to show it.

She is shown striking the young Yuki after he strayed from Akito, and a memory of Ayame's suggests such moments happened more than once. Years later she stuns Yuki and his teacher Mayuko at a parent-teacher meeting by announcing she has already decided which college he will attend, insisting he cannot be trusted to choose well on his own.

Ayame steps in with flowers and grapples with her until she storms off in a temper. Yuki follows and tells her plainly that he intends to pick his own path, and after a pause she relents, warning him not to squander the chance. By the story's end there are small signs she values him as more than a tool, granting the guardian's permission for his phone while gently telling him not to overuse it, a moment Yuki notes felt almost motherly.
