Yumiko Okumura

Yumiko arrives already formidable: a corporate lawyer turned survivor who has walked out of the ruins of her old life with her competence intact. Sharp-tongued and unsentimental, she's protective of her found family, quick to size up threats and people alike, and unimpressed by posturing — she wants safety for the people she's chosen, and she'll argue anyone into the ground to get it.

Matsuura plays her with a dry, exacting intelligence that cuts through the show's usual grimness — she sounds like someone who used to win arguments for a living and still does. The writing lets her be capable without making her invincible, and her loyalty reads as chosen rather than assumed, which gives every alliance she forms real weight.
