OMG Akemi is delulu af, when she gets divorced who in thier right mind would make her the main wife, even if its not the Benitsubaki clan. It's her 2nd marriage even if she is from nobility and has a high spiritual power. But I imagine with the time period, if she gets remarried it would be to a widower's main wife or as a concubine. BESIDES, I can't imagine Yako getting a HER as a concubine, much less a wife after what she did to Nanao. So yeah, she's very delulu.
