Kanaria will develop the ability:
偽妻 - Nisetsuma ("Fake Wife")
Having tasted Sou's home cooking and getting in contact with the lingering saliva on his chopsticks, Konoe Kanaria developed a powerful synesthesia where she can taste Sou's words, scent and vision. She also knows how being kissed by him all over would feel like. Using her combined senses Kanaria can detect Sou's presence from afar and find him wherever, even if he leaves her side. This allows her, under any condition, to stay calm and collected and claim her spot in acting as Sou's newlywed spouse (fake).
Ohohoho...don't think you can ever run from this Konoe Kanaria, for we are bound by fate and food.
EDIT: and if you believed this, Kanaria's power already got you...
