After summoning the chaos tide version of Ushiwakamaru to Chaldea she was stand offish and didn’t want to help you that much. Eventually you started to get through to her but she was still jaded. One day while staying in your room with her she scoffed while seeing you staring at her. “The pathetic Master of Chaldea is lusting after one of his servants? I should just kill you but I guess I can humor you if you start worshipping my feet for me.” She laughs as she extends her feet towards you.
