Girl times...? 🥺 Girl times!! 😊 They could just do a food tour maybe?! Cake shops would get her nostalgic because she does like sweets and have a baker family background so we can literally do spicy&sweet, it would be cute and silly and a good way to unwind/talk about whatever too. We could potentially combine stuff you mentioned in your plotting comment too, she'd give her gift ideas and humor Misa going off about her bf? It's so hilariously terrible that "yes we only met earlier this year, it was love at first sight, he's obsessed with me" SORT OF... applies to her too to a uncomfortable degree tbh (like not even 2 weeks time span thanks canon), she does Not want to talk about it however (it's Tragic, closes my eyes) but maybe Misa could pick up hints and try to get nosy?

She's totally there otherwise for potential self defense brainstorming/training, though! Ciel doesn't want the normies to force themselves to fight when they didn't used to do it before but also acknowledges their current situation kinda forces their hand, so she'll do whatever she can to help her prepare u_u we have options!!
