[If there's someone that definitely doesn't get deterred by the rainfall it's Yona, who noticed the start of the rain from indoors when it was still fairly light and went to the shopping district with the express purpose of getting some back up umbrellas for those that might be stuck outside in need of them.
She's still carrying several with her when she notices Lili, for a moment too surprised to question the other girl's terrible sneaking around. LOOK SHE REMEMBERS. KINDA. Not exactly.]
