Meh I'm not sure how users would feel about me suggesting things for this since I'm staff...
But I feel like we have a lot of these sorts of background elements in CI's already. "Oriental garden"&"Sacred Forest"&"Sacred Forest blossom season"
So for me I'd love to see something different. Something more tea/food item based than the setting itself.
Like Cat Cafes! I know their very different than traditional stuff. I just like the idea of a giant "CATuccino" or a Matcha Matching outfit.
I'd also like to see something done with Japanese sweets as inspiration. They're so cute you feel bad eating them!
