Looks like she struck gold with Lydia finding that treasure trove of free old stuff and putting it in Ruri's dimension. Reminds me of the days I used to go to antique stores or thrift stores for a bargain, or flea markets where it wouldn't be unusual for a stall to give you free stuff they couldn't sell but didn't want to bring back upon closing up. Being a pack rat, I always loved finding old but useful stuff, especially glasswares or rarer finds like silverware cutlery.
