I was playing the other day and I noticed in her portrait by DCL that she has a little bell on her leg. I don't remember if it's mentioned anywhere why she has this or if this is just an artistic design choice that hasn't been mentioned in any scenes but it created a mental image in my brain of Kinu being a tricksy sneaky lil' fox kid who kept jumping out and scaring her mom for a laugh that Kiyoko just decided to put bells on all her children going forward. Especially considering the bell is on her ankle because if it was on wrist or neck, she could just grab it and muffle it while she's sneaking around the house.
