The speech bubble in the third panel has a polite and explanatory tone, so it makes sense to assume that Orin is talking about Koishi, and she/her or Koishi-sama would likely be used.
The problem is Kind Mita's chibis are defective, either spawning dead or broken as indicated by the one that wasn't dead constantly running in a circle. In all likelihood Kind Mita has been compromised and she's not aware of it. Of particular note she doesn't send you on the shortest route between versions, which Crazy Mita will tell you if you linger with her after nearly having the fridge land on you. As she'll comment that taking the rail car is actually the longest route between versions.
Considering how much she messes up I always took that as her not being as smart as she pretends to be (just like how she's not as kind as she says she is)
