SHE LIKES KOISHI. She thinks the girl is cheerful, friendly, and upbeat, which she enjoys, and there isn't the worry that she's reading into Nanoha's fondest and most intimate memories like there is with Satori. She's a bit worried that Satori is sheltering Koishi which may make some things harder on her - and concerned for the girl's mental health in general - but that doesn't mean she isn't pleasant to stay around.
