Some piece of furniture who corrects grammar among other things. When she re-watched the series she cried through the whole entire last episode. For some reason, she has a strange obsession with art depicting anime girls in images that're mostly scenery and look melancholic. A good example of this is this fanart drawn by Miso Pan.
Also, while she is obsessed with correcting grammar, she can't seem to write anything properly on her own.
