So now that I think of it, doesn't she look a lot like sayori_(character) ?
Also, the bottom bubble says " ぷにカワ作家さより初登場 ", What is "Puni kawa"? Some sort of portmanteau of puni kawaii, or squishy and cute? Google isn't being all too helpful on the matter, so I can only assume it says "Squishy and cute artist, Sayori, makes her Debut!"
