User blog comment:HowardBonty/The Spy at UA - My Theory/@comment-35690462-20180603210237

That's been my theory for a while, actually. It's seems plausible that the invisible girl would sneak around. I wish we got more Hagakure, though, she's such a cute character that needs love and protection. I still question how she got into U.A in the first place, unless she turned off the robots. There's no way to really determine the traitor yet, though, we just have to keep waiting.
