Okay, listen I have a theory I used to hint about this a lot on my main blog but like what if Mineta is the traitor. Like I shit you not. If you really think about it no one would expect him because Mineta is pathetic and useless they would just think he was just some perv. Mineta could very well be the traitor because doesn’t have much personality and like no one would even expect it. Not to mention him being the traitor would finally give him some story that isn’t centered around being a fucking perv.
Like we all hate Mineta right? So we wouldn’t be quick to suspect him cause we’re too worried about it being a fan-favorite and actually likable character. I’m not so sure about what the eastern fandom thinks about Mineta, but I get the feeling that he’s supposed to be a funny guy or whatever. I also know no one ever suspects comic relief to betray the main cast.
