Yikes, those pathetic losers happy to simp for Touka to her face while at the same time sexually harassing her need to have their faces kicked in prison. Yunno what, in any other mainstream mangas, the airhead is a funny trope but I can appreciate the realistic and gross take here. Touka, a beautiful young woman, was shown to be so clueless that she got lost in her own city, without any money.
Nothing cute and funny about it, this is terrifying when there's far too many men seeing women as prey and always in the lookout for vulnerable ones. Not sure what's her deal, if she's autistic, indeed stupid, or if she has a completely warped assessment of people because whatever happened in her family (controlling father so never had much opportunity to make choices for themselves, so all they got were a few burst of unhealthy expression?), but yes, unfortunately, we're still far from living anywhere women can afford to let their guard down.
Frankly, her sister Kaho is not much better in some aspects, but she's been lucky to have found someone she can trust in Shirasawa, while she also affirmed herself. So instead of scheming to undermine that, her sister ought to be inspired by it or benefit from their company and advice too because she seriously needs it.
