Mukou Aoi♀

Given that she’s a character who focuses on getting in contact with god through her chants of "touarururururu~"s, it's no wonder that Aoi is someone whose presence isn't noticed by others – or rather, ignored. A classmate of Shin'ichi and Miyuki's, her brain is full of nothing but games. Going beyond casual jokes and spouting dated memes like other visual novel savvy characters, there's something inherently destructive about the way our mysterious little denpa darling has to liken everything in their lives to a visual novel. Shin'ichi and Miyuki have a stunted conversation? That's a flag. A friendship defining moment happens? You better save to relive the memory later, because the OP is probably going to play any minute now.

Poor at socializing, both Shin'ichi and Miyuki feel like she's unable to draw a line between reality and visual novels, having them seamlessly merge. While she may seem like a poorly written denpa character coming off as deliberately unhinged from the outset, the reader can't help but wonder if there's more to her than meets her clouded eyes.
