Okarun may be the most visually repulsive nerd i've seen in manga in quite a while, both in terms of mannerism and appearance. I would praise the author for it if the manga was about a bunch of fun nerdy dudes dicking around supernatural with hoes far the fuck away, but this awkward, utterly retarded "romance" is by far the worst thing about the story because there's not a single chance in hell Momo would ever fall for someone like him, or even talk to him, or treat him as anything but dirt.
Thankfully the author has shoved this particular subplot into a dusty corner and will probably spend another good hundred chapters before it shows its ugly head again.
