In chapter one we have, violence, sexual assault, creepshots, stalking etc. Also if you look at the last panel, Otaku is lying down in a closet next to a sukajan (clothing popular with biker gangs/student gangs) and a fair amount of makeup (presumably to change her appearance). So otaku was likely lying about picking up martial arts and the rest... Yeah this gonna get twisted fast... This is just a repeat of the author's shtick of covering up the f-ed up shi with moe and uwu. At best he just changed the ratio of the two. I have no hopes.
