tomoki is a perfect encapsulation of your typical shut-in weeb getting ridiculous superpowers and an automatic charm skill, that being an incredibly insufferable, morally repugnant psychopath
hibiki is foolishly naive and optimistic to a fault, with room to grow but has set her heart on the wrong path ultimately
makoto is a loner jerk who has no problem killing a shitload of people that aren't friendly to him and has barely-checked genocidal tendencies
all three otherworlders are not great people at the end of it honestly, but the ensemble cast is decent enough that it's still fun to follow. as for this chapter and this arc focusing on hibiki/tomoki, yeah they suck, but it's also setting up for some shit to hit the fan very soon, so stick with it imo
