And where did exactly they state that he has any skill to charm vampires? This is one of the biggest inconsistencies in the novel, what is and what is not affected by a skill that has a targetting restriction. Bees? Affected by "Death Charm". Vampires? Treated as insects, just like slimes. When he arrives at the ghouls, he should not have any "Charm" skill that can affect them since they are not related to death in any form. You can say that vampires are descendants of an undead (even though Zakkart had little to do with other undead, and he was more of a golem since he lacked a soul) and thus related to death, and by extensions, ghouls are too, okay. When he meets the Scyla, "Death Charm" triggers (this is stated in the novel) for no reason, no "Abyssal Guider" at this point, which would actually affect the Scyla. I can't omit the bees, that part just blew me away because of how pointlessly convenient it is, and the exuse of a reason the author gives you. Don't get me started on the skills he gets and how poorly designed they are (Bravers have some stupid skills too, and they have overlap, something that should not be possible. And they have skills that are contradictory with the narrative, but you can blame that on Rodecorte. And yet, their skills mostly make sense). Vandar can become an insect master because there are no insect tamers ... Except a race of them, except there is actually an insect tamer that's not part of the bug race. And because there is a tamer, but not a master, he can get the master job, skiping the tamer. And there is no master after who knows how many generations of the bug race being tamers. And after all of that, his master job works completely differently from other tamer, or master, jobs (other tamers/masters can't do the equip thing). And let's not forget that an arbitrary UNINFESTED vampire gets affected by insect equip for god knows which reasons. Etc. Vandar's part of the story is very janky past the repopularion of Talosheim arc (when he leaves for the duchy). Up to that point it's fun and intresting. After that it's convenient plot twist on top of a convenient loophole, on top of a convenient coincidence. The Origin sections seem much more natural at that point.
