Dude, if the majority of the characters are going to be this brain-dead retarded than this manga is just going to be too infuriating to read . "Ehhh? What do you mean this is a trap? 🤔" "What's the matter? 🤔" "What the hell are you talking about? 🤔" A "GIANT MONKEY", OR SOMETHING AT LEAST, BUTCHERED LIKE A 1/5th OF YOU JUST THE NIGHT BEFORE AND YOU'RE ACTING LIKE THIS IS A NORMAL DAY WHERE YOU'RE JUST BEING INCONVENIENTLY ANNOYED BY SOME ATTENTION-CRAVING CRAZY ASSHOLE. Logically, a group of people in such a situation like this would fucking at least pause to hear out the dude's claims of a trap and see if they are valid. People he came into contact with would join in and shout with him to stop the rest of the group: increasing the volume of noise to stop trekking. Also, didn't the fucking the manga establish the Chief is an avid mountain climber hobbyist and has "climbed this Mount Shirabi before."? How the fuck did the chief an hour or so later not pick up something's wrong, that he might have gone the wrong way?
Dude, if the author has to make the characters dumb-fuck retarded to set them up getting them killed and also to move the story line then I'm dropping this manga. Which is a fucking shame, cause the art is pretty decent and I'm curious whether the killer monkey is actually some sort of monster or a costumed serial killer.
