it's the first manga ive read here so its been years since ive read it but i think it was a horror thrill genre manga definitely japanese and the first chap i think was the mc is kidnapped with his friend and this mc have photograpic memory you know? the thing when he only saw for sec and he already memorised it in then the kidnappers would make those human feed on a long ass tube with something to make them fat like pigs also makes them addicted to the point they cant stop eating and absent minded until the kidnaapers deemed them fat enough and would transport them to this grasshopper like alien so they would eat them.
then the mc would try to escape with his freind who got a bit fat cause he was already eating on the tub when he woke up so he was practically dragging his friend then they meet two other guys i think also kidnapped? or maybe infiltrated all i know is that the black haired with mid length hair is very strong and the other one is a doctor? or maybe scientist?
it was a pretty fucked up type of manga and i cant remember that much but i remember bits where they got into a breading cells with a few girls and many men literally gangbanging those girls they were seems to be also druuged as i remembered when the mc? shoved them kidnappers to one of the cells the men literally grab those kidnappers and also forced them selves into them so yeah thats some of what i remembered i know the ending but i dont wanna spoil anyone if ever they were interested.
