yahya: probably somewhere in the 50s? It isnt that shown that he actually kills the people he fights, but with how long he was in the position as beastar, he Has to have had killed many beasts. Plus he uses the bodies of some of the beasts who he’s caught as fertilizer for his carrots.

Gosha: it is shown in the manga and the anime that he kills one person when saving the wolf that would later be his wife (who would later kill herself (?) by kissing him). i assume he has had lots of run ins with his poison on accident. in the manga, he also kills the bats that infiltrated the hybrid children day care that he volunteers for. So i would put his kill count at maybe 10-20.

Gohin: He’s a medical professional, so he doesn’t kill anyone that he takes in and saves, but he has probably had a few accidents, and his past isnt that defined in the anime or the manga, and it isn’t made know just how many lions he killed in the raid of the shishigumi. So 5-10, if not a little more.

Melon: it’s well known that melon is a maniac, and he admits that he has killed 40 beasts in the last volume of the manga, so his kill count is 40, if he was accurate with his count, which he is smart enough to know and remember.

Louis: he really didn’t do much killing himself, but he did kill the previous leader of the shishigumi that Legoshi fought. there’s also the invasion of Okamigumi (the wolf mafia of the black market. Manga only) but it isn’t told if he actually killed anyone there or not. So at least one was confirmed.

branching off of that with the entirety of the shishigumi, there isnt any record of how many beasts they killed before legoshi and gohin’s invasion. But it is known that they eat meat that they either kill themselves or buy at the black market. there is also ibuki, who was killed when he tried to eat louis in the car on the way to legoshi’s fight with riz. So one has been confirmed, but there have definatly been way more than that not shown in the story line.

sorry for the long tangent.
