I hate how all the buildup from all of Jin's encounters with the beast looking human girls was for a futa joke.
Because yes, that's it the human school arc ends here and there was never any other punchline or acknowledgment to that, only in the omake when Hitomi indirectly acknowledges this girl's similarity to Hyena-kun.
In retrospect I should've know it will all end up being a dick joke, when will I learn.
