an animated youtube series that I can't find the name of

Hi, i know it's an old post
but i keep having this anime/cartoon in my head and still dont manage to find it >n<
i remembered about my post on this site and went on it, hoping someone answered it with something that could help me finding it, but unfortunately not TnT

i will try to resume everything i can remember again, maybe more details will help other people remember it ?


so here is what i remember :
first of all, it was on youtube, im sure about it, it was a serie with a lot of episode, and all the details i will provide comes from different episode but can remember wich one is from wich episode.
like i said in my first post, it started in a high school, if im right, the backgrounds were pretty simple, most of the time white or black.
i remember there was something about a character, dress as a guy but that was apparently a girl, because i remember a character falling on this one, and then a "questionning bubble" above her head with a drawing mentioning that the character had breast or no balls, something like that.
i remember also a scene in some sort of landfill, with a fight in it between two groups of people.
i remember another scene that was in some sort of secret facility ? with two of the main character that where dressed in tight black clothes, like some sort of ninja, maybe latex clothes ? one of the two character was a chubby girl, the other one, im not sure if it was a girl or a guy?
i also remember, like said in my previous post, that there was a lot of scene with kicking in the balls, or with questioning bubble about presence or absence of private parts on someone.
i dont remember any speaking in this cartoon, so i guess it was not dubbed.
i also dont remember seing text bubble, so either it was silent with just something bubbles with drawing in it to question things, or something entirely narrated like that ?

i said in my previous post it was like a paint quality drawings, but by thinking about it more, i think it was not that bad, maybe not a professional drawer, but not someone entirely amateur or drawing on paint.
also there was at least 3 main character ? maybe more, the chubby girl, the girl dressed in boys' school clothes and a girl that i dont remember a lot about.
the characters in the highschool were also all dressed with highschool clothes, a bit like japanese clothes, with skirt for girl and pants for boys.

this one im not sure about, but i kind of remember about a scene in this highschool, when a character who gets hit and goes through or at least smashes into the wall against which he lands

i think i said everything i can remember TnT
i it will help me, or help someone remember the name of that serie, or make someone remember of something too ?
