There were multiple episodes of it, but it was definitely more guro-themed. All I remember is this one kid walks down the wrong path, get confronted by several bullies, who mistake him for somebody else, and ends up stabbing him. The end of the scene shows the camera moving away, showing the kid's guts on the floor. They were shorts from one big episode, but so long time has passed, I completely forgot about the name of this anime. Does the plot sort of remind you of something? Please, I would like to know. This is all I remember from watching it many years ago.
