There's at least one reference to an event in the second season but this reference isn't important and you don't have to watch the second season before watching this.
The story is a parody of attack on titan where all important characters are students or teachers and the titans are bullies who steal the student's food. It is in this setting that the parody recreates many of the scenes from the original anime, though not always in the correct order. A nice detail is that there's also a parody of the original opening which is pretty neat. The parody is pure comedy so if you don't like comedy this isn't worth watching.
The characters are the same as in the original anime but more one-dimensional and with some characteristics changed/taken to the extreme.
The animation is quite alright for a parody and there's nothing wrong with the voice acting. The music seems to be mostly taken from the original anime and simply re-used. This could be bad considering the atmosphere in the parody and the original anime is quite different but it seems to work out alright.
Overall this is a pretty okay parody and worth watching if you were a fan of the original and like the comedy genre.
