Hearing all these remarks about Pupa I still wanted to watch it because I never thought it will be so bad. Plus it was only 4 minutes per episode. Never in my life did I feel so distressful while watching an anime.
Story: For 9 episode straight it was just about eating.
Art: It was actually very good that it made me sick.
Sound: Also good that it made me want to throw up when I saw her ate for 9 episode straight.
Plot?!?!?! Not even worth mentioning, but if you must know then watch episode 1, 2, 4, 5, and 7.
Please, if you are planning to watch this I recommend you stop now, but if you must watch it for your own curiosity...Good luck, you will need it.
