This is perhaps one of the darkest and most disturbing anime out there that will certainly leave you with a bitter taste at the end due to its theme. A tragic story about hopelessness, cruelty, pain, bullying, stigma and wasted youth. What it means to be a pig (in other words, the lower classification in the hierarchy of society and school) and what happens when the king of pigs emerges. This movie will leave a very strong impression to you and very possibly it will haunt your thoughts for a few days. Strictly recommended only to mature audience with a strong stomach!
