Our dear NEET Hibiki is imprisoned in a special jail in which life is unfair and you have to make your way to the top if you want to survive or at least be respected. In this case, the show provides us a summary of the last 9 episodes to refresh our minds. I consider this episode average because it was just a recap but...was it really necessary to have a recap of this short anime? I don't think so. Anyway, it sums up the story really well and you'll remember some things to follow up the story properly. If you don't like loose ends, watching it is a MUST.Otherwise, just skip this special episode!
