Just a flashback episode of gintama-most of it is reused and thus its one of the lowest rating I've given for a gintama special...think those episodes that happen at the end of every season where all the main characters gather around and talk about how the last season went...However its still gintama and I need to watch everything that has to do with one of my favorite series. Its kinda cool watching the voice actors preform their bits live...some of the VA's match their characters others are surprising. I would recommend if your a hardcore fan of gintama otherwise its your choice whether you want tobother with it.
