It's a year-end party at Odd Jobs!  The Gintama anime has been through a lot, but Gintoki tells Kagura and Shinpachi to keep it cool.  And then the usual members join in for some real partying... The next morning, Gintoki wakes up to discover that he's made some very bad mistakes. Will Gin-san be able to survive the worst blunder in five years of Gintama!?
