Gintama: The Most Important Thing About Anything Is the Beginning, So It's Just Right to Stretch a Little

On a clear spring day, the Yorozuya go out for hanami and encounter the Shinsengumi, who are also there to enjoy the blossoms. A brawl breaks out between the two groups at the viewing site, but since drawing swords in front of civilians is inappropriate, they decide to settle it with rock-paper-scissors. Tae takes down Kondo over a personal grudge; Kagura and Okita immediately start fighting each other; Gintoki and Hijikata get dead drunk competing in a drinking contest... Amidst chaotic rules and unruly atmosphere at the hanami venue, a mysterious giant robot suddenly appears and turns the area into a sea of flames. Inside the robot is Katsura, eager to destroy the Shinsengumi in his fervor for the Joi cause. However, the dependable Hijikata keeps vomiting uncontrollably and is completely useless. Even Gintoki is hopelessly drunk. How will this hanami event end? What outcome awaits their confrontation? This is the legendary Episode 0 of the chaotic Gintama! Please fondly remember those nostalgic times.
