Gintama: Jump Festa 2005 Special

This special is a set of short comedy stories involving Gintoki and his equally-broke sidekicks Shinpachi and Kagura. One day, Gintoki and his comrades are out viewing the spring flowers when suddenly the Shinsengumi appear, arguing that Gintoki has taken their flower-viewing spot. Gintoki’s team and the Shinsengumi must then battle for the right to sit in that spot by using a violent version of rock paper scissors.
