The Sket-dan encounter some unexpected guests as the main cast of Gintama shows up in their clubroom unexpectedly. This can only mean one thing: It's crossover time! Can there really be room in the world for 2 different shows based on Shounen Jump manga airing at 6 PM about a trio of misfits who do odd jobs?!
We'll never call you a 
poor man's Gintama again!
¡Nunca volveremos a llamarlos 
copia barata de Gintama!
¡Nunca volveremos a llamaros 
copia barata de Gintama!
Nunca mais vou chamar vocês 
de primo pobre do Gintama!
