regarding the best long running shounen, sry, but there is still One Piece
This was a fantastic and poignant ending, I honestly didn't care much for the action even tho I'm sure that it's going to be hype in the anime.
The interactions and the individual character epilogue with gags and the usual randomness on the other hand were immensely powerful. They had all what made Gintama so great, a more fitting conclusion wouldn't have been possible. I really took my time to go through each panel to savour the final words and the beautiful pictures. I've been following Gintama merely for about 2 years, but I still grew extremely attached towards this endearing cast. I guess I have to give credit where credit is due and say this is probably the shounen with the strongest characters. They were colorful, I could relate to them, they made me laugh, got me excited and brought me to tears, thank you so much for creating them Sorachi-sensei.
