The OVA is divided into two parts. The one you think it's serious but it's actually troll and the one that is 'ahahaha lol we trolled you'.
First part is amazing. Second part is typical Gintama.
The art in the first part is sublime. Second part is typical Gintama.
The sound in the first part is great (the 5th opening song, Donten). Second part is typical Gintama.
You will enjoy it for sure. We Gintama fans are used to being trolled but we still enjoy this troll things. Gintoki's past is something we all want to know and even though this is fake, it's still great.
The overall is 10 because of the epicness, the war, the troll, the blood, the Zura, the humor, the troll again, the AHAHAHAHA guy, the troll once more, the Takasugi missing his eye, the troll, the mini Gin-san, the troll, the troll, the troll.
