I’ll start with the basics.
Sengoku Basara is a series of games much like Dynasty Warriors. You are a singular badass who fights the entire population of a country who’s sole existence in life is to get slaughtered by you. Here is the opening for the latest game.
In addition Basara was made into a 2 season anime composing of 12 episodes. This roughly follows the story of a few characters looking to take down a few other characters who are being a bunch of jerks. Opening for the anime pretty much gives you the idea.
For those of you watching, have watched or are thinking of watching the anime. It is at the same time the manliest and the gayest anime ever. Inuyasha and kagome can only wish to have the passion of Sanada Yukimura and Takeda Shingen
Now that i have spammed you with enough links lets get on to the good stuff.
