Sengoku BASARA, or “The Western Market That Could Have Been”

This is the Great Nippon Spirit.
Many of you anime fans who like to keep current with Japan's anime seasons have probably heard of -- or have been watching -- Sengoku Basara. The show just recently ended its first season, with a second season announced by Production I.G. Studios themselves. The entire cast of characters has a rabid Japanese fanbase, primarily female -- a strange paradox, given that the anime is very blatantly a shounen battle series. The original video game franchise has grown from the first game, Sengoku Basara, to a straight-up sequel, a Guilty Gear-esque 2D fighter developed by ArcSys and Sammy, a PSP brawler that quickly took first place in software sales on its release; and a third title in the works for 2010. The anime brought with it a number of incredible product placement opportunities, from cellphone straps and character novelties to a Pizza Hut endorsement, a special rice label deal, a half-dozen different character-specific flavors of energy drink, and, oh, a stage play. Outside of Japan, however, Sengoku Basara (known to the rest of the world as Devil Kings) has almost never been heard of. What happened?
