Sengoku Basara(戦国BASARA?) is a series of video games developed and published by Capcom, and a bigger media franchise based on it, including two anime series and an animated film. Its story is very loosely based around the many real characters and events of the titular Sengoku era in the history of feudal Japan.
The original game in the series, released in 2005 only for the PS2 as a "crowd-fighting" action game in the vein of Koei's similarly themed Samurai Warriors series. Devil Kings, an English-language version of the game featured an altered gameplay and a completely different, supposedly more western audience-oriented fantasy story with original characters, which was however never used again due to the mostly negative response the localisation received from critics as well as consumers.
Sengoku Basara has several adaptations of the games to different mediums. Notably, two anime series were planned and written by Yasuyuki Muto. The first series, simply titled Sengoku Basara, started broadcast in April 2009. The series' second season, titled Sengoku Basara II, began broadcast in July 2010. Further, a movie adaptation of the series titled Sengoku Basara: The Last Party was released in 2011. All three anime adaptations were licenced and published in the United States by Funimation. A manga adaptation of the second game was created by Yak Haibara. The four volume series, titled Sengoku Basara 2 was published in Japan in 2007 and was later published in the United States in 2012 by UDON under the title Sengoku Basara: Samurai Legends. The title change was due to Sengoku Basara 2 not being released in the United States.  Shimotsuki Kairi also created a more general adaptation in 2005 entitled Sengoku Basara Ranse Ranbu.
Several radio shows have also been produced and have been released on four separate CD volumes. A stage play based on Sengoku Basara 3 was announced on July 17, 2011 and ran from October 1–30, 2011. A live-action television drama titled Sengoku Basara: Moonlight Party premiered on July 12, 2012 on the Mainichi Broadcasting System.
