The series was adapted into Sunrise’s original video animation and was featured at Jump Festa 2006 Anime Tour in 2005. This release also caught the attention of many fans, which prompted a complete 367-episode anime television series with twenty-two reported filler episodes.
In an alternate reality, the Edo period is suddenly interrupted by aliens that came to conquer Earth. Humans were no match for these invaders and they quickly surrendered out of fear. The samurai’s swords are confiscated and Japan falls under a puppet government led by those who allowed it all to happen.
