Sanada clan
An animated TV special titled aired on March 21, 2014, as part of the series' 10th anniversary. Directed by Kōjin Ochi and animated by TYO Animations with screenplay provided by Yuka Yamada. It features the original cast from the game series. It is based on an early battle in the game, namely, the siege of Ueda castle between the Sanada clan and the Tokugawa clan, featuring Yukimura Sanada and Nobuyuki Sanada as the main characters, and Tadakatsu Honda, Mitsunari Ishida, Kanetsugu Naoe, Kunoichi, Ina, and Ieyasu Tokugawa in supporting roles. The ending of the special, which features cameos by Kagekatsu Uesugi and Nobunaga Oda, teases a full anime adaptation, simply titled "Samurai Warriors", again directed by Kojin Ochi and animated by TYO Animations, which aired between January 11, 2015, and March 29, 2015, for 12 episodes in total. It goes beyond the siege of Ueda castle and covers the entire timeline of the game starting from the siege of Odawara castle, and ending on the Osaka campaign, though it notably focuses on the Sanada clan. More characters are thus featured in the anime, including Hidetada Tokugawa and Hideyori Toyotomi, both of whom received new character designs since both have never been playable in any game of the series.
