Sengoku Strays (戦國ストレイズ?) is a Japanese shōnen manga series by Japanese author Shingo Nanami. The manga is currently being serialized in the Monthly Gangan Wing magazine, and published in Japan by SQUARE ENIX.
Kasane is an average kendo-obsessed girl, when a brush with a mysterious sword sends her back in time to the Sengoku Era. Stuck in an unfamiliar time and place, Kasane also has the poor luck of winding up right in the middle of the turmoil that surrounded Oda Nobunaga's rise to power.
The Sengoku Strays manga series was first serialized in the Japanese shōnen manga magazine Gangan Wing, published by Square Enix. Later, the individual chapters were collected into bound volumes, and three such volumes have been released in Japan. The manga has not been licensed by any company.
