Samurai Deeper Kyo

is a manga series written and illustrated by Akimine Kamijyo.

Samurai Deeper Kyo was serialized from October 15, 1999 to May 10, 2006 in Kodansha's Weekly Shōnen Magazine, and collected over 38 volumes. The manga was adapted into an animated television series in 2002. The Studio Deen production aired on TV Tokyo from July 2, 2002 until December 23, 2002, for a total of 26 episodes. Both the manga and anime have been licensed in the United States, Canada, and the United Kingdom. The manga was acquired by Tokyopop in 2002. However, by 2009, Kodansha allowed its licensing contracts to expire, preventing Tokyopop from continuing the English version of the series. Samurai Deeper Kyo was shortly thereafter picked up by Del Rey Manga, who have completed the series by releasing volumes 35 and 36 in a single volume and volumes 37 and 38 in a single volume.
