Anime adaptaion

The TV adaptation takes extreme liberties with the plot, and only vaguely follows the plot of the manga. Kyo is an artificial construct, born of Kyoshiro's attempt to purge violence and cruelty from himself i.e. Kyo is the dark half of Kyoshiro's soul in a Mibu-made homunculus . While Kyo is resealed inside Kyoshiro after losing a swordfight to him, the circumstances behind it are different. Kyoshiro confronts Kyo at the Battle of Sekigahara in order to stop his bloody rampage, rather than to protect Sakuya. Apart from these and flashbacks to his time with Muramasa, Akira and Hotaru, the anime provides fewer details of Kyo's past. The character of Yuya is often relegated to a peripheral character, while the role of the kenyou is enhanced.
