Anime/Manga Difference

 * The manga explains little about Jaken's past, but the anime shows that Jaken was once a lord among similar demons. During battle with another Yōkai tribe, the enemy leader had Jaken by his neck when Sesshomaru appeared and told the demon to move out of his path. When this was not obeyed, he calmly destroyed the Yōkai with his poison whip. Out of a sense of obligation, Jaken followed Sesshomaru, who allowed him to become a servant if he could use the Staff of Two Heads.
