Kappa

Kappa, or Kawako, is a type of aquatic yōkai or water deity that inhabits the rivers in rural Japan.

In the series they are small and weak green-skinned yōkai with a goblin-like appearance and don't seem to resemble the traditional aquatic Kappa from the myths. Jaken, a recurring character in the series and Sesshōmaru's servant is a Kappa and was once the leader of a large group of them that once controlled the plains of Musashi and were at war with Bikuni, the leader of the demons who controlled the eastern mountains. When Bikuni attempted to kill Jaken, he was unintentionally saved by Sesshōmaru, Jaken then left his Kappa subordinates and swore his loyalty to Sesshōmaru. In Episode 129 of the anime, a more traditional looking Kappa, said to be a descendant of the legendary Sagojō from Journey to the West, appears as a minor antagonist and a servant of Chokyukai and is helping him find a bride. His incredibly different appearance from the other goblin-like Kappas seen is never explained, although it may be due to him originating from the "continent" or it may just be an anime inconsistency.
