Jaken
A yōkai who is Sesshōmaru's servant: not especially powerful but extremely loyal, he is usually a comical character. Sesshōmaru typically responds to Jaken's failures or more annoying behavior with a sound beating, but Jaken believes this is Sesshomaru's right and never wavers in his loyalty. Jaken started following him in the first place after being captivated by his power and majesty when he slayed a threatening demon, saving Jaken's life (this was incidental; Sesshomaru killed the demon simply because it was in his way. Note: these events were related ONLY in the anime). ("Jaken" means "meanness" or "unkindness".)
