Hime is the alias of a series of villains in Kamen Rider Hibiki. She is always seen with her partner, Douji, and lower ranking versions of the two appear to have swapped voices when compared to the others.
"Kamen Rider Hibiki
Sidekick, Support or Villain? Villain
Does She Get a Belt? No
Would I Give Someone Else's Belt to Her? No
Is She Dead? She's not a single person, she's a series a people, and so she dies all the time. Although, there are at least two sets of her known to be alive at the season's end."
