Wisperia

Wisperia is (physiologically, anyhow) a twenty year old Japanese man living in Karasuto. The trusted butler of Akira Noto, he is quite wise despite his youthful appearance. In reality, he is a sentient belt known as the Tamashii Driver; he assists his master in his quest to rid the world of the Grimm by allowing him to transform into Kamen Rider Yurei.

Bio
Like Shiko, Wisperia is a sentient belt capable of assuming a humanoid form. Not much is known about his life before encountering Akira. All we really do know is that upon meeting Akira, Wisperia teamed up with the young man, agreeing to assist him in his fight against the Grimm and becoming his butler in order to avoid suspicion. Wherever Akira goes, Wisperia is sure to follow closely behind.

Personality
Like his master, Wisperia is very straightforward and to the point. He has a very "no nonsense" approach to dealing with things, whether they be as minor as cleaning or performing chores around the house or as major as taking on and defeating the Grimm. He is very loyal to Akira, and the two share a mutual respect and understanding of one-another. Like Shiko, Wisperia is incredibly dedicated to stopping the Grimm; however, the lengths to which he will go to defeat them are far greater, and he sees them all as heartless, soulless monsters with no hope for redemptions, unlike his younger counterpart. Although he and Akira share a close bond, the two aren't exactly what you'd call friends. Their relationship more closely resembles that of a noble and their subordinate. Akira does care for Wisperia, but will set aside his concern in favor of the mission; conversely, Wisperia is willing to set aside his concern for Akira's well-being if it means getting the job done. Like his master, he can be somewhat prideful at times, viewing humans as little more than obstacles that get in the way of cleansing the world of the Grimm. His sense of justice often overrides his desire to protect others, and is of the belief that the ends justify the means.

Trivia

 * His dynamic with Akira parallels the dynamic between Shiko and Takumi in several ways. While Takumi and Shiko's bond is very brotherly, Akira and Wisperia share more of a working relationship. Furthermore, while Takumi and Shiko only target Grimm who actively prey on humans and are willing to spare peaceful Grimm, Akira and Wisperia both harbor a deep hatred from the creatures, and will stop at nothing to eliminate them all, regardless of their intentions. Lastly, Takumi and Shiko welcome the existence of Yurei, while Akira and Wisperia despise the existence of Shinigami and view Takumi as an abomination.
