Shizuka Nomura
Shizuka Nomura (野村 静香, Nomura Shizuka?) is a 14-year-old girl who able to get around the shyness of Wataru being a motherly figure to him as he teaches her how to play the violin. She seems to be infatuated with Wataru; as a result, she can be jealous of other women in his life and actually sabotages his relation to Mio. Shizuka happens to be one of the few people to know about Kivat, and eventually Tatsulot, though she does not know that Wataru is Kiva, though by the last episode she does. She is also shown to be very adept at drumming.
In the The Queen of the Castle in the Demon World net spin-off movies, Shizuka is the title villain, using her powers to take out both Nago and Jiro for their disrespect towards Wataru before zapping Otoya with her "Shizuka Beam" for being a lousy father. Then enlarging into a giant, she battles Kiva before Wataru wakes up from his dream.
Shizuka Nomura is portrayed by Rina Koike (小池 里奈, Koike Rina?). She previously portrayed the human form of cat Luna in Pretty Guardian Sailor Moon.
