Hime Kino is a 15-year-old girl who attends Hiiragi High School Academy, one of the top schools in the nation, for its voice acting department. Hime's biggest dream is to one day become the voice of a main character in one of the most popular shōjo manga series in Japan, "Mahou Senshi Lovely Blazers". This is difficult to achieve, however, as her voice is not suitable as a professional voice actress, resembling that of a gorilla, thug or even an old hag.
Hime Kino (木野 姫, Kino Hime)
Voiced by: Yuu Asakawa
Hime is the protagonist of the story. Ever since her encounter with the talented voice actress Sakura Aoyama as a child, she has aimed for the goal of being a voice actress herself. She is energetic and determined, but lacks great talent in the subject she wants to perfect the most: voice acting. However, the head teacher of the department saw great hidden talent within her and allowed her to enter the voice acting department despite her underdeveloped voice acting talents. Whenever she introduces herself and attempts to make a cute, girly voice, it turns out to be a very thick, scratchy, middle-aged man voice. Thus, she earns the nickname "Gori-Hime" (roughly, "Gorilla Princess") among her classmates. However, during the 2nd-year vs. bottom 4 dropouts Snow White showdown, Hime portrays an alluring voice for the prince in Snow White, gaining the attention of not only Senri Kudou, but the popular Producer of Idol Unit AQUA named Haruka Yamada. Later on when she is recruited by Producer Yamada, he decides to debut her as a male voice actor. Thus, she leads a double-life under the name Shiro. She belongs to GGC Productions. After finally realising that she is in love with Kudou Senri,Mizuki confess to her. At the end of the series, it is presumed that she is now the voice actress of Lovely Blazer and is married to Kudou Senri.

He shows a cold-hearted attitude toward Hime once he finds out she admires his mother and chooses to ignore her since she doesn't interest him in the least. However, when she portrays the prince's role in Snow White, he helps her out when nobody else is available. He also tries to help her practice her cute voice, but is too distracted by her smile. Even though he portrays a cold exterior, he has a soft spot for small animals. For some reason, this sometimes allows him to soften up around when he occasionally associates Hime with a cat. He is currently active in the anime
