Chiharu

Chiharu Kazami (風見 ちはる), simply known as Chiharu (ちはる), is Shiro Kazami's younger sister. Chiharu was a Japanese Idol who was exposed to the nanobots the day her brother became V3. Because she left before Shocker quarantined the ExaStream building, Chiharu was unaware of her being infected until it was too late as her rivals pushed her down some stairs into a live electric circuit, severely disfiguring her face. Unable to cope with it, Chiharu attempted suicide after leaving a note to have her wristwatch sent to her brother. However, Tristar Promotions refused to make her death public, and used the very girls responsible for Chiharu's disfigurement to stand in for her as they release her final song, "Platinum Smile". In order to cover up Chiharu's death, the executives at Tristar Promotions disposed of her body in the city sewers, where the "nano-bots" in Chiharu's body malfunctioned as they revived her into a sub-human monstrosity.

The song "Platinum Smile" soon after became a thing of urban legend, as Chiharu's "ghost" brutally murders those who listen to it, as well as those were covering up her demise. In the end, Kazami faces the wretched beast that was once his sister, and in an emotional climax, kills her. Chiharu seemed to finally be at rest. However, it seems that the curse of "Platinum Smile" did not die with Chiharu, as her "ghost" appears again, hate-filled and embarking on a bizarre murder spree.
