|This article is about a/an character in Kamen Rider Blade.|
Shiori Hirose (広瀬 栞 Hirose Shiori) is a twenty-year-old woman, whom is one of the few remaining BOARD members after it was attacked by the released Undead. She helped the Riders by detecting the Undead on her Undead-searching computer. She seems to care for Kazuma very much.
She had experienced in detecting Undead since she worked in BOARD. She also possesses superhuman strength as Shiori is able to lift a refrigerator only with a finger much to both Kazuma and Sakuya's fright. Her father, Yoshito Hirose is the person who was responsible for breaking the Undead's seal in a fit of madness, dying in the process.
- A clip of Shiori retreating from her father while yelling "Stay Back!" in Parting With the Past has become one of the subjects for Ondol-based MADs.
