Kiriko Shijima

Kiriko Shijima (詩島 霧子) is a member of the Special Investigation Unit and is responsible for all of the technical work. She was the first to know of Shinnosuke being selected as the next Drive and occasionally helps him. She has a younger brother named Go Shijima, who somehow becomes Mach and involved with Roidmudes incidents for some reason.

Kiriko is also the first tester of the complete version of Drive, however she was unable to handle the power, opting her to find the perfect person for the role.

Personality
She is a beautiful, but scary and almost robot-like stoic young woman. She is defined by Shinnosuke Tomari as being like a stalker or a manager, as she is constantly taking notes of Tomari's habits and meticulously counting them, including the number of times his brain enters "top gear". This is probably due to being saved by the original Drive, trying to make Shinnosuke live up to the Kamen Rider name. During her encounter with Roidmude 010 and one of his Roidmude minions, she demonstrates that she is terrified of her existence fading away while being turned into a data (due to her first encounter with that Roidmude) causing her to be traumatized. Thanks to Shinnosuke, she fights back and fully recovers after finding the courage to stand up to the Roidmude.

Although Shinnosuke sees her as being more capable of using Drive's powers, Kiriko admits to him that "she would if she could", while this remains unexplained, she does show a hidden desire to want to be a Kamen Rider, as shown when she used special boots to match the power of a Rider Kick's power, she imitated Shinnosuke's wrist flip and imagined herself in Drive Type Speed, but when asked about this by Shinnosuke and her brother, she denies this.

Global Freeze
Six months before the series, Kiriko was working her job as a traffic signal-woman when the Global Freeze occurred. She was ambushed by Roidmude 010 and nearly turned into data, but was saved by Proto-Drive, the original wielder of the Shift Cars. This cemented her admiration for the Kamen Rider name. Unfortunately, Proto-Drive allegedly lost his life battling the Roidmudes, which severely affected Kiriko.

Present Day
Six months later, when she learns that Shinnosuke is to be the next Drive, she pushes herself to mold him into a worthy successor for the original Drive, explaining the heavy pressure she exerts on him. She is the one who teaches Shinnosuke how to transform, distracting Roidmudes during his first fight to buy him time to do so.

She later surprises Shinnosuke by smiling when Roidmude 029 refers to him as a Kamen Rider, reminding her of the original Drive. His interrogation as to why bears no fruit. Later on, when the Vegas Dream Shift Car returns from investigating the Roidmude that ambushed her six months ago, she becomes irritable, doing her best to try and find the culprit. She is able to find that the women in the art studio were trapped in the paintings, and manages to free Roidmude 084's drawings before needing help from Shinnosuke.

Kiriko takes her duties as Shinnosuke's partner seriously and wants to be considered an equal to his previous partner, Akira Hayase. She intended to accompany him on a hospital visit to Hayase, but because he was in "Top Gear", Shinnosuke was focused on his own purpose and brushed her off without realizing that it would upset her. They later reconcile and go to the hospital together so that Kiriko can meet Hayase for the first time.

When she encounters Roidmude 010 and his subordinate, she tries to fight back against her trauma, but is seemingly overpowered and begins to fade away into data, until Drive saves her.

It is suggested that Kiriko has an unknown connection to Chase. When Kiriko steps in to shield Shinnosuke from an attack by Chase, he finds himself unable to shoot her. During a later fight with Shinnosuke, Chase experiences hallucinations of Kiriko which render him incapable of attacking Shinnosuke further.

The reason that Chase wasn't able to shoot her nor continue his battle with Drive having an illusion of Kiriko because he is actually the warrior who saved her during Global Freeze, Proto-Drive as it was revealed in Episode 14.
