Kiriko Shijima (詩島 霧子 Shijima Kiriko) is the deuteragonist from Kamen Rider Drive. She is portrayed by Rio Uchida.
Another officer in the Special Investigations Division who tries to keep up a serious exterior, doing her best to not smile while working with mechanical precision, and losing her composure whenever Shinnosuke points out that she has smiled. She is initially the only member of the force who actually knows that Shinnosuke is Kamen Rider Drive and as such often assists him in battles as a sidekick.
She is shown to be very athletic despite her looks and also has the habit of physically dragging Shinnosuke back to work when she finds that he is slacking off, often handcuffing him in the process. Kiriko is later revealed to have had a history with the Kamen Riders since the Global Freeze event when it is revealed that Proto Drive saved her from Roidmude 010. Shinnosuke ultimately helps her overcome her fear of the particular Roidmude when she faces him again after he has become the Paint Roidmude.
When Kiriko learns that Chase is Proto Drive, as part of his explanation that he cannot harm her, she plays a role in helping Chase regain his memories. Kiriko is later revealed to be the daughter of Professor Banno, yet is unaware of their familial ties until Go inadvertently reveals the truth to her after he had been trying to bring him back.
Despite not knowing that Banno is her father, she was aware that her father was an evil man, as he had done something horrible enough to break her mother's heart and then abandon her and their family. As a child, Kiriko never told Go anything about their father, as he was too young to understand, but he comes to realize the truth when he unleashes Banno into the world once more. After the Special Investigations Division is disbanded, Kiriko is transferred to the First Investigation Division with Shinnosuke.
In the film Super Hero Taisen GP: Kamen Rider 3, Kiriko's memories of the proper timeline are instrumental in saving everyone from Shocker. At the end of the film Kamen Rider × Kamen Rider Ghost & Drive: Super Movie War Genesis, Kiriko marries Shinnosuke. Some time in the future, they have a son who they name Eiji.
