Template:AllyInfoComplex Rinna Sawagami (沢神 りんな, Sawagami Rinna) is an impatient Electron Physicist who is researching the Roidmudes monsters' powers and abilities. Aside from working on the Special Investigation Unit's mechanical work, she doubles for Shinnosuke when he is out to search for things.
History
Past
Back at a college in America, Rinna met Kisaburo Sasamoto, another Japanese student whom studying abroad with her. The two developed a small relationship until Sasamoto was forced to leave her due to his interest in studies, thus affecting her.
Present
While in the service of the Special Investigation Unit, she invented the cosplay-looking equipment that detects Heavy Acceleration (referred to some as "Heaviness") and seems to have a background with the first Drive, as she was revealed to be the Drive Pit's "mechanic". Her connection with Drive was first shown when she was checking up on the recently repaired Dimension Cab, which was also assumed that she fixed hastily.
Before Shinnosuke revealed to the public that he was Drive, she was among one of the people with prior knowledge of Shinnosuke as Drive, aside from Kiriko and Mr. Belt.
List of Rinna's inventions
- Tridoron: With Mr. Belt's help
- Heavy Acceleration Particle Measuring Device: Used by Shinnosuke and Kiriko to detect Heavy Acceleration particles. So far, only two models existed.
- Handle-Ken
- Door-Ju
- Heavy Acceleration Reducing Machine: Made for Genpachiro to move normally in Heavy Acceleration waves. Later modified it with adding electric-insulation materials after being heavily damaged by the Judge Roidmude.
- Anti-Roidmude Bullets: Bullets specialised to penetrate through a Roidmude's skin.
- Rear Cowl Boots: Kamen Rider Drive Type Speed's boots which she replicated for Kiriko's use to defend herself against the Roidmudes. The boots maximize Kiriko's kicking power to match that of the Rider.
- Shift Deadheat (Incomplete; completed with help from Harley Hendrickson)
- Trailer-Hou
- Pit Crew Shift Cars
- Second Mach Driver Honoh: Created by reverse-engineering from the original belt. Initially used for her to experiment on but would later be given to Chase.

Behind the scenes
Portrayal
Rinna Sawagami is portrayed by Rei Yoshii (吉井 怜, Yoshii Rei).
Notes
- Her creations were sometimes treated as forms of cosplaying, due to her attributing random motives to it. Additionally, she also shows a huge sense of pride when any of her creations aired on televisions.
