Rinna Sawagami

Rinna Sawagami (沢神 りんな) 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
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.

Aside from Kiriko and Mr. Belt, she is among one of the people with knowledge of Shinnosuke as Drive.
