She uses the wrecked motorbike's engine, modifying the car to make its operation follow closely to that of a motorbike. This car is then thoroughly renovated and heavily modified by Miyuki into a patrol car.

She is subsequently tricked into buying a Subaru R-2, which is in a near-non-functioning state. When off-duty, she operates a Yamaha RZV motorcycle until it is damaged beyond repair during later part of the first season. It is prominently labeled 'NATSUMI' (in the Nihon-shiki transliteration system) before her first day at Bokuto at the beginning of the first anime, later re-colored and re-labeled 'POLICE' in the later appearances and on the Bandai Model kit of the Honda Today. She keeps a mini-moped, a Honda Motocompo (JR-2) in Miyuki's Honda Today squad car and uses it when a flanking strategy is required. Despite having many bad habits, she is a very capable police officer and does her job seriously when needed. Natsumi has a prodigious appetite for food and alcohol and has been known to show up at work with a hangover. She often demonstrates superhuman strength second only to Shōji Tōkairin and is a motorcycle enthusiast, capable of high-risk maneuvers on both bikes and mopeds.

She is very outgoing as well as very laid back. Natsumi is an officer stationed at the fictional Bokuto Station in Tokyo' Sumida Ward. Tamara Burnham Mercer (English) Natsumi Tsujimoto ( 辻本夏実, Tsujimoto Natsumi) is the protagonist of the You're Under Arrest.
