You're Under Arrest: Natsumi Tsujimoto, Part 1 of 2

Natsumi is an officer at Bokuto Station.  She can be hot headed and quick to accept a challenge; paradoxically she can also be very laid back often sleeping in and showing up late for work.  She is skilled in hand to hand combat and is unusually strong.  She is also a motorcycle enthusiast and takes up rock climbing with her would be boyfriend Shouji Toukairin.
