-Natsumi's late for work again...Woah, who's that in the Mercedes & why is she smiling at me?
-A giant spider & a schoolgirl? This might be one of Natsumi's most creative excuses yet!
Wait a minute...That girl in the Mercedes! Who is she & why am I teaming up with her?
-Meet Yuka Hasumi, an up-and-coming character actress who's starring in a new TV crime drama soon & she's modelling her character after you, Natsumi-That's why she's teaming up with you for a while (And she has fans in the traffic section as well).
-No Miyuki so Natsumi has to drive the patrol car since Yuka is a civilian...No problem since Natsumi has her auto driver's license, right?

Just remember-"D" is for drive & "R" is for reverse (An automatic & not a 5-speed?).
-So Yuka's not spoiled or egotisical as you thought, eh Natsumi? She also wants her role on the TV drama to be as realistic as possible which is why Yuka's doing this-Spending time with Natsumi on patrol will prepare her more than just reading a script & imagining the role. Anyway, you can count on Natsumi's help to get you ready, Yuka!
-Yes Yuka, this is what traffic cops REALLY do-No snipers, robbers & the like! I don't think that you have to match Natsumi in eating, though.
-Late again but Yuka's on time! Want them to trade places, Chief?
Later on (With Miyuki's help) some training on the day-to day stuff like writing citations, directing traffic, etc...But Yuka seems disappointed somehow. What was she expecting?
-On patrol now...Yuka asks Natsumi to drop her off so that she can go to the criminal investigation section but then a black Honda sedan with another police officer pulls up beside their car. An undercover unit, perhaps? After he leaves the "officer" calls Natsumi on the radio & taunts her & Yuka, saying Natsumi can't tell the difference with a fake cop (Meaning Yuka). He's the real fake police officer-After him!
-This guy's done his homework...With Natsumi & Yuka in pursuit he takes the on ramp onto the Expressway, knowing that traffic cops have no jurisdiction there unless they have permission but Natsuni & Yuka go after him anyway, much to the chagrin of the Expressway Patrol! And on top of that, the fake cop gets away!
-Getting reprimanded by the Chief was bad enough but Natsumi & Yuka also find out that the fake officer posted a photo of them on a police fanatics' online forum with more insults for them. Yuka's manager isn't too happy about this either & takes Yuka with her!
-Time to work on the apology letter...Yuka? So you want to go after the fake officer too & restore your honor as an actress, eh?
Unfortunately, the Chief tells Natsumi to stay out of it & let Detective Tokuno & Investigations handle it. Argh!
-Wait a minute...What's that on your desk, Natsumi? A complete file on the fake officer?
Miyuki, you're the best!
-According to his posts the fake officer knows all about police regulations & hierarchy. Yuka may be on to something though-The fake officer actually believes that he's a real police officer so it should be easy to lure him out...
-What, a second fake officer & he's copycatting me? I'll show him! Only thing is that the second fake officer is actually Ken & you just fell into the trap, bucko!
-The Expressway again? Do you really think that'll stop Miyuki, Natsumi, Yuka & Ken from pursuing you? Nitro on!
-They cut him off but the fake officer won't stop! Yuka, get out of the way!
Oh no, he hit her! Or did he?

Don't mess with an actress who specializes in action sequences!
They got the perp but more apology letters all around, including one from Yuka (Who's also grateful to Miuyki & Natsumi for helping her prepare for her TV role).
-Some days later, the traffic section gets to watch the premiere episode of Yuka's new show,
"Special Attack Detective X". The helicopter & tank chases do make it exciting, don't they? I think Yuka passed the test for her new show, don't you?
Next time-File 14, "C'est si Bon. Wavering Love"
