Saikawa Yui is a nationally famous idol on the rise who also happens to be a ridiculously wealthy heiress. As her parents died three years ago, she is now head of a household that possesses, among other things, a sapphire worth upwards of three billion yen.
How she happened to find Kimizuka or know he was tied to a famous detective is unclear (though I’m guessing with her money she can afford all manner of resources) but her mission for him is simple: prevent the theft of the sapphire on the day of her live Tokyo Dome performance.
Nagisa threw Kimizuka for a momentary loop when she declares that she is the legendary detective and he is merely her sidekick, but he isn’t surprised for long. After all, Siesta’s heart is beating in Nagisa’s chest, and Nagisa later mentions that due to her prior poor health she didn’t really take pains to establish a clear identity for herself.
Now Siesta’s heart seems to be pulling her along, and Nagisa seems game to be along for the ride. Nagisa has taken a shine to Kimizuka, and vice versa, and while Kimizuka is concerned that the fact Nagisa wears her new heart on her sleeve could cause problems for her as a detective (who must always follow their heads first), that doesn’t change the fact he’s looking as forward to working with her as she is him.
Despite being packed with just the kind of almost-too-polished witty banter I often enjoy in these kinds of series, this was still the weakest episode of the bunch. It lacked the action and intrigue of the double-length first episode, and lacked much of the emotional resonance of the second. Instead, it’s basically about a case-of-the-week(s) that seems simple on the surface, but it’s complexities remain known only to Kimizuka.
While his claim that Yui-nya is lying should bear intriguing fruit next week, and there were likely a few clues this week that will be referred to when he makes his big deductory speech, the fact is this episode’s true value can’t be fully assessed due to its reliance on the payoff in the next.
Also, the fact Yui is so quick to label Kimizuka a pervert feels both lazy and unnecessary. Even if it’s mostly in jest, it undermines the goodwill built up last week which portrayed Kimizuka as a decent mature fellow. Yui doth protest too much…though maybe that’s the point: she’s trying to deflect his suspicions about what she’s hiding from him and Nagisa with childish insults.
We’ll see … as for my prediction: Yui made the ransom note-like warning that the gem would be stolen, or possibly hired people to steal it.
