Last week saw the Adventure Club tackle discovering another piece of the Nanana Collection, only to find that it had already been switched out for a mere stuffed toy. But who would do such a thing?
Perhaps unsurprisingly, the answer is that Yuugo is exactly the kind of person who would do such a thing, and indeed that's exactly what he did do, sneaking in to take the treasure before his "sister" Yukihime could get her hands on it. This devilish deed is quickly unmasked by Tensai... because she happened to walk into the apartment just as he was confessing it to Nanana. Yuugo may have won the day, but something is still bugging him, and it's Yukihime at the centre of his concerns.
In short, he really wants to reconcile with her after clearly angering her with his decision to leave Matsuri, and the artifact in his possession makes for some perfect collateral as part of a midnight rendezvous where he offers up a simple wager - if he can land a single blow on Yukihime she'll have to apologise, whereas if she wins she gets the treasure. The trouble is, Yuugo also knows exactly how this part of the Nanana Collection operates, and uses it to gain the upper hand in this fight, in turn revealing a less than pleasant side to his personality before Yukihime's tears leads to a more considered discussion and something of a reconciliation, even if neither individual is willing to move from their current path. With that done and dusted, everyone watches Star Driver, which automatically makes this a terrible episode.
Hyperbole aside (but seriously, Star Driver?!), this was a bit of a weak episode of Nanana's Buried Treasure. I still enjoy how I'm surprised every time Yuugo screws somebody else over even though I know his character by now, but his relationship with Yukihime doesn't really have enough punch to command an episode all of its own, and although it was slickly presented (this show still produces some great fight scenes) there just wasn't anything that resonated with me, or entertained me particularly for that matter. Hopefully things will improve again now that this element of the show has been at least partially dealt with, which should make for some more engaging fare ahead with any luck.
