Want crack, action, and/or soap opera plotting? Stop reading this and go look at reviews for, say, Takakura Row, Nitta Youka, or Tohjoh Asami.
Voice or Noise offers none of those things. If you're not inclined to this type of manga you'll find it to be slow, a little confusing, a little boring, and devoid of anything except UST. If you are inclined to this type of manga, you'll find it to be intelligent, gentle, and sweet, with the UST a satisfying instead of irritating element. I found myself landing firmly on the latter side of the fence, and despite its flaws, this title is one of my favorite recent releases.
The text is hard to follow at points; I suspect that the translation is a little obscure, and the flow through the balloons could have been handled better. Whatever the reasons, I had to back up on a regular basis and reread to make sure I was getting it. The other major issue is that, although the mangaka indicated that she would continue it, the story seems to be on hiatus. Which, if you enjoyed this series as much as I did, is a bit frustrating. Vol. 2 ends at a three-year jump, and now I dearly want to know what's going to happen to Shinichiro's and Narusawa's relationship. C'mon, Enjin-sensei--don't leave us hanging!
Bonus points for a contrary, awkward seme; an impetuous, goodhearted uke; and the funniest, most irreverent talking cat you'd ever want to meet.
