To cover some surface points quickly, Ozaki Akira's art is visually pleasing and perfectly suited to the plot. Haru x Kiyo is a genuinely hilarious series, and Ozaki's art and paneling skillfully deliver the jokes.
And now to the main reason I wrote this:
The reason Haru x Kiyo holds a special place in my heart is because it has a solid center.
While I could nitpick and point out a couple of characters (the older brother and the chibi girl, for those who have read it) are drawn out needlessly for drama, I was hardly ever bothered by it because Koharu and Kiyoshiro handled their relationship so well.
To put it simply, Koharu and Kiyoshiro love, respect and trust each other. Which is an easy thing to say, but a much harder thing to stand by in a shoujo series. But Ozaki-sensei does it so skillfully you're left wondering why other series have such a difficult time of it. Not once does one accuse the other of cheating because of being caught in a bad situation, not once does one not apologize when a situation goes awry.
Through every conflict, Koharu and Kiyoshiro treasure each other and that holds the chaotic cast and plot together.
