Ichitaka, our protagonist, managed to move from annoying jerk to mildy sympathetic lead, even if his unwillingness to just tell Iori that he likes her is tiresome. (Not like I was any better in high school, so who am I to talk? ) Iori, his love interest, needs some time and work, however. She's the typical manga high school sweetie, kind-hearted, doe-eyed, but lacking in any real defining traits.
The third piece of our love triangle, Ichitaka's former best friend from elementary school, Itsuki (back from the USA and all grown up into a perky young woman in her own right), is a more compelling character at this point. She's fiesty, to the point, and willing to put Ichitaka in his place when he's being a total jerk (which is often). Too bad that she spends most of vol. 3 lurking in the background, coming across Ichitaka when he's with Iori, at which point Itsuki always slinks away with her feelings hurt. She's supposed to be a lead character, but she's largely wallpaper in the this book. With Ichitaka's best guy friend, Teratani, taking a backseat role in these books, Itsuki is the voice of reason, so a reduced role is not a good thing.
Book Three was also too heavy on the emotional drama between Iori and Ichitaka. Itsuki and Teratani are required characters, as without them, NOTHING gets done or said. Iori and Ichitaka can spend an entire book together and do nothing but talk around their feelings,which is cute for a while, but the series is nearly 600 pages old already. Fortunately, Ichitaka does show signs of breaking out of his shell, by asking Iori out to dinner at the end of v.3, but I have a feeling that we'll quickly go back to the usual misunderstood meanings and fear of expressing feelings.
For all of the story's faults, I have no issue with Katsura's art. His clean lines and dynamic action remind me of American comics moreso than most other manga that I've read, although his characters do retain a deliciously Japanese sense of exaggeration and cartoonish anatomy when emoting. And his girls (and guys, too, I guess) are undeniably adorable!
