This series is essentially the love child between Ouran HighSchool Host Club and Maid-Sama!, but is strangely still refreshing in its own way. For one thing, the artwork and layout is WONDERFULLY EASY TO FOLLOW. You have no idea how much reading comedy manga is a pet peeve, with the excessive overlapping insanity that ensues every other panel. For me, it's okay in small doses (it sort of comes with the territory, to be honest), but it can get really old and really confusing in a matter of minutes. Special A miraculously refrains from too much of that so I'm actually able to follow the plot and comic relief without feeling my head spin. The only downside, as other reviewers have pointed out, is that sometimes the dialogue bubbles can get lost in the midst, but I can forgive that due to the clean, clear-cut layout (again, for a comedy manga).
Secondly, the heroine is an oxymoron and I LOVE that about her. Too often we see either "naive and clumsy" or "badass and independent" but rarely do we get something in-between. Hikari is badass (even as "Eternally Miss Second Place"), but my gods, she's oblivious to ANY signs of romantic affiliations towards her! It becomes almost a running gag in the series, but I found it hilarious. Usually naïveté is found in the cutesy, klutzy heroine (or side character), not in the "fighter," if you will. It gives her some level of three-dimensional characteristic that does NOT rely on tragic backstory. Which is SO REFRESHING, especially for a shoujo manga.
Thirdly, we ALMOST get a "jealous love rival" (Sakura, one of Kei's potential future wives), but instead of dealing with pointless drama, she and Hikari recognize that it's an awkward situation for everyone and become fast friends-- and there's no bitterness or betrayal between them either. I positively LOVED that twist! Nothing drives me more crazy in a love story than the stereotypical jealous bitchy character, who's usually only thrown into a series for drama, or, if we're talking Kitchen Princess, reconciles with the sweet heroine midway through. Special A took that stereotype and "pro-wrestled" it to the ground! Mmm!! LOVE IT!!
And fourthly.... Kei Takishima is NOT the perfect guy he's made out to be (though he's pretty damn close, but let's face it, no manga/anime would be complete without one). He struggles with his genius mind vs his feelings, he sulks and threatens when others are in his way, he teases Hikari mercilessly, and he even has trouble accepting being "friend-zoned." HOWEVER, he also shows his resolve by continually treating Hikari with the respect she deserves (outside of teasing) and being uber-protective of her (which admittedly is ONE major stereotype, but one I can forgive). In some ways, he's a typical love interest, but in others, he steps away from the stereotype. When I first began reading this series, all I could think was "this is Takuma Usui from Maid-Sama!, for gods' sake, you're not even trying!!" But as time went on, I noticed a key difference: Takishima isn't just a badass for the sake of being one, because he literally cannot help it. His photographic memory carries his legacy more than anything else, AND because of that mixed with his heritage, he's under a mountain of pressure from his father's side of the family. He isn't "tragic," per se, just far more relatable than say, Usui, or many other typical shoujo "perfect guy" types.
Of course, all seven of S.A. have their share of quirks and back stories. (I personally find Jun's to the biggest hunk of BS: an "alternative personality" via hypnosis that's NEVER been cured??? REALLY???) Oh, and on that note, it's so relieving to NOT have the main love interests be caught in a love triangle or harem. Hell, the closest existence of a love triangle centers around Akira, Yahiro, and Tadashi, and even THEN, it's resolved with Yahiro finding love elsewhere (won't say who; it's kinda shocking).
I loved all the characters and their developments. My personal favorites are Akira and Finn, though I still root for Hikari and Kei's relationship of course. All in all, this series may not be as clever and satirical as Ouran, but I still loved it. Besides, I prefer Ouran's anime, and I prefer S.A.'s manga, so there you go.
And I think that's enough rambling for one day. ^_^
