For ages I've been aware of Aria the Animation as one of the so-called greats in the slice-of-life genre of anime. Indeed, I'd even had most of the series (that is, including later seasons) downloaded on an external hard-drive for years, sitting there untouched, just because I kept watching other things. Recently, I've discovered the webstore Right Stuf Anime, which (not to shill the site) has a handful of otherwise out-of-print TOKYOPOP-published manga in stock, including not only the two Aqua manga volumes, but also half of the proper Aria manga series. So I spent a wee bit of money to purchase both volumes of Aqua (volume 1 was clearly a little over-priced for its age).
Anyway, this manga is pretty great, but you have to accept that it takes the concept of "slice-of-life" extremely close to heart - that is, nothing overly dramatic ever happens in this volume. Furthermore, even written lines teetering on overt romanticism are shot down (with fun-poking humor) at main character Akari by her friend Aika, who makes that claim "no sappy lines allowed!" Instead, the manga sticks quite firmly to the idea of relating Akari's time on the planet Aqua (a terraformed Mars) and her time spent training as an Undine (tour guide gondoliers). Actually, that's hardly true, as this volume mostly focuses on goings-on outside the realm of Undine activity, focusing a little more on life on Aqua, the culture of the city of Neo Venezia, and the people Akari meets during her time in the city, all punctuated by little emails summing up each event, framed as a sort of journal for Akari herself. Throughout this volume, Akari meets feline president of the Aria Company of Undines, Aria himself, as well as esteemed Undine Alicia, and fellow apprentice Aika, of rival company Himeya. The only event of any real consequence/gravity is after Aika received a promotion from "apprentice" to "journeyman," followed shortly thereafter by Alicia and Aria taking Akari on what appears to be an aimless journey throughout Aqua but which really turns out to be the exam for Undine promotion.
Akari herself is kind of airheaded, the sort of character one might expect for a slice-of-life story set in a world so different from our own: she needs to be so naive in order to be so impressed with Neo Venezia's way of life, to better reflect the readers' own awe at everything she experiences on planet Aqua. Akari's character fits snugly into a somewhat generic archetype, but it works well for her, and one shouldn't really expect too much from manga anyway - I personally look forward to seeing how certain series reflect certain anime/manga norms. Akari's design is okay, but it's hard to judge too much, since her clothing is the same as Alicia's and basically the same as Aika's. Her personality comes out in her hairstyle, a somewhat brash short cut kept in check by two lightly-childish locks that fall before her ears like overlong sideburns.
Alicia is clearly meant to be the most mature and graceful of the main girls, and suffers the same flaws as any similar character: she has no real personality other than smiling at Akari's naivete and constantly saying "oh, my!" As with many similar characters (Miyuki from Lucky Star, as a somewhat popular example), I still really enjoy/respect the character, but I really cannot expect anything too interesting to come from her existence. Most importantly, she's just cute. It's probably more accurate to use a word like "beautiful," but I guess I'm just "normie" enough to think that is a bit of a stretch w/r/t 2D. Anyway, her figure isn't too different from Akari's, but her posture makes her stand out a bit in contrast. The back of her hair has a twisty look to it, like the "drill" hairstyle commonly seen in the twintails of "ojou" types in other manga, perhaps helping to establish her aura of affluence, but it could just be simply a counterpart to the choppy style of the back of Akari's head.
Aika's just cute as fuck. It seems, despite the details in Akari and Alicia's hair, Aika excels with a more simplistic style of pure black color and thin braids on either side of her head, a hairdo that makes her look explicitly East Asian, with a sense of Chinese ancestry, betraying her very Japanese-sounding name (in Volume 2, she is seen to wear a shirt styled like a cheongsam, to further this motif). The majority of her characterization is based on a) acting as straight-man to Akari's naivete, and sometimes b) fawning over Alicia in a near-yuri-teasing manner. Indeed, her character would suggest Aqua/Aria numbers among the many manga that focus so much on cute girl characters they seem to forget the existence of men (not that this is a bad thing, by any means - I quite love XY-less slice-of-life, preferring, as a man, to maximize the presence of cute 2D girls), if not for the introduction of Akatsuki in Volume 2. Her yuri-adjacent lust for Alicia balances with her tsundere-adjacent friendship with Akari, and these facets of her personality combine with her physical appearance in such a way that speaks directly to my penis (figuratively, of course).
The best stories in this volume are the one with Akari and Aria wandering among the lightly flooded streets of Venezia, and especially the chapter with Akari and Aika tailing Aria into the kingdom of cats, the latter being of quality significant enough to launch this volume (and the manga overall) to the upper echelons of the medium. The chapter with the promotion exam is brilliant, too, but I think I just subjectively prefer those tales which most reject the importance of the Undine element of the plot synopsis. Not that the gondolier thing is bad, and I actually might enjoy an episodic series about Akari and friends giving rides for various colorful Neo Venezia citizens, but Aqua establishes a level of slice-of-life too pure even for something like that, following the life outside of Akari's work, rather than merely using her job as an actual basis for the narrative.
As a last note, I find the designs of the Undine uniforms so ridiculously lewd. Something about how tight the dress is around the waist and torso, contrasting with the billowing skirt and the loose shirt-thing atop the chest. Also the fingerless gloves are kinda nice, particularly when Akari loses one as part of her promotion.
