Double Arts

The world has been decimated by a mysterious plague. There is no permanent cure. Only those resistant to it, called "Sisters", can treat it by absorbing the toxins created by the disease. They may save the person, but this shortens their lifespan drastically -- once they absorb a certain amount, they die.

The story follows one of these Sisters, Elraine, who is coming to the end of her 'career'. After treating a patient, she is hit with the final, terminal stage of the disease and collapses in an alleyway. Just before she hits the ground, she's caught by a mysterious boy... and the symptoms cease. She's still alive. Once he lets go of her hand, though, it starts up again. What is this boy's power?

It turns out that this boy, Kiri, is the one her organization have been looking for -- a truly immune person from which they can derive a cure. Until they reach the headquarters, though, she has to keep a hold of his hand no matter what. Standing in the way of this is their inherent embarrassment at having to do everything together (showering, sleeping, going to the toilet, eating). Oh, and the order of assassins that is targeting Sisters...

A fun series that was tragically Cut Short after laying down the foundations of its main arc plot. What made its cancellation so heartbreaking was the amount of foreshadowing set up and Left Hanging.

Trope examples
"Kiri: Well, I was confident it would work, but I was mostly just going with the flow... Elraine: The flow!? But you said you were sure! Kiri: Right, because that made you agree to do it! Anyway, nothing bad happened, so I guess it's okay... Elraine: No, it's not okay!"
 * The Ace: Kiri Luchile displays some of the Common Mary Sue Traits (superlative art skills and accompanying dexterity, red eyes, unique and mysterious powers) and seems to be a Marty Stu-in-training, but he also displays some humanising character flaws -- most notably.
 * Also, his artistic and creative senses suck.
 * All Your Powers Combined: Kiri's "Flare" power increases the strength of all the people he's in contact with, by the number of people he's in contact with. 2 people = 2 people with double strength, 10 people = 10 with 10 times the strength and so on. The 'something for nothing' nature of this is Lampshaded later on.
 * Anime Hair: Kiri.
 * Always Female: The Sisters and their organization.
 * Complete with an Amazon Brigade for their protection.
 * The Atoner:, who showed up too late to save a dying patient, once, and was so stricken with guilt that She even ignores the advice of an older Sister, who recommends that she retire. Justified, in that
 * Battle Aura: Just once, when the latest "worst ever" villain is gauging Fallan's strength.
 * Battle Couple: Elraine and Kiri, but not through romantic feelings.
 * Betty and Veronica: Subverted, and with great flair.
 * When dark-haired, midriff-baring Sui appears on the scene, shy Ellie immediately assumes she must be Kiri's girlfriend--and Kiri and Sui instantly flinch and burst out laughing, respectively. Turns out they've already given the dating thing a try (or three) and it was a disaster, killing the possibility of a love triangle deader than dead from the get-go.
 * Blood Knight: Sui just loooooves to fight, is obsessed with finding the strongest, and looks and acts like a cross between Tifa and Kenpachi. Except for . "It's like she's really cute but scary at the same time!"
 * Bottle Fairy: Tisera Gordon.
 * Cannot Spit It Out: Kiri and Elle, turned Up to Eleven. Towards the end of the series, it finally dawns on Elle . She proceeds to Good job, sweetie.
 * And Kiri's reaction is to stand there, trying to play it clueless while
 * Can't Live Without You: Elraine can't live without touching Kiri.
 * Cast From Lifespan: The Sisters' healing powers, indirectly but with the exact same effect as the standard form of the trope.
 * Chains of Love: Part of the premise. In a twist, there's nothing physical keeping them together, just a magical problem counteracted by Kiri. If Kiri really wanted to, he could leave at any time, but then Elraine would die and Kiri's just too nice to let that happen.
 * They do tie their hands together when they go to sleep, but that's completely voluntary and prevents accidental separation and death.
 * The Chosen One: Kiri.
 * Cry Cute
 * Cut Short
 * Dance Battler: Elraine and Kiri's "Double Arts" are based on dancing moves.
 * Dandere: Fallan collects the little flags restaurants put on sandwiches and will blather on about them if you remark upon this.
 * Debut Queue
 * Doting Parent: The Luchiles. They extend their affection freely to Ellie, as well.
 * Dynamic Entry
 * Fan Girl: Elraine meets a Sister who says she's her personal hero.
 * Four Races: Unfortunately, it never elaborated on the last two.
 * Beigers are the best at constructing and designing buildings and crafts.
 * Foreshadowing
 * Gentle Giant: Kiri's father, who terrifies Elraine at first glance and proceeds to quietly and completely reverse the impression with his soft-spoken, friendly ways.
 * Healing Hands: The Sisters. Also
 * Hero Secret Service
 * Holding Hands
 * Hotter and Sexier/Stripperiffic: Defied Trope, among others. Specifically, only Sui had rather revealing clothes, but she's a pure brawler. And Stripperiffic as sister Elaine pushed her limit of embarrassment, she dressed like average casual street dancer!
 * Lampshaded by Fallan, outfit that revealing as much skin as possible would be the best battle gear for speed-focused fighter.
 * And Fallan is a fighter dressed in a semi-formal attire.
 * Well, Fallan doesn't need to keep his skin accessible to Kiri at all times. The point was that, if they were separated in a fight, Kiri needed to be able to get in contact with El again ASAP, without wasting time flailing to find a bare patch.
 * Huge Guy, Tiny Girl: Kiri's mother -- shorter than he is. Kiri's father -- has to duck under ceiling beams.
 * I Have the High Ground
 * The Immune: Kiri, and, to a much lesser degree, the Sisters.
 * Improbable Weapon User: Sui uses a folding hula hoop that's made of solid iron. And can also run along walls whilst she's crouching inside it.
 * Indy Ploy: Kiri's first anti-Gazelle strategy was a textbook example, with a nice jaunty lampshade to boot.


 * I Should Write a Book About This: Elraine certainly did.
 * Knife Nut
 * Last-Minute Hookup: Probably due to being cancelled rather than laziness or an inability to handle it, though.
 * Although they still don't quiiite manage to actually hook up, making them possibly the only couple in the history of manga to be Sickeningly Sweethearts, who Cannot Spit It Out, at the same time.
 * Love At First Sight:  His reactions while   is trying to explain, weeks later, that she might, sort of, maybe, kind of have been falling a little bit in love with him for a while now are priceless.
 * Magic A Is Magic A: A possible mistake:
 * Kiri can stop seizures though, and
 * Martyr Without a Cause: to the point where she's almost a Death Seeker. And she does it all with a cheery smile.
 * Martyrdom Culture: The Sisters, to the point where it freaks Kiri out miserably at times. His impassioned rants about this to Elraine have started to draw her back to a more healthy worldview, thank goodness.
 * Meet Cute: Kiri's mother and father, as shown in a side comic; as sweet young things attempting to enroll at a school for tailors, they over- and under-estimated what a "normal" garment size should be and ended up constructing sample garments too big and small to fit anyone but each other. "Excuse me, but would you like this...?"
 * Martial Arts and Crafts: The titular Double Art is a martial arts style made exclusively for El and Kiri, but the series ends before the style could progress past the two
 * My Kung Fu Is Stronger Than Yours
 * No Body Left Behind: When someone dies from the plague,they merely turn invisible and disappear.
 * Power Trio
 * Proud Warrior Race Guy: Sui again.
 * Rapunzel Hair: Sui, once more. She doesn't take it well when a Gazelle assassin cuts off a few pieces of it.
 * Really Gets Around: Though she didn't get up to anything sexual, Sui has dated every guy in her town. Just so she could fight them. She's dated (and dumped) Kiri three times, which is a sore spot for him.
 * According to an official Omake, she did this within the span of three consecutive days, traumatizing poor Kiri's heart to the point where he "swore off love" at the age of fourteen.
 * Complete with a hilarious gender inversion of the stereotypical jilted-woman sulk, as Kiri works out his sorrows at the sewing machine.
 * Right Behind Me: An interesting variation involving an intercom-style telephone and the subject overhearing, then interjecting.
 * She Is Not My Girlfriend: Happens a lot. Elraine's the only one who says it, though.
 * Shout-Out: Not confirmed or anything, but Kiri has a bust of what looks like Andre the Giant in the role of Fezzik. Judge for yourselves, panel 1.
 * Shrouded in Myth: Fallan Denzell.
 * Silly Rabbit, Romance Is for Kids:  drove   to this. He got better, though.
 * Sticks to the Back: Sui's hoop.
 * Trademark Favorite Food: Sui and cherries.
 * Troperiffic: For its meager length, the creator managed to pull it off. A spiky-haired blond boy with mysterious powers, and only he can save the world! His childhood friend likes to fight! The Official Couple must learn to get along! They must get stronger!
 * Twice Shy
 * Wax On, Wax Off: Kiri and Elle are quite bemused during the early stages of their training...
 * World's Strongest Man: Fallan, also an Arrogant Kung Fu Guy.
