Dra+Koi is a very short visual novel by Nitroplus about a dragon that attacks a city, gets knocked down by a mysterious dragonslayer and turns herself into a human in order to recover. She comes across the hero of the story and attempts to eat him, but he fends her off and escapes homeward. The next day, she transfers into his class and declares her love for him, chases him down and forces him into a relationship.Dra+Koi is a visual novel with a very silly atmosphere (most of the time) and an odd fondness for metafiction. The cast is very small, the story is short and is at least as interested in talking about stories as it is about the characters, all of whom go unnamed.This visual novel provides examples of:
Blue and Orange Morality: The hero repeatedly notes that, for all that they have a weird but semi-functional relationship, the way dragons think is just off compared to the way humans do.
Breath Weapon: Naturally, a dragon has breath attacks, but she still launches them in human form, at which point her eyes glow and she grows fangs.
Curb-Stomp Battle: The dragon stomps all over mundane weaponry. The dragonslayer stomps all over her in turn.
Cute Little Fangs: The dragon in her human form, so long as she's not fire beams. Eventually, her beam firing form also has mere Cute Little Fangs rather than the massive set of teeth she showed before.
The Dragonslayer: A knight clad in black shows up to fight the dragon because that's what it does. It's actually just the hero's armor. The protagonist is the dragonslayer.
Empathic Weapon / Evil Weapon: The black armor. Just wearing it causes the hero to experience a periodic compulsion to Slay the dragon. It's implied that the armor is animated by the souls of previous dragon slayers, who periodically vote on its course of action.
Fantastically Indifferent: When the dragon shows up in the protagonist's class and begins firing beams, nobody really cares. Justified, in that this sort of thing happens about once a year, so a dragon entering a school may not be all that impossible.
Freud Was Right: When the hero fights the dragon, she describes the act of plunging his hard, powerful sword deep into her quivering flesh in even less subtle terms than those.
Gag Series: The story starts out looking serious: A dragon attacks a city and is intercepted by a badass knight in black armor. Then the dragon becomes infatuated with a student and runs around blowing up the school before catching and raping him, at which point it becomes a romantic comedy. Guys in powered armored suits join the family at breakfast.
Genre Savvy: The protagonist is pretty aware of how things go in stories.
"I'm not some hero, I'm just a kid. There's no magical plot device that will come save me."
He also reflects that normally he'd probably hit her boobs on accident and romantic comedy ensues, but instead tears a hole through her throat. It turns out that this is actually pretty much exactly what he did: the dragon couldn't care less about her breasts, but the scale he touched on her neck is special.
Leitmotif: The dragon slayer's is a wicked metal piece that evokes menace. The protagonist's mother gets one that seems to be a military chant of moe items, like meganekko, tsundere and goth loli. Moe, moe, moe moe moe!
Love at First Punch: The dragon falls for the protagonist when he lands a blow on her 'reverse scale.'
Mad Love: The dragon follows the protagonist around declaring her love before trapping him on the roof of the school and more or less raping him. An uneasy relationship starts up after that. It's implied that all dragon slayers fall in love with the dragons they are destined to kill.
Mad Scientist: The first dragon was beaten when a mad scientist invented an ether destroying device. To fulfill the Romance, he then destroyed it and committed suicide, turning it into Fantasy.
Magical Eye: Dragon eyes are enchanting. Not really, probably. He just fell in love with her on his own.
Meta Fiction: Dragons are always dead by the end of the story, wounds aren't fatal until the story says that they're fatal and only a suitably fitting method can beat a fantasy threat. Dragons attack humans because that's just what dragons do. Heroes destroy dragons because that's what they do. Then the story is complete. Or rather, the romance.
Mood Whiplash: The story is very fast paced and will instantly switch from dates to fights to the death to breakfast scenes.
Morphic Resonance: The dragon keeps her eyes, teeth, and reverse scale in her human form.
Multiple Endings: There are four endings: Two of them bad ends acquired before the climax, one is the good end and finally there's one that's also a bad end, but still completes the story as fully as the good end does.
At the end, if you choose Faithful, the hero slays the dragon without telling her he loved her. The story reveals that the mad dragon's fall was because of love. You're being faithful to the story, not the girl. You also get this ending if you protect her both times, but don't go on the date with her.
If you instead choose Unfaithful the protagonist says that this whole thing is stupid, attacks her 'reverse scale' like before, but this time he turns her into the hero's reward: A princess. You're being unfaithful to the story, not the girl.
If you don't protect her the first time, the dragonslayer simply kills her.
If you refuse to attack the armor and save the dragon after protecting her the first time, the armor declares the protagonist unfit to be the hero, kills him and goes to find a new hero.
Mundane Fantastic: "Oh, another dragon showed up huh? What a pain. I hope the stupid SDF takes care of this quickly."
Nameless Narrative: Nobody in the story gets a name. There's the protagonist, the dragon, the dragon slayer, the protagonist's mother and then minor things like the guys in armor.
Nigh Invulnerable: Only Fantasy can defeat Fantasy, so normal weaponry doesn't affect the dragon.
New Transfer Student: The dragon enters the protagonist's class apparently just to fulfill the cliché.
Older than They Look: The protagonist's mother is an adult woman that looks younger than her son apart from her slouch and smoking.
Only Sane Man: The protagonist is the only normal person in the cast. His mother lusts for him, his classmates are stereotypical to the point of being insane, the dragon is a dragon and thinks differently from normal humans, and the soldiers join them at breakfast in their Powered Armor for some reason.
Our Dragons Are Different: Dragons are nigh invulnerable and capable of destroying a city on their own in moments. That's because only Fantasy can defeat a Fantasy, so when a Hero shows up they're guaranteed to lose.
Parents Walk In at the Worst Time: The mother walks in on the pair having sex the second time. As well as the aftermath of the first time, to say that the mother was angry would be an understatement.
Powered Armor: The JSDF has some suits, but the technology's still rather primitive, and they are frequenly derisively referred to as "metal gorillas." The dragon slayer's armor, on the other hand, is much more advanced.
Demonbane is the kind of fantasy that beats a dragon.
Sir Swears-a-Lot: The protagonist was translated as being rather foul mouthed in order to get across his aggressive attitude.
Slasher Smile: The dragon's main smile is a grin that the protagonist really doesn't like. It's aggressive and reptilian looking.
Sleep Mode Size: The dragon turns herself into a human at the beginning to regain her power.
Stalker with a Crush: The dragon follows the protagonist every, enters his school and even moves into his house. Who's going to stop her? This is part and parcel of the natural all urge dragons feel to connect, and they cannot separate the idea of loving someone from wanting to either kill or devour them.
Standard Hero Reward: Discussed. The hero is supposed to slay the dragon and then get his princess as a reward. In the good ending, the protagonist decides to turn the dragon into the princess and end the story like that instead.
Technicolor Eyes: The protagonist and his mother have purple eyes. The dragon's eyes are a bright turquoise color.
Tsundere: The protagonist protests the dragon's actions a lot, but he seems fond of her in his own way and doesn't seem to like the idea of fighting her to the death.
Urban Fantasy: The story takes place in a city that is attacked by dragons about once a year.
Would Hit a Girl: The protagonist gets in a fight with the dragon at the beginning and blows a hole in her neck to end the fight. She shows up the next day anyway.
You Gotta Have Blue Hair: The protagonist's hair is a whitish shade and the dragon has pink hair. His MOTHER, however, does have blue hair.
