Characters / Dra Koi

The Protagonist

An Ordinary High-School Student living in Japan. Had a close encounter with the Dragon while she rampaged through the city, and has been followed by her ever since. Lives with his mom, who openly lusts for him.


Tropes associated with the protagonist:

The Dragon

A white 'Ether Dragon' who razed the city of Tokyo to the ground, but reverted to the form of a human girl in order to hide from a Dragon Slayer. Fell madly in love with the Protagonist after he struck her Reverse Scale after she tried to eat the protagonist.


Tropes associated the Dragon:

  • Alien Blood: Her blood is gold. And has a corrosive quality that can cause chemical burns on human flesh.
  • Ax-Crazy: She's no sadist, but her Blue and Orange Morality makes her incapable of caring about collateral damage when using her dragon breath for everything from protecting the Protagonist to chasing him through the school.
    • Fridge Horror sets in when you realize the sheer amount of destruction she's caused, and how her body count must in the tens of thousands by the end of the story and how little she cares about it.
  • Bizarre Alien Biology: A 'Reverse Scale' located in her throat that acts as a weak point. Being struck there forces her to change into her humanoid form, or if attacked there by the Dragon Slayer, will kill her. Apparently, it can also be used for Fantastic Arousal.
  • Black Comedy Rape: Her first sexual encounter with the protagonist is like this, with her asking why he doesn't stop her if he doesn't want it.
  • Blue and Orange Morality: Everything from her inability to care about collateral damage to her... Interesting views on love and romance.
  • Cute Little Fangs: Goes with her Hellish Pupils to remind us of the fact that she's not human.
  • Dangerously Short Skirt: It just barely manages to cover her butt.
  • Death Seeker: She believes her relationship with the Protagonist, whom she refers to as 'the hero,' isn't complete until he does the heroic thing and slays the dragon, I.E. killing her. She finally drops this entirely during the Unfaithful Ending.
  • Eldritch Abomination: Her dragon form. It looks more like a mecha version of a dragon, plus it can shapeshift.
  • Everyone Calls Him "Barkeep": She doesn't have a name, and the protagonist just calls her 'that dragon.'
  • Gag Boobs: Openly questions why human males like 'useless bags of fat' during sex with the Protagonist.
  • Glowing Eyes of Doom: Right before using her dragon breath.
  • Hellish Pupils: Reptilian eyes, naturally.
  • I'm a Humanitarian: Apparently, being in her human form doesn't change her preferred diet. And of course, she makes sure to remind the protagonist about this during the oral sex scenes.
  • Interplay of Sex and Violence: If her dialogue during the Final Battle with the Protagonist is to be believed.
  • Karma Houdini: In the Good Ending, she and the protagonist have their Happily Ever After despite her leveling half of Tokyo and hundreds of thousands, if not millions of people.
  • Little Miss Snarker: Counters every single insult from the Protagonist with a truly glorious comeback.
  • Love Redeems: In the Unfaithful Ending.
  • Loveable Sex Maniac: And she has NO problem talking about what she and the protagonist do while in public.
  • Nice Hat: A white beret of sorts with dragons wing designs.
  • Nigh Invulnerable: Because fantasy can only be killed with more fantasy, conventional weapons like guns are a complete No Sell when it comes to her.
  • Our Dragons Are Different: Where to begin? Her Eldritch Abomination appearance as a dragon? The fact that she can turn into a sexy schoolgirl and is in an Interspecies Romance with a human? The fact that modern weaponry doesn't even scratch her?
  • Person of Mass Destruction / One Girl Army: Even after her transformation into a humanoid form, she can still cause catastrophic damage to an entire city just while chasing the protagonist around. Not to mention she tossed around Power Armor wearing JSDF mooks like rag dolls.
  • Pre-Mortem One-Liner: In her humanoid form, her Roar Before Beating is her literally saying the word "roar". This is usually followed by dragon breath and a lot of Stuff Blowing Up.
  • Puny Humans: Being pelted with machine gun fire and missiles gets little more than an annoyed eye roll from her.
  • Roar Before Beating: When she's in her dragon form and she starts roaring, run.
  • She's Got Legs: The CG scenes take every opportunity to remind us of this.
  • Slasher Smile: An 'aggressive, reptilian grin' that unsettles the Protagonist. Even in her human form, she has a cross between this and a Moe Stare right before stuff blows up.
  • Stalker with a Crush: To the protagonist. She is willing to literally destroy an entire building so he can't hide from her. She's seriously can't get much worse without getting into yandere territory.
  • The Tease: She really likes to draw sex out with the protagonist by teasing him. In public, she's not shy at all about what she and the protagonist do, and talks about it in graphic detail even with others present to hear.
  • Redemption Demotion: Possibly, in the above. The Protagonist says that she's the hero's true reward: a princess, instead of the dragon he has to slay. However, considering she still has her Cute Little Fangs and Hellish Pupils, it's possible that she didn't actually Become A Real Girl, and that he really just said that as a way of stating once and for all that he loves her and refuses to kill her, and no dragon or suit of armor will tell him otherwise.
  • What Is This Thing You Call "Love"?: She won't shut up about 'romance.' Dragons view romance in the old definition of the term, like an epic or story. She believes her 'romance' isn't complete with the protagonist until he kills her, but she adopts the more modern definition after the Protagonist convinces her how stupid that is in the Good Ending.
  • Wave Motion Gun: Her Breath Weapon resembles this more than fire.
  • Woobie, Destroyer of Worlds: When asked why she kept trying to kill the Protagonist if she loves him, she responds by saying that is the only way dragons feel able to express themselves to humans. She can't separate the idea of loving someone from hurting or even eating them, while still being normal enough for it to hurt her.
  • You Gotta Have Pink Hair
  • You Sexy Beast: From city-destroying monster to sexy schoolgirl.
  • Zettai Ryouki: Type A.

The General

The Protagonist's mother. She looks like a little kid, but she's Older Than She Looks. She's also a general in the JSDF, and the leader of the anti-fantasy division. She openly lusts after her son, and is incredibly jealous of the Dragon.


Tropes associated with the General:
  • Authority Equals Asskicking: Subverted. She has accessed to Power Armor-wearing mooks, jets, missiles, and the nuclear arsenal... but those are all completely useless against dragons.
  • Berserk Button: The Dragon calling her 'mom' or referring to her as an 'in-law.'
  • Four-Star Badass: Or at least, she would be, if the Dragon and the Dragon Slayer didn't routinely make mincemeat out of the JSDF.
  • Green-Eyed Monster: She's extremely jealous of the Dragon sleeping with her sun.
  • The Gunslinger: She's more than willing to shoot the Dragon herself.
  • Jerkass: Holy crap, is she ever.
  • No Name Given: If she has a name, we never learn it.
  • Older Than She Looks: Admit it, you thought she was a loli.
  • Parental Incest: Completely and utterly shameless about her lust for her son.
  • Parents Walk In at the Worst Time: Hoo, boy... the screen fades to black when she does, but it's safe to assume she was not happy to find her son sleeping with the Dragon under her own roof.
  • Sir Swears-a-Lot: Probably where the Protagonist got it from.
  • Smoking Is Glamorous: Never seen without a cigarette in her mouth.
  • Yandere: Absolutely despises the Dragon for having stolen her son's virginity (which she wanted for herself), and occasionally will shoot her when she makes her angry, despite bullets having no affect on her. It probably doesn't help that the Dragon reminds her of her and the Protagonist's relationship every chance she gets.
  • You Gotta Have Blue Hair

The Dragon Slayer

An emotionless knight in black armor sent to kill the Dragon. Because he is also considered fantasy, conventional weapons don't work on him, either. It's actually not a knight at all, but a knight's armor sent to find the next 'hero' to slay the Dragon; this hero being the Protagonist.


  • Armor of Invincibility: Bullets are totally useless against it, and it can take quite a lot of damage from the Dragon.
  • Black Knight: A textbook example. [[spoiler:Sort of.
  • Blue and Orange Morality: Let's just say he's very, very dedicated to his goal, to the point where collateral damage doesn't matter to him.
  • The Call Knows Where You Live: He's out to kill the Dragon... and if you stop him, you get to do it in his place. Or don't.
  • Captain Ersatz: He looks a lot like Guts with his Berserker Armor activated. But due to the reveal he is more of a Captain Ersatz of the Berserker Armor itself.
  • Dark Is Not Evil: In a Good Is Not Nice way.
  • The Determinator: It will stop at nothing to kill the Dragon, showing zero regard for collateral damage and cutting down anyone and anything it deems to be a hindrance to its mission.
  • The Dreaded: To dragons. Guess why?
  • Empathic Weapon: There's nobody inside the armor. But whoever is deemed worthy of wearing it is patched in to the Hive Mind, which alerts its wearer of incoming damage, and constantly reminds them of their goal... much to the Protagonist's annoyance.
  • Good Is Not Nice: Hell no it's not. He gives zero shits about collateral damage, and anyone who gets in his way is immediately deemed a hostile target and is treated accordingly.
  • Healing Factor: He recovers from damage just as quickly as the dragon does. Later subverted; it's not that he was healing, it's that the armor was auto-repairing. He has no flesh to heal.
  • Hive Mind: His 'personality' is made up of a consensus opinion from every previous hero who used his armor and sword.
  • Knight of Cerebus: His appearances cause an Oh Crap! from both the Dragon and the Protagonist.
  • Laser Sword: The Protagonist describes his sword as a lightsaber.
  • Passing the Torch: To the Protagonist. Part of his goal, along with killing the Dragon, is to find an actual hero worthy of using his gear. The protagonist being willing to Take the Bullet qualified as a heroic deed to him.
  • Person of Mass Destruction: Causes just as much damage to the city as the Dragon herself does.
  • Red Baron: Isn't known by any other name.
  • Red Eyes, Take Warning: He's the closest thing this visual novel has to an antagonist.
  • The Unfettered: God help you if he thinks you're a hindrance to his mission.
  • Well-Intentioned Extremist: Played with. Killing a Dragon rampaging through a town would probably be a good thing in any other case... if that dragon wasn't your girlfriend. His flagrant disregard for collateral damage doesn't help his case.
  • Whole Costume Reference: As mention on Captain Ersatz his Armor has some resemblance to Guts's Berserker Armor.Although he is actually a walking suit of armor.
