Jin Kamishima is going to go on a journey to the stars with his family, until the rocket is caught in a sudden accident. Only Jin is saved. Several years later, he meets up with a mysterious girl named Toa and finds himself getting involved into the actions of International Solarsystem Development Agency, or ISDA, and their unit called the Dragonauts. These Dragonauts, by forming a bonding with one of the dragon eggs that appeared on Earth in a ceremony called the Resonance, gain both a friend and a pilot to fight against the planet of Thanatos that has mysteriously appeared. Jin and Toa, along with newly born dragon Gio, find themselves involved in this.No, it is NOT affiliated with The World of Darkness, no matter how much the title looks like it.
Tropes in Dragonaut include:
A-Cup Angst — Akira, which comes with being the only "flat" female in a show full of extremely busty ones.
And again, on Mars. This episode takes place only a few miles from the enemy's base—the same base that heroes just escaped from a few moments earlier. Said enemies are also pursuing the heroes. Oh well! Plenty of time to strip and play in the mine shaft sewer!
Boobs of Steel — Garnet, who has the largest chest of the female characters and does most of her fighting in close quarters
The Dragon — Garnet, in that she's Ashim's right hand woman and an actual dragon.
The Dulcinea Effect — In reverse. Toa's known Jin less than a day (and probably talked to him for less than two hours) before she's taking bullets for him, stating her love and making promises to come back for him like she's known him for years.
Eyepatch of Power — Kazuki. His scar-patch only makes it look like he's wearing a thong on his head.
Fanservice - Unusually, this featured cheesecake AND beefcake.
Megumi lampshades this by pointing out how nice it is to be in zero-gravity when you have a rack like hers.
Gainaxing — Impossible to avoid considering the chest size of some of the characters but Episode 5 deserves special mentioning. How Garnet Avoided a Wardrobe Malfunction the for the whole episode is a mystery.
High School AU — The Bonus Episode episode opens on an unusually cast trailer for one of these. Howling Star is a delinquent who falls in love with Toa, and everyone else has random roles. The dragons are somehow still involved.
Karma Houdini — Kazuki's actions - especially when he recklessly opened fire on Jin near the spaceport and damaged the launch equipment while a shuttle containing the rest of his unit was launching — should have gotten him courtmartialed.
Ashim's actions are blatant acts of war (One of which could very well have ended all life on Earth), but nobody makes any real effort to call him on it until the Dragons go to rescue Toa from him, and wreck most of Mars in the process. At which point everyone blames the Dragons rather than the guy who'd been deliberately provoking them for most of the series.
Minor Injury Overreaction — Okay, well he did get blown up in the process, but Kazuki's complaining about what turns out to be a small scar (thanks to the Dragons functioning as pretty good Meat Shields) falls under this.
Ninja Pirate Zombie Robot: This series is an ecchi action sci-fi mecha romance series containing alien robot human-shapeshifting dragons. It also has a bit of Mystery Horror in the start, Slice of Life in the middle and drama at the end. Yup, just like that.
The Ojou — Sieglinde, as Amadeus helpfully reminds you. Constantly.
Which makes it even more heart-wrenching when Akira is killed literally moments after pretty much stating this outright.
Although, in the end their spirits fly away together, smiling with the knowledge that dragons and humans can finally live in peace. The implication seems to be that dragons continue to exist after death.
