The following tropes
A Boy and His X: In this case, dragon. Emrys is often reffered to as a 'pet' and 'child's toy' that Bran is too found of to replace with a bigger/stronger/faster etc, breed.
Animal Eyes: Edern has cat-like eyes due to him being Fair Folk.
Anti-Magic: Old people are resistant to magic and the older they are the stronger the resistance. This is because magic is based on 'potential' as in 'potential energy' and younger people have more of it.
Always Chaotic Evil: Downplayed with dragons. They can be tamed for a few years but all of them inevitably go feral. Dylan has been injured because he didn't replace one in time.
Bait and Switch: Nagomi's introduction has her complaining about the raining and walking in the mud and other things that can make one think she's a spoiled noble girl who joined the clergy for some selfish reason. Then her group's porter is injured and without hesitation she kneels in the mud to heal him despite knowing it will be a thankless job and the onlookers will scorn her for her hair color.
Blessed with Suck: If you find you can use every kind of elemental magic with equal skill then congratulations! You're a once-a-generation prodigy who will no doubt become famous! You'll also die before your thirties because the conflicting elements will tear you apart.
Blood Magic: Alluded to in a custom made gaunlet but not seen just yet.
Big Bad: Zigzagged. While Nariakira schemes like a big bad and has the ambitions of a big bad, he only has one scene in the first book.
Dragon Rider: Bran and many others. Dylan is a commander in Dracaland's Dragon Rider division.
Elemental Powers: It's possible for anyone to learn them but every mage has to make due with a 'innate speciality' for one or another. Sato, for instance, is an Ice/water Innate. While she can cast fire magic too it is weaker, less versaile, and more exhausting.
Averted. The closest thing the first book has to ' devious scheme plotted by a villain' is Dylan trying to replace his son's pet dragon with one more suitable for a professional dragon rider. This is something all dragon riders have to do eventually and all of Bran's generation has already done it.
A Qin saboteur is hinting "a cause older than the rebels or the court" but he doesn't appear until midway and isn't seen again for the first book.
Forgets to Eat: Sato cooks dinner for her dad and it often goes cold because he's too busy with an experiment.
For Science!: Sato's dad Shuhan is aware that his research will likely never be published or accepted because of his disgraced family name. He continues to sate his own academic curiousity.
Gender Is No Object: Dracaland army and society, contrasted with strict gender roles in Yamato. E.g. Reeve Gwenllian.
Good Scars, Evil Scars: Dylan, the story's functional hero, has a scar running across his cheek and possibly more around his body.
Gone Horribly Right: Pre-series, mages raised the dead and used them as weapons of war. They were so successfull no one could tell the undead from the truly living. It made everyone paranoid.
Qin was this pre-series but it has since been discovered, exploited, and decayed as a result.
Yamato, more or less, is still this at the start. Only the Bahtaavains know how to cross the Divine Winds and even they can only go to Dejima. Aside from a few Dracaland officers, the rest of the world doesn't know it exists. The main conflict of the series is whether Yamato should stay this or open completely.
Not So Different: Bran sees the Orient and especially Yamato as 'exotic' and 'wonderous' etc while Sato holds the same wonder and awe of the world outside Yamato. For extra points, her fasincation is centered on a freshman textbook from Bran's country college; both of which he found to be stifling and boring.
Puppy-Dog Eyes: Nagomi's father didn't like how his daughter frequently brought 'stays' to their clinic because it was bad for business. She shined her 'doe eyes' on him and he reserved part of the clinic for them.
Red-Headed Stepchild: Nagomi is picked on by almost everyone for being the only red-head in the city.
Samurai: They range from spoiled brats, to a noble-minded girl, to an out-of-work interperter who hangs onto his swords to prove he's not entirely destitute.
Sweet Polly Oliver: Sato is a weird case: She dresses like a boy down to binding her breasts and her dad refers to her as his son but apparently everyone from her students to the local government knows she's a girl.
Scenery Porn: Everything from the college, to the country, to the city, to the warship to the shrine is lavishly described.
Supporting Protagonist: Bran is the one the story follows but after the third chapter or so he's just watching his Dad be awesome.
Deuteragonist: Reducing his role further, he's absent and/or Out of Focus in the latter part of the narrative while Sato and Nagomi share center stage.
