-->''In a world where a giant sword stands upon a land full of adventure and magic, a world called Earth Tear. This is the story of heroes who journeyed tirelessly across Earth Tear!''

''Ha-ou Daikei'' or ''Lord of Lords Ryu Knight'' is an anime produced in TheNineties, airing in 52 episodes from 1994-1995. It takes place in the mythical world of Earth Tear where, far off in the distance, a giant sword can be seen thrust into the very land itself. Legend has it that whoever journeys to the Earth Blade will become the greatest warrior alive and one of the many warriors to take up this quest is the young aspiring knight, Adeu the Sonic.

Life is not easy for the idealistic young warrior who, in his very first appearance, gets all of his money suckered out of him by a pair of street urchins. The world is closer to a post-apocalyptic, ''FistOfTheNorthStar''-esque land than the standard fantasy medieval setting in parts, and people are consistently terrorised by outlaws riding powerful mecha called Solids. Fortunately, Adeu has a secret weapon of his own: one of the legendary Ryu, which outclasses any Solid in combat power, the Ryu Knight, Zephyr. With Zephyr at his side Adeu is almost unstoppable but the challenge has only just begun.

Eventually he is joined by Paffy, a princess and an apprentice mage who is on a journey to strengthen her powers. Accompanying her are Sarutobi, a ninja who acts as her bodyguard, and one of her own retainers, a priest named Izumi. Together the four battle against the evil that infests Earth Tear and draw ever closer to their ultimate goal - the Earth Blade itself.

!Here's some tropes from the Ethos of Chivalry!:

* AchillesHeel: Solids, ryus, and dooms require mystical energy called mist surrounding them constantly to absorb and use as fuel; this makes them useless in tight spaces such as caves without mist tanks.
* ActionGirl: Paffy. Katze, [[FauxActionGirl not so much]].
* AmuletOfConcentratedAwesome: The Spirit Stones.
* {{BFS}}: As mentioned, the Earth Blade, which is clearly as tall as a large mountain ''at least''. According to a village elder in the middle of the series, [[spoiler:its actually the sword of Earth Tear's god, embedded in his ''shield'', making that a {{BFS}} of a different variety. Its uncertain to what degree this is true, as whilst its a creation myth, the elder turns out to be a Helldragon, and yet acknowledges the creation myth when he follows up with explaining the origins of the Helldragons]].
* BigGood: White Dragon near the end of the series.
* BlackKnight: Galden
* CallingYourAttacks: Everyone save for Katze and Hittel do this.
* CannonFodder: Standard solids in a nutshell.
* CatchPhrase: Here's one lesson from the Ethos of Chivalry!
* EvilCounterpart: Dark Knight Steru to the Ryu Knight Zephyr.
* EyeScream: Whenever Galden summons Steru, he pulls the Mist Tarot out of the "eye" on his armor and it seems to cause him some degree of pain.
* FighterMageThief:
** Fighters: Adeu, Gratches, Gesshin
** Mages: Paffy, Izumi
** Thieves: Sarutobi, Katze, Hittel
* FiveManBand
** TheHero: Adeu
** TheLancer: Sarutobi
** TheBigGuy: Izumi
** TheSmartGuy: Also Izumi, being the group's GeniusBruiser
** TheChick: Paffy or Katze
* TheGunslinger: Hittel
* HeelFaceTurn: At the very last moment, Galden, and the previously corrupted Steru turns into a KnightInShiningArmor.
* HeroicBSOD: When Paffy realises that the man she was betrothed to has effectively sold her country to the enemy, she almost completely loses her faith in humanity. Fortunately Adeu is able to step in before it goes that far.
** Adeu himself falls victim to one as well.
* IdiotHero: Adeu, so very, very much.
* ImprobableAimingSkills
* ItMayHelpYouOnYourQuest: Ryu Knight Zephyr, although significantly more useful than the typical examples of this trope, was just a card when Adeu got it handed to him. He was quickly disabused of that notion, though.
* KillEmAll: [[spoiler:The last few episodes can be accurately summed up as "in this episode, somebody dies". Except when it's subverted at the very last moment for some BigDamnHeroes action.]]
* KillItWithFire: Paffy's trademark Honoun spell and also her reaction to any [[WhyDidItHaveToBeSnakes slimy or scaly creatures]] the party comes across.
* MagicKnight: Galden, somewhat justified since it is revealed by Idoro that [[spoiler: he is half helldragon.]]
* ManBehindTheMan: Idoro was manipulating Galden the whole time to prepare the way for the real villains of the show.
* MidSeasonUpgrade: Subverted because save for Adeu and his Zephyr everyone gets their upgrades late in the series [[spoiler: especially for poor Sarutobi.]]
* MindControl: Adia attempts this on Galden by using a special ruby on Steru.
* {{Ninja}}: Sarutobi
* OurDragonsAreDifferent: The second half of the series reveals the helldragon tribe, the primary antagonists of the series that are said to have been spawned by their god (Meditto)'s sword and act as alien invaders with highly advanced technology. Later in the series it is revealed that some of them resemble humans to pilot dooms (their HumongousMecha).
* ProudWarriorRaceGuy: Gratches
* RealRobot: Despite the presence of the Ryus (see SuperRobot below), these exist in-universe to a mild degree as 'Solids'. There's a great deal of variants throughout the series, but they do seem to be part of standard militaries, and many of them clearly use mundane weaponry - like guns - over some form of mystical counterpart. Despite this, their power source ''is'' a mystical ether known as 'Mist', same as any Ryu, and any Solid without proper legs lacks clear propulsion - the sphere's they stand on evidently don't spin or anything.
* RidiculouslyCuteCritter: Hagu Hagu, the show's mascot.
* {{Samurai}}: Gesshin
* SuperRobot: The Ryus of course. Aside of being more powerful than any Solid (though this doesn't account for skills of the respective pilots), they're summoned from out of cards, one can cast magic through them, channel the power of the gods, they have higher grade weaponry (such is the implication with Zephyr's sword being required to kill a dragon), can upgrade into various super modes through mystic gems, and are capable of flight without actual propulsion. They also may or may be armours [[spoiler:given to Earth Tear by its creator god]].
* VideoGame/SuperRobotWars: Appears in the Super Robot-only ''[[VideoGame/SuperRobotWarsNEO NEO]]''. Adeu, Paffy and Galden later appear in ''Operation Extend''.
* ShockAndAwe
* SiblingYinYang: Katze is the cowardly, money-grubbing weapons merchant who has a keen eye for details. Hittel is the [[{{Trigun}} Humanoid Typhoon]] in elf form. Together they are one impressive team.
* ToBeAMaster: Adeu's whole reason for travelling.
* TookALevelInBadass: Derringer when Hittel is riding it instead of Katze.
* TheUndead: At one point Idoro summons an army of skeletal warriors and dragons to kidnap a few of the main characters, even her flying fortress is castle support on top of a giant whale skeleton.
* XMeetsY: ''{{Slayers}}'' meets ''PanzerWorldGalient''.
