''Ginga Sengoku Gunyuuden Rai'' also known as ''Galaxy Warring State Chronicles'', ''Galaxy Warrior Rai'' or ''Thunder Jet'' is a space opera the likes of the beloved ''Anime/SpaceBattleshipYamato'' but mixing it with themes that evoke Feudal Japan and China.

After the collapse of the Sacred Galaxy Empire, a battle for control of the Milky Way Constellation breaks out among the War Lords. From the chaos of outerspace emerges a young courageous warrior, "THUNDER JET." Rai Ryuuga is a fearless warrior to his foes but to others, he is a gentle soul, dependable and loyal.

Two powerful forces aspire to reign over the entire Galaxy, Danjo Hiki of the Northern Milky Way and Queen Masamune(Mussamney), ruler of the Southern Region.

Rai Ryuuga sees the ensuing battle and ponders the ultimate goal. Is it power and glory these rulers seek or a peaceful Milky Way under one rule? Rai Ryuuga realizes the importance of this battle and the purpose of his destiny. One day Rai Ryuuga will bring peace to the Milky Way.

!!''Ginga Sengoku Gunyuuden Rai'' provides examples of:

* AntiVillain: 'cept for [[spoiler: Gen-yee and Fomay]], just about everyone Rai faces is this.
* ArtMajorPhysics
* BatmanCanBreatheInSpace : Despite being a space opera, no one wears a space suit, in fact, the concept of space suit is unknown to everyone in this series. On the other hand, the most memorable fights are sword fights with giant stars as backdrop, so a space suit would detract from the intended aesthetics.
* BigBrotherMentor : Rogina to Rai.
* BigOlEyebrows : Rai, to go along with his HotbloodedSideburns and EightiesHair.
* BittersweetEnding : [[spoiler: The Epilogue narrates that despite Rai's efforts to unify the galaxy and all of its kingdoms the task is not complete until 50 years after his last climatic battle - by the son of one of his adversaries]]
* BunnyEarsLawyer : Shishin, Rai's strategist. Mostly in the manga though.
* Myth/ChineseMythology : The Four Warlords are modeled after the four Gods of Heavens, the Tortoise, Phoenix, Dragon, and Tiger
* CoolBigSis : Rogina to Rai, initially.
* CoolShip : Each General has their own CoolShip, but Rai's Kongo takes the cake.
* DragonWithAnAgenda : [[spoiler: Gen-yee and Fomay for Dan-Joe, notable is that each has their own agenda, which includes bringing the other dragon down as well.]]
* DuelToTheDeath : Despite being a space opera, some of the most memorable fights are more often sword fights between generals, most often on top of one of their ships, while engulfed in flames.
* EldritchAbomination : [[spoiler: Gen-yee's true form.]]
* FaceDeathWithDignity : [[spoiler: Rogina, after being defeated by Rai, she gives him some encouraging words, then jumps off her ship and falls onto a star to die a fiery death.]]
* FeudalFuture
* FourIsDeath : The Heavenly Four: Fomay, Rogina, Garer and Gen-yee
* HeroicBSOD : Rai [[spoiler: has to deal with two, when he killed his friend and mentor, Rogina; and when he found out about the death of his wife Simone.]]
* HotBlooded : Rai
* KeepCirculatingTheTapes : This anime is so rare that its virtually [[NoExportForYou impossible to find a subbed episode in English]]; in fact, most of the episodes you might find if you look hard enough are either dubbed in Arabic or in Spanish, subbed in Chinese, -- or really really bad Chinese to English subs.
* MundaneMadeAwesome : Feudal China/Japan wars at a galaxy level using battleships reminiscent of naval destroyers in space! -- Let alone the swordfights with a giant star as a backdrop.
* PettingZooPeople : Garer and his brothers. Should be noted that they're 7 foot tall tigermen.
* RammingAlwaysWorks : Justified in part as there are infantry units inside every ship that will board other enemy ships after impact.
* RecycledInSpace : Feudal China / Japan Wars IN SPACE!!!
* SelfMadeMan : A Military Example, Rai started as an infantry man and by the end of the series he was basically the general and ruler of half of the galaxy.
* SpaceIsAnOcean
* SpaceIsNoisy
* SpaceOpera
* SpannerInTheWorks : Rai.
* StandardStarshipScuffle
* TheStarscream : [[spoiler: Fomay and Gen-yee. They actually try to sabotage each other while trying to advance their own agendas.]]
* TheStrategist : Just about every major General has one. Rai has Shishin, Racko has Cosishoo, Garer has his younger brother Gaten.
* WaveMotionGun : Lampshaded and played straight with Kongo's main cannon -- which fires an artillery shell of huge proportions, and about as destructive as a proper WaveMotionGun.
* WorthyOpponent : [[spoiler: Rai and Rogina.]]
