Dragon Saber/Enemies

Stage 1
BOSS: Akira - This enormous jellyfish-like creature is the first ground-based boss of this game (although his eye reaches right up to Huey and Siria's levels in the air, so he can be classed as an air-based enemy); he attacks by spitting shurikens at the two dragons from his three enormous mouths before opening his singular enormous eye and beginning to extend it randomly around the screen. The aforementioned eye is his only vulnerable point, and while he is extending it around the screen (severely limiting Huey and Siria's mobility while he is doing so) he will continue to spit shurikens from his three aforementioned mouths - and he will also summon an infinite amount of smaller eyeball-like jellyfish to emerge from the water and fly towards Huey and Siria (which can be killed for 100 extra points apiece, but will limit Huey and Siria's mobility even further). But: once you have shot enough Orange or Level-1 flames at his aforementioned enormous singular eye to destroy it, it will explode and you will receive a 2000-point bonus; the explosions will then spread down his extended eyestalk to his body, which will cause each of his three aforementioned enormous mouths to explode as well. Huey and Siria will then proceed to the second stage (but unlike in the original Dragon Spirit, none of the stage endings will segue into the next one's beginning).

Stage 2
In the second stage (which is themed upon lava), Huey and Siria will encounter the Graia from the previous stage, along with five new types of enemies: BOSS: Magma Dragon - Once Huey and Siria have stopped moving forward for a second time in the game this enormous fiery serpent (who is different type of dragon to them) will emerge from the lava whirlpool in the centre of the screen and start flying randomly around it while spitting hundreds of small fireballs from his mouth at them; he looks somewhat like a flaming orange version of both the Radon from Phelios, and the Doragon from Valkyrie no Densetsu (both of which also run on Namco System 2 hardware). His vulnerable spot is his entire body which means that Huey and Siria can spit an Orange (or Level-2 or Level-1) flame at any part of him including his head and it will count as a hit - but as they are doing so in order to weaken him, the fireballs that he is spitting from his mouth at them will increase in size. But once you have shot off enough Orange (or Level-2, or Level-1) flames at any part of his aforementioned body to defeat him it will explode into ten sections (which will not injure Huey and Siria if they fly past them, much like the twenty pieces of Maiku's exploded body from Ordyne), and you'll receive another 2000-point bonus; the aforementioned lava whirlpool in the centre of the screen will then stop rotating in its clockwise direction, and Huey and Siria will then proceed onto their third stage (which is themed upon fossils).

Stage 3
BOSS: Alien King - Once Huey and Siria have stopped moving forward for a third time in game, this enormous spider-like creature will wake up and start flying randomly around the screen while spitting bubbles at them from his mouth; as his name suggests, he looks like a male knock-off of the Alien Queen from Konami Industry Co.'s Aliens, which was released earlier in 1990 and also used a Yamaha YM-2151 FM sound chip for its songs). His only vulnerable spot is his head, and while Huey and Siria are spitting Green (or Orange, or Level-2, or Level-1) flames at it to weaken him, an infinite amount of Medusa will emerge from the five Medusa Nests on the ground and fly up towards them (which as mentioned above can be killed for 50 extra points apiece) - and even though the Medusa Nests themselves can be destroyed once you have dropped enough bombs on them (even though they are not worth any extra points), he will drop a replacement one onto the ground from his tail, which means that you will not be able to escape the combined wrath of five Medusa Nests until you have shot enough Green (or Orange, or Level-2, or Level-1) flames at his head to defeat him (at which point he will explode, and you will receive the third 2000-point bonus; the Medusa Nests and all remaining Medusa will also explode, at this point).

Stage 4
In the fourth stage (it is themed upon renal ground), you will encounter the Tombows, Graia and Tobo from the first stage, along with nine new enemies: BOSS: Jinmenju - Once Huey and Siria have stopped moving forward for fourth time in the game this enormous tree will wake up and grow an extra pair of armlike branches before starting to spit five spreading projectiles from his mouth at you; that aforementioned mouth is his only vulnerable point, and like the Sea Devil from that original Dragon Spirit arcade game, he is only vulnerable when it is open - and while Huey and Siria are spitting Black (or Green, or Orange, or Level-2, or Level-1) flames into it to weaken him, Cape Bats will be appearing on the undersides of his branches, and flying towards them (and they can be killed for 50 extra points apiece). Once you have shot enough Black (or Green, or Orange, or Level-2, or Level-1) flames into his aforementioned mouth while it is open to defeat him, his two extra arm-like branches will turn white and disintegrate, and you'll receive a fourth 2000-point bonus; he will then start shaking back and forth while appearing to break free from his rootings and fly out of the monitor (but he will not cause any further injuries to Huey and Siria as he flies past them). Once he has disappeared out of the monitor, all that will be left of Jinmenju will be his aforementioned rootings - and Huey and Siria will then proceed to the fifth stage (which is themed upon valleys and is the first to feature highspeed flying).
