After killing Phibrizzo, a barrier that was holding them in for a thousand of years (or so), has been removed, arranged by Phil (Amelia's father.) Lina gets a letter from someone named Filia, who wants to meet her and offers her money (something Lina can't refuse.)
On the verge on dying, since they have no food on the ship, sea gulls are trying to eat Gourry. Zelgadis figures out that their must be land nearby, and Lina starts to go a lot of wind spells pushing them closer to land.
Lina and the gang starts to put off on going to the Fire Dragon King temple, and decide to check out the current city they are in. Needless to say, Lina and Gourry are checking out the food; Zelgadis is wandering around looking at old temples for a possible cure, causing some ruckess with locals; and Amelia loves the view, so she decides to go up to the highest point of the city, drawing a crowd bellow her.
We find out Valgaav's plan:
Filia gets trialed in a small town after revealing she is a golden dragon. While on trial, Xellos shows up and puts down the dragon race (Xellos is a monster, and Filia is a dragon. Both races hates each other) and sets Filia off. Before anything can get finalized, Filia destroys the town.
Lina and the gange reach an ancient temple which turns out to be an ancient train heading towards the temple of the Fire Dragon Temple. It is powered by magic, so Lina and the rest can't use anything. They are heading nearer and nearer, and they figure to get their magic back, they'd need to find the source that is collecting their magic. Lina decides to cast Dragon Slave against the train, but it didn't work, and they end up only breaking part of the temple.
Lina and the gang are tricked to rebuild the temple they broke. When they are done, they demand answers about the prophecy only to have Almayce show up.
The Elder are sketchy with Lina, trying to save the world, but she gives them and everyone else and sample on what she could do. She uses the Laguna Blade spell, cutting (but not killing) Almayce.
Lina and the gang split in two diffent groups, Xellos, Amelia and Zelgadis in one, while Lina, Gourry and Filia in another. They need to explore two different cities at the same time that seems to be holding magical vessels. The two countries, Alto, and Bantone hate each other, and Lina and the group experiences their daily cannon ball fight against each other. We find out that the King's daughter of Alto, Sera, had befriended and fallen in love with the Queen's son of Bantone, Marco. Both sides, approach each group and they have a plan on stealing the magical vessels. As they do that in the middle of the night, both sides is alerted somehow. They all head for a tiny island that seems to be in the middle of the sea that is blocking them, and each city heads there too. Wait there is even more... creatures show up wanting to take the magical vessels what will Lina and the gang do next?
One of the creatures named Gravos, has the double headed Sword of Light looking weapon. He uses it against Lina and the gang, breaking the island in several pieces, seperating Sera and Marco from them.
Lina and the gang get tricked by Jillas who tellsl them a great power is on top of this funny looking mountain. They get paired by couples, Lina/Zelgadis, Gourry/Amelia, and Filia/Xellos which Filia ultimately refuses. This pairing also upsets Amelia. After some minor fights and tricks by Jillas, Gourry's recklessness causes the mountain to tip over losing his Sword of Light to Jillas.
After 10 minutes of utter nonsense, Jillas runs away to their main base. Once again, they are split it groups, Lina/Gourry, Amelia/Zelgadis, and Filia/Xellos. Amelia/Zelgadis runs into Jillas, and takes the Sword of Light back. Lina/Gourry find Almayce sleeping and wake him up accidentally. We find out his true plans, is not summoning Dark Star, Dark Lord of the Overworld, but wanting to destroy him. Meanwhile with Filia/Xellos, they decide to split ways when hitting a fork in the Labyrinth. Xellos isn't fooled by Filia's way to trick him also, so they both head in the same direction (even though Filia doesn't know it.) Filia hears voices, and is not surprised (yet shocked) to see Xellos trying to cut a deal with Valgaav, who tells him his objective was to bring him to the Monster side. What will Valgaav do?
Valgaav refuses Xellos' offer, and Lina and the gang show up (along with Almayce.) They get into a little fight with Valgaav, and Gourry again loses his sword, but to Valgaav this time. Valgaav reveals to open the gate, you only need two weapons, and hurries to the gate way. Almayce tells everyone without the rest of the weapons, Valgaav will lose control on opening the gate way. He transport them to gate way also, where Valgaav is just about to open it.
After 15 minutes of talk, We get to the climax. As Valgaav open the gate way, Lina decides to use the Giga Slave to stop him, but two figures show up with the other two Sword of Light items, and closes the gate way. As this happens, there is a big explosion, following Lina floating on a debris in the ocean somewhere.
Lina wanders around in several worlds guided by a pig. She finds Zelgadis in costume, and decide to break out of this utter nonsense. She uses a Dragon Slave, breaking a wall, and they both find out they are in an amusement park, theme is where you could travel the world, where Filia is having a good time.
Lina, Filia and Zelgadis decide to ditch the island. They take a small boat, unaware their is a hole in it. Lucky for them a ship pass by, and they get on it before they could go down with the boat. To their luck, the ship is haunted. The Captain, in form of a jar, tells them to get rid of the ghost, and gives them food for it. We find out the Captain had a jar obession and would do anything (even lose crew members) for saving his ""precious"" jars. We find out the ghost was actually a ship mate that is mad at him. He is a ghost because he can't cross over to the other side. Filia reveals she could help and helps him cross over. The Captain then reveals he can finally cross over too. They are left wandering on a piece of wood (or raft). Filia reveals she took a jar that is decaying. They then realize, whatever that was on the ship must of been really old, and would decay too... including the food!
Amelia and Gourry finds out that one of the fish-girl, Lila, is in love with a human, Kerel, when she saved him from a ship wreck. The father of the girl, Honar, objects at first, but their love is stronger. Their is an ancient spell that could change her into human. The only thing is, they need a beautiful young woman to get the stone off a sea creature from. Yes, Gourry is in drag, and they manage to get the jewel of the sea creatures head. When they try to do the spell, it doesn't work. The father feared this might of happen, and reveals they would have to kiss each other to prove their love. This would then transform them oppose each other (she human, he fish) to prove they actually love each other. Of course, they kiss and each other turns shape.
Amelia and Gourry decide to hang out with 3 old people (and their friends) "fighting in the name of Justice" wanting to slay some demons. In the end, the evil trolls (or dwarfs) are actually good, and the demons that Amelia and Gourry had to slay was Lina, Zelgadis and Filia. Lina and Filia got offended when the 3 old people start to call them demons, and started to yell at them. Then the old people fell over, and Lina tried to wake them up (of course they weren't dead.)
Almayce sends out several creatures looking for the last weapon. Unfortunately, they start to destroy towns, and everything in it's way. Lina and the gang decide to stop it, only to have on of Almayce men, Erulogs show up, attacking them. In the midst of the fight, Jilas shows up wanting to kill Lina. He reveals his new weapon, a bomb as powerful as a Dragon Slave, and uses it on the town, but not before Lina and the gang could a barrier around themselves. In the end, the weapon wasn't in the town that they were looking for.
Lina and the gang goes to an old town that was once populated with a lot of people due to it's water and gold source, thinking that the last weapon might be there. Once all the gold (and the water) was gone, people left. Erulogs, one of Almayce's men, shows up and fights them. He end up destroying most of the town, which was sort of a good thing. Underneath the town, water was there hidden there that they were longing for, for many years now.
Lina and the gang reach a temple, which turns out to be an anicent temple for the graves of the Anicent Dragons, that was slaughter by the Golden Dragons. It is sealed off by several magical barriers that Filia could easily break through. Except for one that was sealed by the Anicent Dragons themselves, holding the final weapon. We learn the back story on why the Golden Dragons killed the Anicent Dragons, they feared their power and that's why all (except Valgaav, who escaped) was killed. While this is happening, Xellos has a plan on his own, he decided to befriend Sirus, in an attempt to bring back Dark Star. Almayce tries to talk to Xellos about this, while Lina and the gang fight of Erulogs, except for Filia who is trying to get the the final weapon. To Lina's shock all of the Golden Dragons appear.
Erulogs and Sirus goes on a killing spree, killing on what it looks like to be hundred of Golden Dragons. Lina manages to get away to Filia, seeing if she could get the last item. Filia can't so Lina decides to use the Laguna Blade spell to try and break the barrier. It works, and Lina takes a hold of the cross bow, she fires a shot, displaying it's power. Almayce demands the weapon, but Lina refuses to give it to him. He declarees an all out war on them, but is killed by Erulogs as they come back to the room. Xellos manages to get away and steals the weapon (by appearing in the back of Lina giving her a ""karate chop"" on her next) and runs off with Erulogs and Sirius... what will happen next?
Filia tells the Elder, she is no longer a priestess for their temple and vows to never return to them, as she found out about the truth. Lina and the gang head to the center/the gate what is also called ""Ray of Light"" in hope to stop Xellos, Sirius, and Erulogs. They then run into Jillas, and Filia manages to save him from his own bomb, and he joines forces with them. They then move forward to the Ray of Light stop them.
Sirius and Erulogs decide to join forces with Lina and the rest hoping to kill Dark Star. Dark Star is release but the close the gate way, making his power only half what is truly is. They fight him just a bit only to have him take off, heading towards the Fire Dragon's temple where a voice starts heard, calling the for the Golden Dragons... they realize who it is... it's Valgaav.
Valgaav reveals both the Dark Lord, Dark Star, and the God, Vophied, wanted to purify the world. In doing so, they would recreate everything, meaning killing everyone and starting over. Lina and the gang tries to fight him, but a Dragon Slave would not work. Valgaav tries to talk to them, but moves onto another location.
Filia figures out where Valgaav is going, and transport her last huge power to the Ancient Dragon temple. Erulogs get killed by Valgaav, so Lina decides to do something by combining all of the five weapons (that Dark Star created) and using Filia's Holy Power, and Xellos' Dark power (as well as she casting a spell.)
