The ship has a new name thanks to Parfet… Nirvana, a name that symbolizes Harmony, Stability, and Joy. Dita still has an interest in the ""alien"" Hibiki, who finds the highly energetic girl annoying and would rather spend time trying to find out more about his Vanguard. Meanwhile, Jura schemes to find a way to unite with Hibiki's Vanguard. The Nirvana then comes across a barren desert planet, where they find a artificial structure that is partially buried in the sand. Hibiki isn't happy when the female pilots start to train on the other Vanguards that are left to go down to the planet's surface - especially when they decide to paint them all sorts of ridiculous colors. Despite Hibiki's unhappiness, the Vanguards go down to the surface and find themselves in trouble - but getting out of the situation may be the only way to find out what exactly the mysterious enemy's motivation is.

Hibiki finds himself captured by a ship full of women after being abandoned by his fellow citizens, with the exception of two other unlucky men - Bart Garsus, a cowardly, self-proclaimed ""helmsman"" and Duero, a highly educated student who had become a doctor on a whim to stay alive. Things look pretty dire for the men - but while the pirates are deciding about the fate of their new male prisoners, a mysterious enemy begins an attack on them. Now, in a life or death battle, everyone, even the men, must work to escape this new threat. Bart manages to weasel his way into piloting the ship (even though he has no idea how to), and Duero makes use of his medical skills. A despondent Hibiki, left without anything to contribute, feels that he can do nothing to change his pathetic existence - that is, until the vice-commander gives him some words that he will soon not forget...

Now that things have calmed down relatively, Hibiki now discovers that he still has a major problem - Dita, who still is very interested in him, and whose highly curious actions are starting to get on his nerves. Hibiki having no experience with dealing with women, is at a loss with what to do about the situation, and ends up inadvertantly hurting Dita's feelings. In a rare moment of depression, Dita goes so far as not to talk to Hibiki and state that in battle she won't even combine with his Vandread. The rift may seem impossible to bridge, but Hibiki even goes to Gascogne for advice on what to do. Dita begins to realize that her feelings for Hibiki may go beyond simple curiosity, but hopefully it won't be too late to forgive and forget...

The crew of the Nirvana, minus the men, find themselves at an absolutely crucial moment. They're facing off with an alien flagship, and at the same time, learn some very disturbing details about the aliens' origins. The aliens themselves have some secret weapons, which prove to be a very unpleasant surprise for Meia and her Dread squadrons. Meanwhile, the men free themselves thanks to Rabat, although Rabat's reasons may be far from virtuous. Despite the men's latecoming help, the Dreads are badly beaten and outnumbered, and the Nirvana retreats to the temporary safety of a gas giant. Once there, Hibiki starts working on his attack plan. All he has to do is destroy the enormous enemy force, by himself if he needs to. But with everyone's confidence except Dita's flagging, will he come through?

Hibiki Tokai is a third-class citizen who is a parts mechanic. When he boasts to his co-workers that he can and would steal a Vanguard, which is one of the Empire's elite combat vehicles used for defending themselves against the Mejale, he finds himself boxed in by his own words. In order to silence his doubting co-workers, he has to sneak abord the battleship Ikazuchi and find the Vanguard with the marked part on it that makes it his. However, everything doesn't go as planned, as the Ikazuchi takes off for orbit 2 hours ahead of time with Hibiki stranded on board. As if things couldn't get any worse, the Ikazuchi also comes under attack by a group of fearsome women from Mejale - and not just any Mejale women, but pirates! Found out by the Tarak crew and facing execution for being a stowaway, Hibiki comes face to face with a real live woman in the midst of all the fighting, who he immediately runs away from, despite her overly friendly attitude. But the real threat may not come from th

Things are getting even more hostile on board the Nirvana, as the women vow never to depend on the men again for help. Rabat helpfully returns Hibiki after his ordeal battling against the aliens, but is immediately jailed with the other men for his trouble. Despite Meia and Magno's objections, Barnette and the rest of the women are still determined to fight the Harvest fleet mothership without Hibiki or the other men. With no navigation possible for the Nirvana, and no Vandreads, the women face what seem to be impossible odds, but feel that their own strength of will will make them victorious...

Parfait begins holding a contest to rename the ship, because she feels that the Ikazuchi is a ridiculous and unfashionable name. Meanwhile, Hibiki proves to be a skilled fighter, however he can't seem to ""play well with others"" or be a team player. In order to give him a lesson, Magno tricks him into being reassigned to the supply depot, which is managed by the tough-as-nails, yet highly logical Gascogne. By placing Hibiki in the role of a supply-providing ""stagehand"", Gascogne plans to teach Hibiki the meaning of teamwork, although it may take more than just himself and the Dreads alone to destroy the latest threat from the enemy.

The threat is past, but the new ship is unstable, leaving the crew baffled at how to operate it. One by one, the men are taken from their cells in order to try to help out with the repairs of the ship. However, there may be no time for lounging around, as Dita and Gascogne go missing on a supply and information-gathering mission, and the ship plunges into a nebula and asteroid field that threatens to tear the ship apart. It's left to the crew to once again work together to overcome their difficulties. In the aftermath, the crew discovers that it will take 270 days to get home, as they have been thrown to a remote part of space. With this new knowledge, the men and women realize that working together is a necessity to get themselves home.

Meia is in trouble! Seriously injured in a battle, and having some 'personal issues' as a result, she is facing quite a struggle for her life. The other pilots do not handle the idea that they may have to replace Meia well, and Jura is unable to command the Dreads in her place. Duero, Parfait, and Paiway struggle to save Meia's life as Meia has flashbacks to her turbulent and troubled past. The latest enemy attack may hinder their ability to bring her back from the brink of death, however, and it is left to Hibiki, of all people, to come up with a plan that just might save them all.

It's Christmas time on the Nirvana, which results in confusion for the guys and excitement for the women - even Magno. BC is the only one to stay at her station, and she just might find something strange in the comet that happens to be passing by. Meanwhile, when Hibiki and the other guys find an old video that shows a family celebrating Christmas together, they are startled to see that it shows man and woman living under the same roof! The source of the men's problems is not the contents of the video, however - they've just found out that gift-giving is part of the Christmas custom, and they all have only a few scarce hours before having to do it!

If there's one thing Hibiki is good at, it's playing pack mule for Dita's hairbrained schemes. This time, the two are stealing around the ship, gathering food for some unspecified purpose. Are they surprising the ship with dinner, or just being greedy? Their suspicious actions end up piquing Paiway's curiosity, but she only ends up with hurt feelings after being seemingly brushed off by Dita. Meanwhile, Bart isn't feeling comfortable. No matter what happens, he complains, the crew just doesn't seem to be warming up to him. Fortunately, Duero has some advice prepared that might help - though Bart tends to take things quite literally... Unfortunately, a few misunderstandings, coupled with Paiway's hurt feelings and an impressive chain of assumptions and lies turns the women of the Nirvana hostile towards the men once again. Hibiki escapes in his Vanguard, and the other men are locked in the brig. Alone once again, Hibiki wanders space until he finds a fleet comprised of both men and wome

The crew of the Nirvana come across a planet that is almost completely covered in water. There is one island on the planet, but before they have time to investigate they must face cubed shaped opponents. Jura is as determined as ever to unite with Hibiki, and this is the perfect opportunity for her to do so - although the result may not be what she was necessarily expecting. As Hibiki and Jura crash onto the surface of the planet, the Captain and B.C. go down to investigate, and meet the locals, who seem to be willing to be harvested by the Harvest fleet. Meia and Dita try to desperately hold off the new Harvest fleet ship that is approaching the planet, but it may take Hibiki to motivate an extremely depressed Jura to fight in the new Vandread in order to save everyone.

The crew on the journey towards home comes across a spacebound colony, where they find a monkey who they would later learn is named Utan. They also come across Utan's owner Rabat, who is more then happy to meet the crew. He manages to get onboard the ship and tries to sell them stuff, as any good sales man would. However, Hibiki, BC, and some of the rest of the crew suspect he may be hiding his true motives, and when Rabat tries to force his way into Hibiki's Vanguard to find out the secret of the Vandreads, their fears are realized. Dita is the only thing that stands between Rabat and the Vanguard, but an angry Hibiki may get there in time to defend her and the Vanguard with his bare hands, if he has to.

A very vivid and horrifying nightmare plagues not only Hibiki, but also Dita, Meia, and Jura as well. While they struggle to figure out the meaning of this strange dream, a mysterious pod appears which the Harvest fleet seems to have a vested interest in. Deciding to capture the pod, the Nirvana launches its pilots to retrieve it - but when the events of the nightmare repeat themselves, Hibiki and the others must do whatever they can to make sure that their nightmare doesn't turn into a chilling reality. The contents of the pod, meanwhile, may prove to make things more interesting on the Nirvana than ever.

Every single year, Meia dreads one day - her birthday, when the crew attempts to surprise her with a party. Meia has managed to run away every single year, but this year, Hibiki is here, and he decides to help out the women. Shaking up the plans the women use every year, Hibiki's scouting cuts off every possible escape route for Meia. But when Meia decides to go to Magno with her complaints, Hibiki and the others have to find the perfect thing to keep Meia busy until they can plan the party - even if it happens to be a certain newborn baby.

The Nirvana arrives at yet another planet tampered with by the Harvest fleet, as its inhabitants are unable to survive the air and have all caught a disease that is fatal, with no cure. On a mission of mercy, Duero and the rest of the crew stop at the planet in order to ease people's suffering and help them, and Bart befriends a little girl named Shirley, also bedridden with the disease. However, yet another enemy attack threatens the crew's only attempt to create a clean environment for the inhabitant's babies to be born in, and a reluctant yet determined Bart must leave Shirley to fight for her life while he fights to defend the planet from attack.

The message inside the pod that Misty was frozen in contain something that may be of use to the crew of the Nirvana, but the password proves to be a brick wall that BC can't seem to pass. Even worse is the fact that BC's attempts to crack the password shut the ship down, leaving it completely defenseless to an enemy attempt to tow the Nirvana away to be harvested. The Dreads outside have to stop the enemy, but they have to do it without Dita and Hibiki, who are stuck in a stopped elevator with Ezra, who has just began to go into labor!

The Nirvana comes upon another Mission, though the inhabitants are decidedly hostile and use a law of ""take what you want by force"" in order to survive. Hand to hand combat is the only way to prove the Nirvana crew's strength, and BC, as the highest ranking officer on the away team, chooses to fight in order to prove the Nirvana's good will. The enemy, however, isn't about to stop for a simple fight, and the Mission becomes infested by Harvest fleet units. With energy weapons useless against these new enemies, Barnette's antique gun selection using old fashioned ""bullets"" may be the only thing to keep the Mission from being harvested, although an old acquaintance may make an appearance as well...

Another Harvest fleet mother ship has come to attempt to attack the Nirvana, and the crew, this time, sets out confidently to destroy it using the same methods as before. However, a new form of enemy beats back the attack of the Dreads and Vandreads, and after Jura suffers serious injury, Gascogne is forced to pull rank and push for a retreat, towing an unwilling and furious Barnette from the battlefield. Jura's injury and condition cause Barnette and Hibiki to bristle and Gascogne's seemingly cold and calm attitude, and a heated argument ensues. Hibiki and Barnette find, however, the Gascogne knows much more about the pain of losing someone than anyone else, and that staying calm is the only way to win battles. And Gascogne is willing to teach everyone that lesson, at any cost...

The second attack on the Harvest mother ship has failed, although now Hibiki and the others have a ray of hope in the form of a way to penetrate the mother ship's defenses. Forming a plan around Parfait's limited ability to stop the machine-controlled Harvest fleet, Hibiki and the others launch one last, desperate attack on the mother ship, using Pyoro to upload a virus directly from the mother ship's core. Now the Vandreads must defend the little NAVI robot as he struggles to do his job - but the new enemy form is not far behind...

Things have once again lulled, and the crew now can turn to more important things - such as using cameras to observe the continuing soap opera between Misty, Dita, and Hibiki - a battle the Misty appears to be winning with her knowledge about men and women. A depressed Dita's feelings are hurt, and a guilty Hibiki is left wondering what to do to cheer her up again. Meanwhile, Jura becomes tired of all the beating around the bush and is determined to resolve the rift between Dita and Hibiki once an for all...

The Nirvana nears home, and only has to pass through an incredibly large electromagnetic storm in order to be in their home solar system. However, during yet another battle with the Harvest fleet inside the storm, Hibiki is lost, thrown to parts unknown. As the crew of the Nirvana frantically searches for Hibiki, Hibiki finds himself on a planet with people that have a unique take on destiny and the ""spirits"" that guide them. In order to clear his turbulent mind, Hibiki must now pass the ""trial of himself"" in order to leave - but all the doubts from before may come back to haunt him. Meanwhile, Duero makes an interesting discovery about Hibiki's heritage.

The Nirvana has finally reached its home solar system, but the Harvest fleet's remaining mother ships are not far behind. Despite this, the crew decides to hold a party to celebrate their coming home - that is, until they encounter their last obstacle to their home planets - a Tarak mobile mine field that threatens to destroy them all! With no desire to break through the field because it might slow down the Harvest fleet behind them, the crew of the Nirvana is left to guess the password to call off the system before it destroys them. Unfortunately, only senior officers of Tarak know the password, and time is quickly running out - until the password comes from a most unexpected source...

Having come through the minefield, the entire crew of the Nirvana is promptly captured by both Tarak and Mejale fleets. The men are to be forcefully ""re-educated"" for their desire to be with women, and the women are put on trial and imprisoned. With all seemingly lost, and the Harvest fleet on the way, the Nirvana and its crew are powerless to stop anything. But Hibiki, along with a few other key individuals, may be able to turn the tables and get the Nirvana back from its captors.

With the Nirvana back on track, all that is left now is to defend Tarak and Mejale from harvesting. But the Nirvana and the veteran pirate ship with it might not even be close to being able to fight off three or four motherships. It has come time to unite the two cultures in battle against the one, true enemy that threatens them all, but it may take Hibiki and his newfound knowledge about proving one's own existence to motivate them all to join the final battle against Earth's Harvest fleet.
