Melona taunts Leina for being such a weak fighter, and says she only wants to fight decent warriors as she is a participant in the Queen's Blade, a tournament held every four years to decide who is going to be the next Queen. Risty is watching the battle from the sidelines, and just as Melona is about to kill Leina, Risty intervenes and saves her life. Risty tends to Leina until she recovers and takes her as a prisoner back to Vance Castle to recover the bounty on her head.
When Risty arrives at the castle, Claudette appears and arrests Risty for being a thief and imprisons her in the castle's dungeon. However, Risty escapes and steals the Vance Family's heirloom breastplate. She hides in Leina's room and gives Leina the armor, then leaves, encountering Claudette outside and they fight. Meanwhile, Melona appears at Leina's window.
They fight, and Leina defeats Melona by stopping her from shooting acid from her breasts, causing her to explode. Tomoe, a Warrior Priestess, and Shizuka, a Kouma Ninja who has defected, are meditating in the shrine they tend to in Hinomoto.
Tomoe decides she is going to travel to the Continent to compete in the Queen's Blade tournament. During the night, the Kouma Ninja attack the temple. As the battle is being waged, one Kouma Ninja sets off a bomb, destroying much of the temple the priestesses occupy. Trapped in the burning buildings, Tomoe and the other priestesses attempt to escape. However, the Kouma Ninja transform into a giant toad which starts killing the priestesses. Eventually, Tomoe gathers her inner strength and defeats the giant toad. She is then saddened by the loss of her friends, and declares she will avenge them and win the Queen's Blade tournament for them.
The next morning, Tomoe and Shizuka set off across the sea for the mainland. Tomoe and Shizuka arrive on the mainland. Tomoe attempts to blend in by choosing an outfit more fitting for the mainland when she overhears a Queen's Blade battle being undertaken. Leina and Risty reach the entrance to where the Queen's Blade tournament is being held.
Echidna later arrives, charged with returning Leina to Claudette. Echidna paralyzes Leina and Risty with her snake and steals Risty's gold. Leina decides to enter a competition to earn enough money to continue.
The competition involves mud wrestling for a large crowd. In her first match, Leina tries to get close in an attempt to wrestle her opponent, but she keeps dodging Leina's every attempt until Leina attempts led to bits of mud to smear all over her opponent, distracting her long enough for Leina to get behind and toss her down.
Leina is victorious in her first match but only wins 5 gold pieces, not enough to pay their bills, so she has to keep fighting, however this time in an oil match against Echidna. Leina has some doubts but recalls her victory at her previous match and tries to attack first, only to slip miserably on the oil.
Echidna offers to help her up, but tricks Leina into a painful bear hug. Not willing to give up, Leina lifts Echidna, who asks then what. Leina throws her down in a pin, but Echidna uses the oil to slip away and begins to subject Leina in a series of painful holds. She continues to have the upper hand in the battle as Leina has difficulty fighting in the oil, and Echidna chases out all the spectators just as she is about to kill Leina. Meanwhile, Risty breaks into where the winnings are kept and steals them. Echidna's snake Kelta bites Leina on the chest and poisons her, but at the last moment Echidna gives her an anti-venom.
Leina has passed out and when she comes to Risty is gone. Leina heads off to find Risty. Claudette arrives where Leina and Risty were the night before and encounters Echidna, who explains she let Leina go so that Claudette could become countess and hence reward her. Claudette goes to find Leina, and has a flashback to where she rescued Leina as a child.
Meanwhile, Leina eats a poisonous mushroom and Nanael turns up to help her out with some medicine. Leina asks Nanael where Risty is, but she does not know. Claudette arrives and chastises Leina for consorting with thieves and challenges her to a fight to decide who will be the next countess. Tomoe and Shizuka watch the battle from afar and decide Claudette will be victorious.
Claudette forfeits to protect Leina's honor but Leina refuses to accept the forfeit and continues to fight, asking why she has to be the heiress and does not understand why Claudette just accepts it when her father did not like her at all. Claudette says she does it for the Vance Family and attacks Leina, defeating her swiftly with a lightning attack.
The ground gives way and Leina almost falls from the cliff, with Claudette grabbing her hand as she dangles over the edge. Unfortunately, Leina slips from her hand and falls into the ravine below. Leina is missing, swept down the river at the bottom of the ravine, and Echidna goes searching for her. Leina has been enslaved by Menace inside her pyramid. A sandstorm appears and Leina, still possessed, attacks Tomoe and Shizuka.
Nanael appears and turns this into a Queen's Blade round between the possessed Leina and Tomoe. Tomoe and Nanael become trapped in a pyramid with many booby traps. However, Nanael manages to escape by finding a hole in the wall. Just as Tomoe is about to drown in a water trap, Nanael returns to witness Tomoe use her sword to wedge open a brick in the wall and drain the water out, encountering Leina after she escapes. Tomoe manages to break the curse on Leina, causing Menace to attack Tomoe and causing the bridge they are standing on to crumble, with Leina falling into the abyss below.
Shizuka rescues Tomoe from Menace, and explains to Menace how her kingdom failed because of the failure of the princess without realizing Menace was that princess. Menace, through her anger, causes the pyramid to self destruct, and Tomoe, Shizuka and Nanael are washed outside as it is destroyed. Menace states her intention of resurrecting the Kingdom of Amara. Leina recovers outside the pyramid on the edge of a forest, and a Maid of Temptation, Airi, is turning the forest into a swamp. Airi is then attacked by Nowa, Guardian of the Forest.
However, she catches Nowa and steals her life energy, but Leina intervenes and fights Airi. Airi starts draining her life energy, but Leina breaks free and Airi disappears after slashing Leina across the chest. Nowa nurses Leina back to health, introducing her to Combat Instructor Alleyne who heals her wounds, after explaining how the Elves do not normally let humans into the forest. Leina enters the main Elf city and the Elves are not pleased, and confront Nowa about it. Elina goes to search for her sister, while Count Vance holds Claudette in the castle.
Alleyne wanted to compete, but was not allowed by the elders. Leina stops Nowa from leaving the forest and causes her to fight, trying to dissuade her from competing. Nowa convinces Leina to let her compete and the two of them part ways. In Heaven, Nanael is summoned by the Head Angel, who plans to exile her to Hades as she has forced people to fight each other. She threatens to send her to Hades unless she goes to where the Swamp Witch is and find out what she is up to.
Hachiel, a fellow angel, goes with Nanael under the Head Angel's orders to keep her in check, but falls into the swamp and is later rescued by Leina. Meanwhile, Nanael is relaxing in a hot spring by the entrance to Hades when Melona, Menace and Airi show up in a nearby spring.
They all discuss about how they were defeated by Leina, and Nanael passes out from the heat and turns up in the same spring as the other three, where she accidentally tells them she has come to observe the Swamp Witch. Nanael offers to tell them where Leina is in exchange for information about the Swamp Witch.
They tell her that the three of them have been asked to participate in the Queen's Blade. Nanael then tells them the direction to go to find Leina and they run off to find her.
