Season 1

Reina is walking outside of town when she encounters Melona, and tells her she is going to defeat her for attacking travellers. Melona taunts Reina for being such a weak fighter, and says she only wants to fight decent warriors as she is a participant in Queen's Blade, a tournament held every four years to decide who is going to be the next Queen.

Tomoe, a Warrior Priestess, and Shizuka, a Demon Priestess who has defected are meditating in the shrine they tend to. Tomoe decides she is going to travel to the mainland to compete in the Queen's Blade tournament. During the night, Demon Ninja priests attack the temple.

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. Reina and Listy reach the entrance to where the Queen's Blade tournament is being held.

Claudette arrives where Reina and Listy were the night before and encounters Echidna who explains she let Reina go so that Claudette could become countess and hence reward her. Claudette goes to find Reina, and has a flashback to where she rescued Reina as a child.
