Faith: Elina's Unshakable Bond

"Faith: Elina's Unshakable Bond" is the twenty-fifth episode of the Queen's Blade anime.

Story
After winning the tournament, Leina takes her solo leave, leaving Claudette as the de facto ruler of Gainos. Tomoe has returned to Gainos and starts a journey with Aldra. At the Vance castle, various nobles living nearby are not too happy that Leina won the Queen's Blade tournament and have formed a joint army to attack the castle. Elina manages to hold off the invading forces long enough for her father to escape, but she is defeated by Echidna (who was hired by the nobles) and captured. Having collected her reward and having nothing better to do, Echidna sticks around and teases Elina by tickling her for a while using her pet snake, but Elina is adamant that Leina will come and rescue her. Elina remembers that she and Leina were very close after their mother had passed away, but as the sisters grew up Leina became more distant. Time has passed and the nobles are ready to execute Elina. As the archers get ready to shoot Elina, she begins to doubt whether her sister will actually come and rescue her. At the last possible moment, Leina shows up, defeats the enemy soldiers and saves Elina. While Leina rescued Elina, Echidna watches from the sidelines with amusement. After being saved, Elina convinces Leina to share a bath and sleep together. The next morning, Elina challenges Leina to a fight and if Leina loses then she has to stay by Elina's side forever. Leina easily disarms Elina and sets off on her trip once again. Echidna comes down to ask Elina if it's okay to let Leina go, and Elina states that it's okay because Leina promised that one day she, Elina and Claudette would live together. For now, Leina has asked Elina to go to Gainos and help Claudette, and Elina becomes a commander at Gainos and receives a brand new outfit.
