|Name (Romaji)||Leonora Lancaster|
|Novel||Seirei Tsukai no Blade Dance Light Novel Volume 04|
Leonora Lancaster is the Dragon princess of the Dracunia Empire and Leader of the Knights of the Dragon Emperor team. She is sometimes effected by the «Dragon Blood» in her body, which makes her act on impulses and unable to think straight.
Leanora has thick bright shoulder-length black hair, and is described by Kamito as an icy beauty. Her eyes are normally black however, when afflicted with the dragon's blood her eyes become burnt with a smoky red glaze. She also wears glasses to read as she has poor eye-sight. She uses spirit magic during the blade dance to strengthen her vision.
Leonora generally has a calm, careful and analytical temperament. She is a hard worker, and is not a person that will underestimate her opponent. She is usually straightforward.
Her true nature is described by Kamito as noble-minded and elegant, fully of chivalry—and above all, loyal to her combat instincts.
She approaches Kamito as he was staring over the ship's railing. She mentions the (faulty) intel the spies of Dacunia gathered about him which annoyed him, she then introduced herself. When Kamito asked what business she had for meeting him, guessing that it was to kill him before the Blade Dance. Leonora refuted it, saying that they will defeat him fair and square in the Blade Dance. When asked again she flusterdly said that it was to "cut off that" and drew her sword. Kamito, now worried, asked her to clarify what that she want's to cut off. This made her even more flustered and swung her sword down missing Kamito by a paper-thin margin. Kamito still did not know what Leonora was talking about until noticing her staring at his lower regions which she confirms, justifying her actions that it is to prevent him laying his hands on her subordinates. He denies it but she doesn't believe him and called him a "perverted brute of a maou". She then witness him trying to clear the misunderstanding but she does not listen to him and then attacks him. She was later stopped by Claire's Flame Tongue and identifies Claire as Kamito's 'toy slave spirit' causing some dissent. As both Leonora and Claire stared down Kamito, the ship was attacked.
She was able to identify the attacking spirit as Dracunia's main military spirit, Death Gaze, that was supposed be sealed at the end of the Runbal War. When it attacked again, she was saved with Claire by Kamito but she fainted after he had grabbed her breast. She later wakes and summoned her spirit Nidhogg in it's purified form and defeated Death Gaze after Kamito was unable to finish it off. She comments to Kamito that his finish was weak. She was then thanked by Kamito but she said that it was Dracunia's responsibility since it originally was theirs. The three discussed what happened and identified a small ship which the military spirit came from but couldn't go after them due to not having a flying wind spirit and there might be more military spirits on board. When the rest of Team Scarlet came on deck Leonora returned her spirit into a sword and takes her leave but not before stating aloud that she will not allow what she thinks Kamito's wish is causing the team to question him for an hour.
- According to her, dragon spirits do not let their contracted maidens wear underwear.
- She is the first girl besides Fianna to figure out she is in love with Kamito.
