[Auxilism]

As Keroko said, we should stop speculating. Therefore, I have another question. Magic is supposed to be non-lethal. However, in that episode where Nanoha stops Subaru and Teana, her hand was bleeding from Teana's blade. Since there is such a case of 'bleeding to death', was Teana actually using lethal magic? If her blade could draw blood, she could make a big and deep enough gash that would cause a person to bleed to death.
