Translator's note: the original line for Nagisa's "You punk ass-!!" was originally おんどりゃー, a "swear" originating from the Hiroshima region. Technically, swearing in Japanese is not the same as swearing in English, but おんどりゃー is not considered okay to be heard on TV, and it's often used when starting a fight with someone, so I went for something similar. I don't think "bloody punk" would have had the same effect.
