Trivia

 * Isuka (イスカ) is the Japanese name of the red crossbill. According to a medieval legend, the crossbill gained its crossed bill by trying to free Jesus Christ from the cross by pulling out the nails, which caused blood to spurt out and stain the bird forever as a token of its efforts. This fits with Isuka being a righteous Marine and her epithet "Nailing".
