A majutsu sword technique that Shirokaze develops as he is trying to recreate the Black Angel Burst. Just like the technique it attempts to emulate the user first collects energy on a sword, appearing as arcing silver lightning, and releases it in slashing motion. This technique is much weaker than the technique it attempts to be, but it requires much less chakra to perform and releases a blast that can be used much more accurately and quickly. As the name suggests the technique appears like a silver crescent moon when fired and is utilized to slash opponents from a distance. Before Shiro completed the technique it appeared as violently moving chakra around the blade and was released with a more wave like appearance making it less accurate. While this appears similar to lightning releases with the appearance of lightning on the blade it isn't actually a lightning release and doesn't share qualities with them other than a partial appearance. Currently Shirokaze's mastery of this technique has extended to the extent that he doesn't required the entire Fuju to perform the technique. Additionally, it would appear the reciting the entire incantation yields a more powerful effect.
