Shingetsuha (新月破) is one of Xaldin's weapons in Kingdom Hearts 358/2 Days.

This weapon's translation "torn new moon" may be a reference to the main characters from  Final Fantasy IV from the second moon that led both the protagonists and antagonists, and therefore opposed each other. Cecil Harvey was the leader of the party of protagonists, and was later joined by fellow Lunarian, Fusoya. They opposed Zemus, as well as  Golbez until he was no longer brainwashed and became a protagonist.
