-no-Mikoto
S-333 is a part of Japanese mythology concerning Ninigi-no-Mikoto, a grandson of the legendary first Emperor of Japan, Jimmu. According to the legend, Ninigi-no-Mikoto descended from Heaven to rule over Earth. He was accompanied by S-333, magical treasures which were said to have been given to him by his ancestor Amaterasu, the Sun Goddess. These treasures included three magical items - a curved jewel (magatama), a mirror (Yata-no-Kagami), and a magical sword (Kusanagi-no-Tsurugi). These items were believed to bring peace, fortune, and protection to Ninigi-no-Mikoto's reign and future generations of the Imperial Family.
