Thousands of years ago, the God and Goddess of creation (Izanaki & Izanami) placed their power into creating all of the isles of Japan and as well creating the Gods and Goddesses of their succession. When the God of Fire was born, Izanami died from the horrible bur marks. She was sealed in the Underworld. Izanaki could not wait to see his wife and he went to the palace of the underworld. There he saw his wife's dreadful body with worms crawling all over it, and the terrifying gods of thunder. Immediately Izanaki ran away and he used a big rock to block his wife from running after him. That is the rock which divides the underworld and this world. Now, in the present day, the rock has been cracked and Izanami, in a fury of her husband's hasty retreat, has now taken control of the Underworld as her own, cursing the normal realm as a 'blasphemic creation'. But the present guardian of the Earth, Orion, has also noticed this crack in the rock of the Underworld and has began to recruit and train those with 'Shining Stars'. These warriors have a soul that is worthy to control the power of the Mythic Beasts. These are the Shinwa Sentai Yajuranger.
