Nine Goddesses

Nine Goddesses (9体の女神) are legendary figures who appeared two hundred years ago in the New World. They took part in the fight against the Evil Deities when the New World was in the midst of total chaos.

Background

Responding to this calamity, the Nine Goddesses join the Thirteen Heroes' cause in combating the Evil Deities, defeating each of them one by one.

The Nine Goddesses have descended down from the heavens to enter into combat with the Demon God King and his subordinate demons. Alongside the Thirteen Heroes, the Nine Goddesses have managed to vanquish the Demon God King and his army. In the end, the demons' reign of terror on the continent was finally over at last.

In the present time, the carnage from such a battle can still be visibly seen to this day. Zaryusu Shasha noted in a certain place, it was possible to find old traces of that destruction from back then scarred there.
