What is the name of the goddess of fire?

It has something to do with the heroine Mikaya

The heroine Mikaya is called "the witch of the dawn" in the game. She has the ability of divination and can achieve some incredible things.

However, after going deep into the game, it was discovered that such power was actually caused by another soul attached to Mikaya, and this soul was Yunu, the goddess known as the "goddess of chaos", who was integrated with the goddess of creation in the temple. Later, the goddess thought changed, and the soul was divided into two parts. One is called the goddess of order, which is absolute order, and the other is the goddess thought biased towards human beings.

So at last Yunu in Mikaya woke up, and she was really called the goddess of dawn.
