Clearing an Isekai with the Zero-Believers Goddess

◇Ancient Dragon King’s POV◇

My youngest child has finally returned after several centuries.

I thought for sure she would come by herself, but she had a human man by her side.

At first, I thought it was a weak being that only had feeble mana.

However, this being is known far and wide in the demon lord army.

A user of Great Water Spirits that hasn’t shown up in several tens of thousands of years.

I have never met a human Spirit User this strong in my life.

At first, that personage told us the one we should be careful about is the Light Hero.

But now this one is being seen as even more dangerous than that.
