Chiyou never expected that there will come a day when he will be standing in front of Theia as an opponent.
The battle he had with her in the Sullegar Kingdom was just a small check on each other about their skills and level of experience they both have when it comes to combat and Chiyou admits that Theia has more experience in battle as compared to him.
But that doesn't mean that she can defeat him.
That was a different battle and this is going to be a very different battle that he never expected to be in.
But the challenge has been issued and it doesn't seem like Theia is going to change her mind soon, so Chiyou has to fight her to know the very reason why she did such a thing.
"I don't want to fight you Theia,
Tell me why you did such a thing to my friend and I will consider if I have to give you some punishment or not, depending on your answer.
