Call me Ishmael

"I challenge Anastasia Shelman from the rank 1."

This dude called Ishmael specifically singled out Anais (Anastasia), a very bold move on his behalf.

Being the special case, Fairy Meiying had already given us the privilege to decide who would accept the challenge. So, Anastasia didn't need to agree to the challenge just because the challenger asked for her.

However, if anyone except her went up the stage, the others would definitely scorn Anastasia Shelman.

But she was just a character Anais had portrayed in disguise. The prestige of Anastasia Shelman was nothing of her concern. 

And Anais was not the one to get swayed by the negative words from the ones she didn't associate with at all. 

The most important thing was her safety. If she didn't have any chance of winning, she wouldn't go up the stage. It was a promise she had given to me.

Thus, the final decision was in Anais's hands.
