I now think that Aguri is Ace. She wears a red dress, similar to Ace. Their eye shape seems to be the same, so she should be Ace.

Some people think she is Regina, but I do not think she is. They did not have the same eye shape. But they have the same hair-side bangs and they seemed to have the same age.
