Also this is not exactly related, but I noticed that the nominated name for the character Isabella in Paradise Kiss is Yamamoto Daisuke "Isabella" and I wanted to ask if it could be changed.

The character is referred to as Isabella by everyone throughout canon. The only time we learn of her birth name IIRC is in a flashback from when she was a little kid.

I know it's "just" a fictional character, but to me continually referring to her by her birth name despite the fact that that is not the name she goes by is just really disrespectful and hurtful, especially when the formatting reinforces the idea that her birth name is her "real" name and her chosen name is just some nickname.
