Aoi's original name was Kazumi D Imata. But the more I thought about it, the name "Imata" didn't seem to fit her, then I changed it to "Aoi" but I couldn't quite figure out a full nam for her.

I actually put her name as "Ocean D Aoi" to be ironic. You know, since the ocean is her weakness as a devil fruit user. But it just kinda stuck.
