The latest question mentioned Nero’s friendship, so at least I can post a quick portrait of his right-hand, who’s his and only true friend.
I mentioned her before once or two:
She was Nero’s right hand when he was the Crime Lord. Tall, muscular, loyal and fond of pretty ladies. She currently runs the Crime Lord’s affairs in the Calixis Sector, filling in for Nero.

So, if I mention her or she suddenly appears in an artwork, you will know what she looks like and who she is… 💀
