Hi there!
I'm not sure. I mean, is always hard to tell when it is Visustella. But also, their Message core add a LOT of functionality for the message system. So I really don't know if they work together. But My message scroll plugin needs another plugin of mine as a base(Message Manager, is free): https://hakuenstudio.itch.io/hakuen-studio-message-manager-for-rpg-maker
So first you will need to confirm if my message manager works with visu one.
When i make a test i will let you know.
