Especially Lui since she tends to speak quite slowly (unless she's excited), very politely and in a easy to follow way.
What I mean by that is that while speaking, she usually takes a short pause after saying a few words or before particles in her sentences, which helps a lot when you're trying to keep up.
I highly recommend her Dragon Quest streams, they are amazing if you want to practice both your reading and listening skills.
You need to be careful though, because Lui
is a complete dork...
