I could type exactly the same thing here as I did on the page of Inori Fukazawa. Amu is also a one year rookie or veteran, with her first title released in December of 2019. She has done slightly more videos compared to Inori, but not that many more (around 15 or so). The difference is that she started rather slowly and has picked up the pace somewhat in the last couple of months. So, still active.
