Since you were led here from Nerissa, I'm recommending a video that Miori rates very highly: Zephyrianna's cover of Not Photogenic has a pinned comment from Miori (Miori herself has a short cover of the same song). Zephyrianna is known for her metal/screamo remixes and covers. Her group entry as part of Trash Panda won the best Villain Vilbes cover contest held by AmaLee and Mori Calliope; it has a very stylish MV.
For me, Miori is one of the best Vtuber singer of them all. With Izuru From Holostar jp, that have done too this cover. (ps. if you want react to him, with some of his song).
If you enjoyed this song i suggest checking out her and Bae's cover of "Gimme x Gimme" since they have been friends for a while they make a great duo cover.
