First time REACTION to [Band-Maid - Beauty And The Beast] Is it Miku singing this??

Hey everyone! If you are new here, I love japanese rock/metal music and already know and love a lot of amazing bands (Babymetal being my absolute favourite), but I never listened to Band-Maid before starting this reaction channel. So I have now listened to ’Conqueror’, ’Just Bring It’ and ’Brand New Maid’ and ’World Domination’! (I’m also doing the ’Online Acoustic Okyu-Ji’ -CD right now and that’s a completely different and incredibly beautiful side of their music!) Now we are starting ’New Beginning’, which is their 2nd album so it’s the earliest I ever heard by Band-Maid so far and also not composed by themselves (if I am correct). To be completely honest, the newer their music the more I love it, but I am also very curious to where this band came from and how their sound evolved! My BAND-MAID personal best of playlist (at this point in time, from what I know by them so far and in no particular order) plea
