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 BandMaid 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 OkyuJi 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 BandMaid 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 BANDMAID personal best of playlist (at this point in time, from what I know by them so far and in no particular order) plea
