ako udagawa is obvious. she knows all their songs by heart. she can even play along with most of them. sometimes she listens to them together w tomoe!! i think she rlly fits the vibe babymetal had in their early days
next is MARI OHARA!!! she likes metal and punk and is an idol.....i feel like she would listen to more altidol groups. i think her fav album would be metal galaxy!
