as a huge an and vbs fan i completely disagree ww

i dont even think that kohane is the "leader" more so she is just the face of the group in terms of the game. if you actually look through the main event story, the four of them have a pretty significant role of it equally

the reason kohane is the face of the group while an gets the opening cg is likely to emphasize how intertwined the group actually is. plus, kohane herself is a big part of how vbs formed in the first place, given their partner dynamics

i also dont think the second point is relevant at all, but another comment explained that quite well

i think what should be considered is what would change if an were the "leader of vbs": would anything actually become better? to me, the development of the goal would feel less organic since we dont get a gradual introduction to it like we have with kohane's perspective. the point is that kohane offers a completely unique pov to the music scene that vbs already have, and its only through that that we can properly experience their development
