Personally, I think the biggest stumbling block is the elephant in the room: Hirate*. Like it or not, the whole shebang that the group and fandom had to go through over the past 2-3 years, stems from her presence/absence and eventual withdrawal (not graduation). If you want to perform any song centered by Hirate, it is hard to shake off the ghost of Hirate. After the pain of the past few years and rebranding, who wants to bring back that ghost? Hirate looms too big over it, especially among those who were Keyakizaka fans. Prior to all this, if anyone who centered one, gets automatically compared to Hirate. While this is probably expected for any group, I find that too much attention is heaped upon the differences than is healthy. With Hirate gone, the remaining former Keyakizaka fans are likely to fans of the group or those who are non-Hirate oshis. They aren't so attached to Hirate, but Keyakizaka songs do carry a reminder of the past that is not all bright. I love the songs myself but I can't pretend that the whole baggage of the era doesn't exist. Among the present members, the first gen and second gen are the ones who have interacted with Hirate on a personal basis, and especially for the first gen, having gone through that time of pain. Practicing and performing Keyakizaka songs will just bring back all the memories. I'm pretty sure that's not what they want to do right now, given that SKZ has only been launched about a year ago. Sure, the management is driven by profits, but this is also shaped by what the market wants, or at least what they think the market wants. With all that drama of the past few years, SKZ is supposed to wipe the slate clean and restart. I find it hard to believe that the management will want anything that carries the taint of the past, certainly not these couple of years. Time can perhaps ease the pain and heal some of the wounds (among the former members and fans). Perhaps one day Hirate might actually come out and put all the doubts and questions to rest, thus bring closure**. Maybe. By that time, how many of the first generation would remain in SKZ? How many of the fans of SKZ were former KYK fans? At that time, would they care anymore about the old KYK tracks? So maybe, 5 years from now, Sony might decide to do a remastered version of Futari Saison, but I'd suspect that would appear in a B-side or maybe for a compilation album. Right now, I can only imagine Futari Saison getting this treatment. The heavier songs of KYK? I find that unlikely, considering the fit to SKZ. The non-Hirate songs? Maybe like something Bokutachi no Sensou and Bathroom Travel, but are these popular enough? As for the KYK tracks, they are up on Youtube, Spotify, etc, and will continue to bring in revenue for Sony. They may even let other groups (not SKZ) cover them, which brings in even more royalty. It's just that they aren't milking them as hard as before. * I'm not assigning fault, just point out the crux of the matter here. ** We never got any closure. Bokutachi no uso to shinjitsu isn't much of an expose. I hate to say this, but I have the same feelings with the current (and only single). The pandemic is not helping matters, but I worry about SKZ's survival as a group. Most of the current SKZ fans are likely to be former KYK fans. If this crowd doesn't get excited about SKZ, SKZ doesn't have a sufficiently large fanbase to serve as a spring board and will have to almost start from scratch. I hope I am wrong.
