I think its ridiculous honestly, they could do all that without changing the name. The concert proved they can in fact do it without techi, AND with multiple different centers, so this name change is really just a cop out from management. Keyaki was built with 21 members, 13 of them are still here, and they've gained 15 new talented idols to help them continue who have sparked the life and enthusiasm that we lost back in '17/'18. So this name change is honestly dumb lol..
On the bright side, I think most keyaki fans, while very hurt about the 're-brand', understand how the members have always felt pressured to 'fill in for techi' whenever she was absent, and would often try to imitate her aura when someone had to cover for her. I think a big reason as to why suzumon got so popular after centering Ambivalent was because she did it in her own style, and didn't try to imitate techi's version of the song. People say her own aura and liked it. I think this is also why Neru was so popular too. I do wish that the rest of the members didn't feel so much pressure to act a certain way.
So, while i'm completely against the name change, I think this will be good for the remaining members, they can finally rid themselves of this unnecessary pressure to carry the same aura as techi had in keyaki, and start to spread their wings as individual idols, rather than always doing things "for the sake of the group". I'm truly excited to see what they have in store for us. I would be happy to see similar dark songs like Mou Mori and Hiraishin, alongside some really softer songs like Futari Saison and Kimi ga Inai again. Having that nice mix would be good. The concert (along with tokyo dome last year) showed how creative and artistic the group is, so i would love it if they made that their new image.
