Before everything turned dark because management and Akimoto insisted to push one person of a group and we never got light songs in the senbatsu again. If they had switched center they could have been a versatile group. Imaizumi didn't feel the atmosphere and graduated. She didn't join a group to feel mainly solitude. I feel Sakurazaka 3rd gen have the perfect balance now. Where there is a Seijaku no bouryoku there is a Natsuno Chikamichi. Switch center change the atmosphere even though they stick to same world. Not really sure if world of zelkova 🌳 was supposed to be mainly despair. The new world 🌊 that 3rd gen are bringing to Sakurazaka is also despair. Both don't trust love which is ironic when there is only love in this world 🌳 and love is impatient in 🌊. World of zelkova didn't trust love from adults and world of sea doesn't seem to be simple-minded to trust love. 2nd gen brought world of sakura 🌸 which has to rely on world of zelkova 🌳 to get non-love songs. It didn't work out because they couldn't move on from Keyakizaka. Only solution was to move to a new world and leave Conifer Forest for ZOZO Marine. It's quite easy to understand the world of sea if you're a fan of Luna Sea.
