[Love Live Waffles] Mitaiken HORIZON 

But before that, really it's a nice & hype intro performance on stage at LL! Fest in 2020 back then, just b4 pandemic start.. Aqours start performing Mitaiken Horizon for the first time in live concert, and it been watched by both their senpai, U's & kouhai, Nijigasaki (Liella not yet be form, but wonder if they actually attend as audience, Sayuri perhaps)..

Of course I know, I also did 💛💛
