I'd never seen that performance before, but wow it was good!
Also, I know this is so last week, but I really agree with mellody about ONENESS feeling directionless with everything just mashed together.
I'm loving Yozora too! I did not expect such a dramatic song with a rapper featuring on it, but I'm happy to be surprised.
That chorus is monstrously catchy, I could remember it after hearing it once and it's been playing in my head since yesterday.
