Shiori definitely sticks out in an awkward way. Not bad or anything but noticeable. I'm surprised that the twins have that much control and didn't really expect them to have the range they do. Nerissa has been in two songs tonight and already shown that she was a damn good pick up for Covers musical interests.
Song is decent, nothing wild but alright opener for a gen.
Still seemed to have the Engrish-y lyric stuff going on but there's been much worse songs in Holo alone. They need to sort out the balancing for a few things but otherwise yeah. Solid work Cover, yet another wave of solid choices. The weakest is Shiori so far who has been around for years and most likely just needs to settle down into her comfort zone.
