This is a cover of a vocaloid song by Kikuo with English lyrics written by Nerissa herself. I thought she did a really good job with the lyrics. 9 times out of 10, English localizations of Japanese songs sound awkward because of the completely different prosody and speed of the languages, but I don't detect any of that awkwardness in this cover; probably doesn't hurt that the lyrics in the original are delivered at a slow, even pace, but that still doesn't make it easy. And her delivery of the lyrics really demands your attention, effectively channeling the anguish of the protagonist.
I think what sets this cover apart is not just her vocal chops, but the fact that she clearly had an artistic vision for her performance, giving it depth which is missing from a lot of covers which technically execute the material but end up sounding flat. Been bumping it constantly ever since it dropped.
