Inabakumori has released a new song as an official demo for the synth RIME. I think this song does a great job of showing off how RIME is truly detectably different from KAFU in more ways than just pitch. This song has completely sold me on her voice.
As far as the song itself, the progression is very similar to his older songs but there are some unique elements here that I really like. The art for the PV is also really cool with plastic model fitting pieces as background elements.
