Gumi just has the best songs, I swear. For awhile though I thought this was a song of Hachi’s. That being said I have never heard of YM before. I had heard the chorus of this before the actual song but that wasn’t what impressed me. It was an Umineko MAD done later. Really, that’s pretty clever. This song is tailormade for that series, it would seem.
Nico Nico Chorus ver.
Umineko no Naku Koro ni ver.
