黒曜日 (Kuroyoubi) is a duo and was formed this February as an Utattemita duo and started their online activity in June. (And, yes they are visual kei as well)
Members are 葉月(Hazuki)(vo.) and CRAY(Gt)
As for today they released their first single 「深紅アクアリウム」including a MV!
If you like DIR EN GREY you surely will love this song.
New track sounds a lot less Diru than the other one (which reminds me more of late-era ReS, tbh) - really like his voice. Curious to listen to the rest.
I’m kind of sure it’s a girl(woman).
The label they are on is also an (female)idol label.
And they being so secret about it
Guess just wanting to stay genderless.
