Okay, I know this is old and my reply is off topic but I can't believe you said that about Kiryu. I'll admit I'm a bit biased but some of Kiryu's songs are some of the more unique songs I've heard or at least very memorable and definitely enjoyable. For example: Gabi no Sanagi wa Uko wo Shirazu, Misemono Kitan, Hanaichimonme, Oirantan, Tomoshibi, and others. I'm just surprised you said that about Kiryu, am I the only one who feels that way? (Seriously) And if so, I kind of want some examples of bands or songs that Kiryu/Kiryu's songs are an amalgamation of (which were also done better). I'm sincerely asking, not trying to start a fight. I'm always happy to learn new things.
Also, you have to admit, LILIA by Royz was pretty awesome!
Oh and I definitely love the Gazette but I haven't really listened to Nightmare that much, so I can't say, but I would guess the Gazette.
And yes, I created this account just to write this reply...
