I finally listened to the whole single and watched the PV. I'm torn, because I half-like it, half-dislike it.
Hyakka Ryouran in my opinion has very good verses and bridge, but when the refrain comes up, I always think "why did someone turn on Parallel Hearts all of a sudden". However, I really like REMI on the bridge, Hikaru's solo right after it, and for the verse, I still think it sounds absolutely beautiful to have Keiko as lead, Hikaru on the low harmonies and Wakana on the high ones. It's Kalafina at their best, and I would love to see it live. When later in the song Keiko sings on her own, her voice sounds however less controlled and while Wakana sounds nice in the refrain, I just keep thinking of Parallel Hearts and can't get into it. The instrumental version of Hyakka Ryouran is amazing though, and the refrain part there sounds lovely.
I would have liked the PV a little more if it didn't try to mix the Japanese style with something that looked like a police/spy setting, that just feels out of place. However, that nit-picking aside, I love their clothes (and the hairstyles!) and their slow movements in front of the camera, feels strangely fitting, somewhere in-between Märchen’s frantic pace and Into the World’s calmness. I also liked the fading effects, the smoke and the shadows a lot.
Tombo is a song that tells me absolutely nothing. The girls sing it well (although Hikaru starting off feels so… bad), and it’s sweet, but like Haru wo Matsu and Mahiru, I will not go out of my way to listen to it, as it doesn’t feel special. They are clearly trying to convey emotions, but I think they’re overdoing it (especially Keiko and Hikaru, their dynamics fluctuate too much), and it just doesn’t appeal to me. I think it’s supposed to have a calming effect, but if I want to listen to something calming, I prefer Yasashii Uta.
KantanKatan is instead the track that I really enjoyed in this single. Just after one listen I was interested in it, which lately doesn’t happen to me with Kalafina songs, and even later in the day while doing something as mundane as the laundry I kept humming it. The instrumental is perhaps a bit more repetitive, but feels much more comforting than Tombo and I think the girls sing it better too. Wakana does sound different than usual in the way she sings, but I think all three seem less “forced” than in Tombo.
I’ll probably be listening to KantanKatan between Game of Thrones episodes, because it’s so soothing :) overall, I'm still torn though... I'm really curious to find out if seeing the songs live will make me change my mind.
