"K" anime - TRAILER MUSIC -please help with name of composer

[Porter]

I am just curious if anyone could help with finding name of composer for this trailer music.
It is beautiful, uplifting and relaxing strings and piano driven music with no info about composer.

My wild guess is someone from Elements Garden group but it could also be Tatsuya Kato, Seikou Nagaoka, Kei Haneoka, Jun Maeda and Co., Taku Iwasaki, Jun Ichikawa, Tsuneyoshi Saito... but I am not convinced about it.

The sound is quite familiar. I am also curious for your tips for composer of this piece of music which composer style it remembers you.

There is general info on official site music production: Starchild records...but could it be any help?

All the best
