I have reached Yuki nirvana
Kajiura looks kewl.
Most probably Kajiura herself since it's the only OST she could be credited in the music and I believe she already confirmed in her tweet before that there will be homura arrangement intro BUT never mentioned Shiina in that regard...But then we got Hyakka Ryouran in Katsugeki arranged by Fukusawa(INSTRUMENTAL VERSION) soEdit: The track that plays during the opening credits is a Homura arrangement. No sure if Kajiura since it has brass hue. Some parts are very Kajiura-ish but others aren't... Mebbe it was arranged by Go Shiina?
