Video 【オリジナル・ボーカル】 Yonder Voice - 星空の花束

a.k.a. vocal version of "Carnation" by himmel.
Was about to flag this as "Touhou", even if it's an original arrange lol.
Anyway, this song is the ending of the Touhou doujin anime 「秘封活動記録～ The Sealed Esoteric History -月-」 as stated by the lyricist: https://twitter.com/anzumondsichel/status/678235249038364672
The lyrics are also similar to 決別の旅's and seem to be related to Maribel and Renko.
Himmel is the name LEMiao uses for original compositions, by the way.
