For those who have a Playstation Vita (but exclusive to Japan), a new theme has been announced. It’s part of the “Gensoukyou Shiki” (幻想郷四季, Gensokyo’s Four seasons) series and is centered on autumn.
Comp made the BGM! It should be an exclusive arrangement, and we don’t know which is the original tune, but I’ll update this post.

This theme will be available from tomorrow.

UPDATE: Apparently, according to a Twitter source, the arrange is Fall of Fall.
