Makaria制作のスペシャル。全1話、完結。
Kurayukaba is set in an alternative world, in a town where people have begun to fear falling shadows and the coming of the evening as a result of strange, mass disappearances that occur at night. After a chance encounter with a young woman named Tanne and her armored train, Shoutarou, a good-for-nothing detective, attempts to solve the case once and for all.
