カゲロウデイズ公式アンソロジーコミック-DOWNER-

Fourteen mangaka take Shintarou Kisaragi, Tsubomi Kido and the rest of the Mekakushi Dan in the opposite direction from the Upper volume, writing serious and dark chapters. Memory, loss and a rumoured ghost girl run through the book, with one story named for a square shaped memory and another set before the cherry blossoms fall. Suou provided the cover, and Enterbrain released this half of the pair in March 2013.
