Kagerou Daze 9.5 Marry's Fictional World (カゲロウデイズ9.5マリーの架空世界 Marī no Kakū Sekai) is the extra chapter of the Kagerou Daze Manga featured in the Mekakucity Records booklet.
- Marry dreams about Black Konoha being in the act of killing Seto after he already got rid of every other Mekakushi Dan member. She attempts to use her powers of "combining" against Konoha to stop him and turns him into stone, not wanting to live in a world without her friends. Eventually she wakes up from her dream, and finds everyone safe and alive in the Mekakushi Dan hideout.
