Inu x Boku SS, Volume 9 (Inu x Boku SS #36-38)

At first, the residents of Ayakashi Hall are baffled by the discovery of a time capsule containing letters in their own handwriting, apparently from their future selves. But Natsume's ability to see beyond confirms the truth, and he is overwhelmed by the future he glimpses. The others aren't sure they want to know the full extent of what is to come when it has so obviously rattled Natsume and their later selves. Even with that knowledge, what can they do differently to face the Night Parade of a Hundred Demons?!
