Inu X Boku Ss Vol 1
Inu X Boku SS: v. 1 "First published in Japan in 2010 by Square Enix Co., Ltd."--Colophon. Full description
The threat of the Night Parade of a Hundred Demons has driven the residents of Ayakashi Hall to take refuge at their family homes--whether they'd like to or not. But when they're apart, the situation seems even more hopeless, and one by one the group reassembles at the place that brought them together. Whatever the future holds, they will face it with a united front!
Efforts to reunite the members of Ayakashi Hall take an unexpected, tragic turn when one of their number falls in the battle. The death of a close friend serves to strengthen the remaining throwbacks' resolve to prevent the grim outcome relayed by their future selves, even if it means exposing the dark truth of one of their most trusted allies.
