We Are All Connected.

Synopsis

After her sixth sense suddenly vanishes, Amami wanders aimlessly searching for her spectral friends. Their voices, their faces, even their presence is nowhere to be found. Amami quickly falls into a deep depression over the loss of the friendships she'd formed with the ghosts over the years, and Inoue and the rest of her living friends are at a loss for how to cheer her up.
