1x12 - Re-Kan!

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.
