Dororonpa!

Anko Daifukuji's new house already has an unwanted resident: Komachi Ono, a ghost who has refused to move on for a century. Even the prayer beads Anko receives from her priest grandfather cannot dislodge this experienced troublemaker.

As Komachi settles into the family's daily life, an apprentice angel arrives hoping to send her to the afterlife, and a devil complicates matters further. Living with a ghost proves less frightening than exasperating when nobody can persuade her to leave.
