Water Spirit
This time around the case becomes more personal, as the power that gives Saiki the ability to see and talk to the dead is the very thing terrorizing her client.

Ghost Talker's Daydream
Saiki Misaki has been able to see ghosts since she was a kid. Now, working at an S&M club, her spare time goes to sending the spirits off to the other world by having to make them realize they're dead and have to leave. This would supposedly be a little bit easier if you didnt have a background of hardship and loneliness... and a perverted employer.
