"Quicksilver" is the archaic name exclusively given to female poltergeists, ghosts that like to pull pranks. They break furniture and throw things around, as well as write the letter Q on windows and mirrors with soap or lipstick. They are easily bored, not staying in the same place for very long. In general, they are not dangerous spirits.

Quicksilver can be found in Kasumigaseki. Flynn will need the Demolingual App in order to communicate with her. Quicksilver can teach Flynn the Mazio skill through her Demon Whisper. Alternatively, Quicksilver will evolve from Poltergeist once it reaches level 17. Quicksilver can also potentially give Flynn the "Isis' Search for the Coffin" Challenge Quest if spoken to.
