Here's another one that just popped into my head; if someone creates a Music Hunter who's a Manipulator, this one's for them, though it could also work well with assassins.

Name: Sonata

Nen Type: Manipulation

Description: The user plays an instrument; anyone who hears the music can be controlled by the user any time after hearing the music; susceptibility is only removed once the 'victim' has been controlled. Once the control has been removed, the 'victim' is immune to being controlled again, even if they hear the music again. The victims don't have to be controlled immediately; instead, the user can assume control of them at any time after they hear the music, up to two days later.

Limitations (if you have any): The user must control 'victims' within two days or else the susceptibility wears off and they become immune to the user's control. The user must also be proficient in the use of an instrument, which means significant injury to the arms/throat (depending on the instrument) could prevent the user from using this power.
