Speaking of NPC's, I've got a total of 5 possible ones to choose from for my character, Ishiyama Tsurushi, but I'm having trouble deciding which three to use. The five NPC possibilities are...

[list][*] A grade school student from the class that Tsurushi teaches
[*] The principal of said grade school
[*] A therapist that Tsurushi regularly sees
[*] Tsurushi's current girlfriend, who coincidentally shares the same room in an apartment complex she's staying at
[*] Tsurushi's former boss, who owns a gentleman's club/night club
[/list]

EDIT: On top of asking which three NPC's I should go with, I'd like to ascertain some more info on the Lostman before I try and do anything with Tsuruchi's background. How exactly are we supposed to go about our characters' encounters with him? Would he vanish the second we laid eyes on him? Would he respond to our attempts to converse with him?
