I really like this game, all I know is that it's available for the PlayStation Vita, I don't know if it's for the PS4.
But non this game you are visiting you uncle because your parents are away on business. Your only staying there for a year. Your uncle is a police officer and has a daughter named Nanako. You go to school and meet two girls and a boy. You hear a rumor about the midnight channel. At midnight while it's rainy you look at your tv and you might see your soul mate. You decided to try this and you touch the tv. Only to be surprised that your hand goes through it. You tell your friends about this the next day but they don't believe you. So you prove it to them by going to a mall looking at TVs. You put your hand through the tv and end up falling in along with one of the girls and a boy. When you crash to the bottom you see that your in a foggy tv studio. Along the way you also meet a teddy bear that tells you about shadows and personas.
While playing the game a bunch of murders are happening that are connected to the midnight channel. You and your friends use your personas to find out who the killer is.
Find out the rest on your own I can't spoil anything.
