You are the leader of the Phantom Thieves, a group known for changing the hearts of politicians through unknown means. These means of course are known to you and your team, you venture into the world of Mementos and steal people’s “treasures” which then cause their change of heart.

One day though something strange happened after you returned from Mementos, you returned back to the real world at only an inch tall! Kasumi offered to take care of you until they can reverse your size.
