Each day is divided up between various time zones, the most common of which are "After School/Daytime" and "Evening".
With the exception of scripted events, such as plot progression or special events, the player is free to choose how each day is spent, with most activities causing time to pass on.
Players will eventually come across boss floors, in which the player must defeat powerful Shadows in order to continue their progress.
During the Dark Hour, the player enters Tartarus, a large tower containing Shadows, creatures that feed on the minds of humans.
To fight the Shadows, each member of SEES is able to summon a Persona, a manifestation of a person's inner self.
Two fighting games that continued the storyline of select members of SEES, Persona 4 Arena and Persona 4 Arena Ultimax, were released in the early 2010s.
Persona 3 has also seen related forms of media released, including a rhythm game spinoff, multiple soundtrack albums, musical concerts and radio dramas, a manga adaption, an anime series, and an episodic animated film series.
New Personas can be created by visiting the Velvet Room and fusing together multiple Personas, passing along certain moves from the Personas used.
