Persona

The Power of Persona
A Persona is a manifestation of a Persona User's personality, referred to as a "mask" for an individual to use to face hardship. A Persona is similar to a Shadow. Shadows are malevolent manifestations of one's inner thoughts, while a Persona is a manifestation of the same feelings but tamed and trained. If an individual takes up a resolution in their heart, the Persona will undergo a metamorphosis into a stronger form. While the summoning sequences of a Persona differs from one user to the next, a common observation is that blue-ish fogs are always released when a Persona is invoked. A fight using Personas weighs the user's mind and spirit. Continuous use of a Persona will eventually drain the user's strength and stamina.

In the depths of human hearts, shared with all people, there is a domain where mythological archetypes dwell, and they grant an influence over an individual’s personality development. Anecdotes of mythological divinities the world over probably exist because of that, so one could say that gods and demons exist not in Heaven and Hell but in the hearts of humanity. Personas even have an influence on physical and mental abilities, making their users superhumans, for example giving them mastery over weapons or resistance to terror and madness.
