My entry for the Game Illust challenge :D I can't believe I got done in time to submit! xD Sorry for the bad quality.

In Persona 3, you play as a silent hero/heroine (heroine playable in PSP remake) who just transfered to Gekkoukan High School and joins S.E.E.S, the Specialized Extracurricular Execution Squad, a group who investigates a phenomenon known as the Dark Hour. When the Dark Hour occurs, a tower called Tartarus appears containing Shadows, creatures who feed on the minds of humans. To combat the Shadows, the members summon their Personas. A Persona is thought of as a person's inner self and can only be summoned using a gun called an Evoker, that must be pointed directly to their head.

The basic jist is to live out a regular student life while figuring out the Dark Hour: why it exists, how it was created, etc. While doing so, you interact with the people of the city and create friendships with them. Doing so will enable you to create new Personas that you can add to your arsenal when you combat Shadows.

There is more to tell but I'll spoil the game for you! X3
