Full Moon Operations are the major and main turn of events in the Persona 3 series. Full Moon Operations occur once a month during every full moon. In this event, one or two unusually strong shadows will appear. Also, during this day, the Protagonist or Female Protagonist can't do anything after school, or evening. He/she must go back to the dorm. These battles have a significant standard level. If the full moon drops at Sundays or holidays, the Protagonist or Female Protagonist must stay at the dorms.
