The Persona series is a spinoff of Atlus' Shin Megami Tensei IP. Each game revolves around highschool students who battle monsters, using the personified form of their psyches known as Personas. However, each game is nearly self-contained with its own theme and set of characters. Battle portions of the games follow general RPG conventions, while the rest of the game borrows aspects from life sims and visual novels. Friendship with other characters directly influences your performance in battle and grants you new Personas to use.
