Another quest made just for the PSP version of Persona 2: Innocent Sin takes players to Karukozaka High, the setting for Shin Megami Tensei If…. You can travel there by visiting the Climax Theater, a new element in the PSP release which lets players take on additional quests like "The Persona Robber."
This story begins with a dream where you get a request from an unknown person to investigate the Heart’s Rest. Tatsuya and his friends head to Karukozaka High where they see see students with ambition sapped from their souls. Tamaizu Nirasawa, a senior, is the president of the excavating and computer clubs. Nirasawa is said to have a unique way of thinking.
Haruo Wayland is another key character in the Persona Robber. Also a senior, Wayland is the lead singer in the band Inryoku-Achine and one of Eikichi Mishina acquaintances.
Atlus added extra demons to this quest too. Silhouettes suggest Persephone, a reaper type from Shin Megami Tensei: Strange Journey, is one of them.
