- "Those lost in life's labyrinth drift here. We are a light shining upon a path into the dismal future. I am the keeper, Sumaru Genie."
- —Sumaru Genie, Persona 2: Innocent Sin
The Sumaru Genie refers to both the location and the character that resides in it in Persona 2.
- Persona 2: Innocent Sin: Rumormonger
- Persona 2: Eternal Punishment: Fortuneteller / Affinity Readings
The Sumaru Genie grants fortunes with various effects, lasting for ~20 minutes in-game. In the PSX version, if the game is saved while a fortune is in effect, the timer is reset when the save is loaded, creating a way for players to have a single fortune's effects last through the entire game; this bug was fixed in the PSP version.
- "A husky-voiced fortune teller who knows a lot about rumors. Rumored to be seen sometimes in the parts of the city that come alive at night..."
- —Introduction paragraph
The Sumaru Genie is a location in the Kounan Ward filled with Egyptian motifs and paintings on both sides of the wall. It houses the character named after it (or perhaps more accurately, the character it is named after), the Sumaru Genie. She is a non-playable character who functions as a Rumormonger as well as a fortune teller who can tell the fortune of Tatsuya Suou if the player pays 3000 yen.
When the party arrives to talk to her to further the search for information about the Masked Circle, she redirects them to "the man at the Honmaru Park" where they can find more information.
As the game goes on, the Sumaru Genie eventually admits that she is actually an intersex clubber who pretended to tell fortunes and eventually got stuck telling real fortunes due to the power of rumors. She also mentions that she owns a bar and invites Tatsuya to it at the end of the game.
