Kotone Shiomi comes to Persona 5: The Phantom X on 24 September 2026

• Her limited banner runs until 12 November at 01:59 UTC.
• Atlus is bringing Kotone back with full voice acting, a new story, and a new HD 3D model.

What happened

Atlus is adding Kotone Shiomi to Persona 5: The Phantom X through a sync patch. The update is scheduled for 24 September 2026, and the reporting says the addition will roll out across all versions of the game, although the platforms are not broken out further. The available information does not mention a separate platform list, regional differences, or different release dates by version.

Kotone will get a limited banner that remains available until 12 November at 01:59 UTC. According to the source, if you pull Kotone through that banner, she can be permanently added to Wonder’s party. That makes the banner not just a temporary availability window, but also the route through which the character content is unlocked in-game. The source does not mention exact drop rates, a pity system, or any further details about the banner setup.

The announcement also mentions new story content centered on Kotone. In that story, Wonder meets her after a mysterious door in Paulownia Mall, after which he temporarily loses his memory of Tartarus. The source also says Kotone returns fully voiced with a new story and a new high-definition 3D model. No full plot breakdown, mission list, or concrete gameplay abilities are included in the available information.

The update is also tied in reporting to the 30th anniversary of the Persona franchise. That places Kotone’s addition within a broader set of Persona activities around the milestone, but the source does not specify which other anniversary plans are launching alongside her. The confirmed details are limited to Kotone’s addition, the banner period, the new story content, and her presentation in a new model.

Background

Kotone Shiomi is the female protagonist from Persona 3 Portable. Atlus did not include her in Persona 3 Reload, which makes her return in Persona 5: The Phantom X stand out in recent Persona news. That absence from Reload is explicitly mentioned in reporting as a contrast to her new appearance in the mobile game.

Persona 3 Portable released in 2009 and gave players the option to choose Kotone as an alternate protagonist. The new information about Persona 5: The Phantom X confirms that Atlus is now using her again in another Persona title, with full voice acting and a new HD 3D model. The source describes her return as part of a new story, but does not provide a full description of her role, her dialogue, or her exact place in the game’s main structure.

The available information also says Kotone can be obtained through a limited banner and then permanently added to Wonder’s party. Wonder is the protagonist of Persona 5: The Phantom X, and the new storyline has him meet Kotone after a mysterious door in Paulownia Mall. He then temporarily loses his memory of Tartarus. Those are the only concrete story points mentioned in the source; further details about the side story, mission scope, or involved characters are not specified.

The reporting does not mention a full kit, an element type, a role, or stats for Kotone. The exact contents of the sync patch are also not broken down beyond the fact that the addition will roll out across all versions of the game. As a result, the confirmed information is limited to the release date, the banner period, Kotone’s return as a fully voiced character, and the presence of new story and model assets.
