Kingdom Hearts co-creator Tetsuya Nomura has recently hinted at new developments for Kingdom Hearts 4. The next installment in the expansive Kingdom Hearts series was officially announced in 2022 with an enigmatic trailer showing protagonist Sora awakening in Quadratum, a mysterious city inspired by Shibuya. Kingdom Hearts 4 will initiate a new narrative called the "Lost Master Arc," described as the starting point of the saga's conclusion.

Details about Kingdom Hearts 4 remain scarce, as Square Enix has kept relatively quiet since the initial reveal. This silence has led fans to carefully analyze the existing trailer for story hints and potential new Disney worlds in Sora's upcoming journey. Observant players have identified clues suggesting possible inclusions of Star Wars or Marvel universes, potentially expanding the series' Disney crossover beyond animated classics.

Meanwhile, January 9, 2025 marks the 15th anniversary of Birth By Sleep, the 2010 PSP prequel to the Kingdom Hearts series. Director Tetsuya Nomura commemorated this milestone with a social media post discussing how Birth By Sleep utilizes the recurring theme of crossroads—critical decision points where pivotal events occur. Nomura indicated this theme might connect to the "Lost Master Arc" beginning in Kingdom Hearts 4, though he noted this discussion would continue at another time.

Tetsuya Nomura Hints At Kingdom Hearts 4

Nomura specifically referenced how the Lost Masters converge at their own crossroads during Kingdom Hearts 3's final scenes, where it's revealed that former Organization 13 member Xigbar is actually Luxu—an ancient Keyblade wielder who has been observing events from the shadows throughout the series. Nomura subtly suggested that the Lost Masters who meet Luxu in this scene must sacrifice something to gain something, referencing the American folklore crossroads myth previously mentioned in the series.

Based on Nomura's recent comments, Kingdom Hearts 4 may address what the Lost Masters lost and gained during their crucial meeting with Luxu. While much about the next Kingdom Hearts remains unknown, Nomura's current references could indicate upcoming reveals, possibly through another action-packed Kingdom Hearts 4 trailer.
