Summary

• Kingdom Hearts 4 introduces the "Lost Master Arc," marking the beginning of the end of the saga.
• Fans speculate that Star Wars or Marvel worlds may be included in Kingdom Hearts 4.
• Tetsuya Nomura hints at resolving the fate of the Lost Masters, teased at the end of Kingdom Hearts 3.

Kingdom Hearts co-creator Tetsuya Nomura recently hinted at an update for Kingdom Hearts 4. The next chapter in the expansive Kingdom Hearts saga was officially announced in 2022 with a cryptic trailer featuring the main protagonist, Sora, waking up in a mysterious, Shibuya-inspired city called Quadratum. Kingdom Hearts 4 will launch the "Lost Master Arc," described as the "beginning of the end" for the Kingdom Hearts saga.

Since the initial trailer, Square Enix has remained relatively quiet about Kingdom Hearts 4, leaving fans to analyze the trailer for story clues and potential new Disney worlds. Some fans have spotted hints suggesting that Star Wars or Marvel worlds might be included, expanding the series' Disney crossover beyond traditional animated films.

On January 9, 2025, the 15th anniversary of the 2010 PSP prequel, Birth By Sleep, was celebrated. Series director Tetsuya Nomura used social media to reflect on how Birth By Sleep utilizes the recurring theme of crossroads, or pivotal moments of divergence. He hinted that this theme could be significant in the "Lost Master Arc" of Kingdom Hearts 4, though he noted it was a "story for another time."

Tetsuya Nomura Hints At Kingdom Hearts 4

Nomura elaborated on the Lost Masters' gathering at their own crossroads in one of the final scenes of Kingdom Hearts 3, 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 cryptically suggested that the Lost Masters must lose something to gain something, referencing the crossroad myth from American folklore, a theme often revisited in the series.

Based on Nomura's recent comments, the resolution of what the Lost Masters lost and gained during their reunion with Luxu might be explored in Kingdom Hearts 4. While much of the game remains shrouded in mystery, Nomura's mention of these details could signal that more information, possibly in the form of another action-packed trailer, is forthcoming.
