Under Night In-Birth 2 concluded its current slate of DLC during EVO 2025, marking the end of the game’s first season of content. It has been a long journey for the Under Night In-Birth series, and both director Kamone Serizawa and composer Raito have been thrilled to stay involved since the very beginning.
But what comes next? Where does Under Night In-Birth go from here? Kamone and Raito sat down with us to discuss the evolution of the series and the future of the game.
Kamone expressed his gratitude to players for their continued support. He never imagined that so many people would still be backing Under Night In-Birth 2 Sys: Celes on the main stage at EVO 2025—many years after the first game’s release and with back-to-back appearances at EVO’s main stage.
The development team has been working on Under Night for over 10 years, and Izumi recently wrapped up the final run of DLC for UNI2. Despite this milestone, Kamone and Raito shared that they still have plans for the series and would love to keep evolving it further.
With Raito on hand, we also had the opportunity to delve deeper into the game’s music. Over the years, Under Night In-Birth’s soundtrack has evolved significantly—from simple, short-looping tunes in the beginning to more elaborate compositions.
Raito explained that this evolution was influenced by the shift in platforms. Initially, the music was developed for arcades, where players experienced the game in short bursts with limited time. Transitioning to home consoles and PC allowed players to enjoy the music at a more relaxed pace, which in turn influenced his approach to composing.
This change is evident in Under Night In-Birth 2 Sys: Celes, where the music is more complex and drawn out, matching the deeper, richer gameplay experience fans have come to love.
