After nearly a decade of twists, resets, and emotional damage, Re:ZERO − Starting Life in Another World is gearing up for its next chapter. Season 4 has been officially confirmed to premiere in April 2026, landing right in the middle of the series’ 10th anniversary year.

Alongside the date, the franchise dropped a wave of anniversary updates, including a new digest trailer revisiting key moments from past seasons and a second main trailer for Season 4 featuring brand-new footage. But the detail that’s getting the most attention is the opening theme: “Recollect,” performed by longtime Re:ZERO vocalist Konomi Suzuki, this time joined by Ashnikko.

It’s an unexpected pairing on paper, but one that feels very in-step with where anime music has been heading lately. Suzuki has been part of Re:ZERO since the beginning, while Ashnikko brings a very different, internet-native energy to the mix. The track is produced by Giga and TeddyLoid, a duo known for pushing J-pop and vocaloid-adjacent sounds into darker, heavier territory.

Beyond the new season, the anniversary plans lean hard into fan engagement. The official 10th anniversary site is rolling out quizzes, episode voting, and Q&A projects with the production team. There’s also a first-ever Re:ZERO exhibition scheduled to run in Tokyo this fall, offering a look back at the anime’s decade-long run.

Season 4’s story picks up after the brutal events in Priestella, with Subaru setting out toward the dangerous Pleiades Watchtower in search of answers, and a way to undo what’s been lost. WHITE FOX returns as the animation studio, with much of the core creative staff staying in place.

After ten years, Re:ZERO isn’t just continuing, it’s doubling down, expanding its world while clearly signaling that this next arc is meant to feel like a major moment, not just another season.
