Comment from MYTH & ROID
“Following our work on Season 3, we are honored to once again perform the ending theme for Re:ZERO -Starting Life in Another World- Season 4 as MYTH & ROID feat. TK (Ling tosite sigure).
Our new song, “Ender Ember,” was created around the theme of the lingering heat that remains after an ending. While carrying forward the time we have walked alongside Re:ZERO, we sought to capture and give shape to the emotions that resonate beyond the story itself.
With TK joining us as a featured artist, his unique expression has brought a new intensity to the track. As our voices intertwine, the song carries a depth and energy unlike anything we have created before.
We hope you will look forward to both Re:ZERO -Starting Life in Another World- Season 4, airing this April, and to “Ender Ember.””
Comment from TK (Ling tosite sigure)
“Within the history that MYTH & ROID and Re:ZERO have built together, there are beautiful melodies—drawn, and then destroyed, again and again.
In helping with this collaboration, I focused on how I could push back against the oncoming despair with a different kind of despair, rewriting it, adding a new kind of threat, a new kind of tension.
What I was able to draw within pages that never truly end, pages you can’t escape, still isn’t entirely clear to me, even now. When everything has slipped away from memory, I hope we can meet again, as if by fate.
I’m truly looking forward to the broadcast of Re:ZERO -Starting Life in Another World- Season 4.
Congratulations on the 10th anniversary.”
Collaboration With Tottori Prefecture
A collaboration with Tottori Prefecture has also been announced to coincide with Season 4’s broadcast. The partnership is inspired by the Auguria Dunes, a location featured in the upcoming storyline, which resembles the famous sand dunes found in Tottori.
A special collaboration visual has been released, with more details expected to be revealed later.
Story Overview
In the aftermath of the deadly battle at the Watergate City of Priestella, Subaru and his allies manage to claim victory, but not without severe consequences.
Due to the Authority of Gluttony, Rem remains trapped in an endless sleep while Crusch loses her memories, and even Julius’s name is erased.
While searching for a way to save them, Subaru learns of the existence of the wise man Shaula, said to possess limitless knowledge. His journey leads him to the Pleiades Watchtower, located deep within the dangerous desert known as the Auguria Dunes.
The region is so treacherous that even the legendary Sword Saint Reinhard could not conquer it. Facing deadly natural hazards, mysterious mabeasts, and overwhelming danger, Subaru and his companions set out on a perilous journey to reclaim what they have lost.
