by A special collaboration between Yamato Forever REBEL3199 and Love Live! has been revealed, bringing together two memorable characters from very different anime worlds. The newly released visual features Sasha from Yamato Forever REBEL3199 and Honoka Kosaka from Love Live! happily running through the streets of Akihabara, Tokyo.
The crossover celebrates Akihabara’s importance to both franchises. The area plays a role in the upcoming final chapter of Yamato Forever REBEL3199, while it is also closely associated with the original Love Live! series and its school idol group, μ’s.
The announcement arrives just ahead of the release of Yamato Forever REBEL3199 Chapter 7: Rainbow-Colored Reincarnation, which begins screening in Japanese theaters on October 30, 2026. Alongside the collaboration artwork, two new videos have been released on YouTube: a recap of the story from Sasha’s perspective and a short video featuring scenes of Sasha appearing in Akihabara.
The unexpected meeting between Sasha and Honoka gives fans of both franchises a chance to enjoy a crossover that connects a classic science-fiction anime with a popular school-idol series.
Yamato Forever REBEL3199 and Love Live! Collaboration Visual Revealed
The newly released collaboration visual brings Sasha and Honoka Kosaka together in a lively scene set in Akihabara.
Sasha is one of the important characters in Yamato Forever REBEL3199, the latest entry in the remake series based on the classic Space Battleship Yamato franchise. Honoka, meanwhile, is the central protagonist of Love Live! and a founding member of the school idol group μ’s.
In the illustration, the two characters are shown running happily through the streets of Akihabara. The cheerful atmosphere contrasts with the serious science-fiction conflict that forms the foundation of Yamato Forever REBEL3199.
The visual also highlights how anime can connect different fictional worlds through real-life locations. Although the two series have different genres, Akihabara provides a natural meeting point for their characters.
For Love Live! fans, Honoka’s appearance recalls the early days of μ’s and the series’ connection to Tokyo’s anime and idol culture. For Yamato fans, Sasha’s presence ties the collaboration directly to the events of the final chapter.
The artwork is therefore more than a simple character crossover. It celebrates the cultural significance of Akihabara and the different ways anime has used the district as a memorable setting.
Why Akihabara Is Important to Both Anime Series
Akihabara is one of Tokyo’s best-known destinations for anime, manga, video games, electronics, and idol-related merchandise. It has also become an iconic location in many Japanese pop-culture stories.
The district is especially meaningful to Love Live! because it is closely associated with the original series’ setting and the everyday lives of its school idol characters. The franchise follows girls who form musical groups and perform as school idols while balancing their school lives and personal relationships.
Honoka Kosaka is central to that story. As an energetic and determined student, she helps bring μ’s together and encourages her friends to work toward their shared dream.
Akihabara also appears in Yamato Forever REBEL3199 Chapter 7. Sasha arrives in the district during the story, creating the opportunity for this collaboration with Love Live!.
By bringing Sasha and Honoka together in the same location, the visual connects two different aspects of anime culture: the expansive space-opera tradition represented by Space Battleship Yamato and the music-focused school-idol world of Love Live!.
This shared setting gives the crossover a clear connection to both series rather than making it an unrelated promotional illustration.
Two New YouTube Videos Released Alongside the Visual
The collaboration announcement includes two additional videos for fans who want to learn more about Sasha and the upcoming film.
- Story Recap From Sasha’s Perspective
The first video looks back at the events of Yamato Forever REBEL3199 from Sasha’s point of view.
Because the story spans multiple chapters and contains mysteries involving identity, memory, and the nature of Desarium, a recap can help viewers remember the important developments before watching the final chapter.
Sasha’s perspective is particularly relevant because she is one of the characters whose understanding of reality becomes increasingly uncertain as the story progresses. The recap gives viewers an opportunity to revisit her journey and prepare for the questions that the conclusion is expected to address.
It may also be useful for viewers who have not watched the earlier chapters recently and want a refresher before returning to the theater.
- Sasha’s Appearance in Akihabara
The second video is a short excerpt featuring Sasha’s appearance in Akihabara in the film itself.
This clip connects the crossover artwork to the actual story. Rather than limiting the Akihabara connection to promotional material, it highlights the location as part of the final chapter’s setting.
Together, the two videos offer different ways to engage with the release: one provides background on the larger narrative, while the other focuses on a specific moment involving Sasha.
Both videos were released through YouTube as part of the promotional campaign for Yamato Forever REBEL3199 Chapter 7: Rainbow-Colored Reincarnation.
What Is Yamato Forever REBEL3199?
Yamato Forever REBEL3199 is the latest entry in the remake series of the classic Space Battleship Yamato franchise.
The project reimagines the 1980 theatrical film Be Forever Yamato and incorporates material from the television series Space Battleship Yamato III, which also aired in 1980. Rather than simply reproducing the original stories, the new production reconstructs their ideas with a different interpretation.
The series is structured as seven theatrical chapters covering a total of 26 episodes. Its theatrical rollout began in July 2024 with Chapter 1, The Black Invasion, and continued through subsequent installments.
The story combines space battles, political conflict, mysteries surrounding humanity’s enemies, and the personal struggles of the crew of the space battleship Yamato.
As the narrative develops, the characters face increasingly difficult questions about identity, memory, loyalty, and the future of Earth. These themes become especially important in the final chapter, which is expected to bring the current storyline to its conclusion.
The project continues the legacy of a franchise that has influenced generations of science-fiction anime fans while introducing its story to a new audience through updated animation and storytelling.
What to Expect From Chapter 7: Rainbow-Colored Reincarnation
The seventh chapter, titled Rainbow-Colored Reincarnation, is the final installment of Yamato Forever REBEL3199. It is scheduled to begin theatrical screenings in Japan on October 30, 2026.
The official synopsis raises several major questions about Desarium and the reliability of the memories that the characters have trusted.
As the reality Sasha has believed in begins to collapse, she loses even the evidence that she has lived the life she remembers. Alphon, meanwhile, reaches a frightening conclusion after questioning his own existence.
The threat becomes even more serious with the introduction of the Grand Reverse, a powerful nucleon bomb intended to reset all of humanity. With destruction approaching, the partisan fleet comes together, seemingly guided by fate.
Their final hope is the space battleship Arizona, which takes to the skies as part of the effort to resist the coming catastrophe.
However, the danger is far from over. Mother Desarium’s objective remains, and the true nature of Desarium itself is set to be revealed.
At the same time, Susumu Kodai remembers his promise to return to Yuki. With that promise in his heart, he takes the captain’s seat as the Yamato heads toward Desarium’s homeworld in search of answers and a future for Earth.
These story developments place Sasha and the other characters at the centre of a conflict that reaches beyond a conventional battle between spaceships. The final chapter also explores the meaning of identity, the truth behind memories, and the importance of promises.
The official synopsis suggests that the conclusion will connect several mysteries introduced throughout the seven-chapter story.
Final Chapter Also Reveals Its Ending Theme Song
Another important update for the final chapter is its ending theme song, titled “Haruka e, Eien e”, which can be translated as “Toward the Faraway, Toward Eternity.”
The song is performed by Junko Yagami, with Akira Miyagawa handling the arrangement. Its musical foundation draws on Shin Ginga Tanjō, composed by Hiroshi Miyagawa for the original 1980 film Be Forever Yamato.
The new arrangement connects the upcoming conclusion to the musical history of the franchise while giving the final chapter its own ending theme.
The song’s creative team also includes lyricist Yōhei Matsui. The release of the music video and the announcement of the song form part of the promotional campaign leading up to the film’s October 30 premiere.
For long-time fans, the connection to the earlier film offers a reminder of the franchise’s history. For newer viewers, it provides another link between the modern remake and the original Space Battleship Yamato works.
The ending theme is especially fitting for a final chapter centred on promises, the future, and the characters’ determination to discover the truth.

Why This Collaboration Matters to Anime Fans
The collaboration between Yamato Forever REBEL3199 and Love Live! is notable because it brings together two series with different histories, themes, and audiences.
Space Battleship Yamato is one of the foundational works of Japanese space-opera anime. Its stories explore humanity’s survival, the responsibilities of leadership, and the emotional costs of war.
Love Live!, by contrast, centres on friendship, music, school life, and the ambitions of young performers. Its characters work together to achieve their dreams through school idol performances.
Despite these differences, both franchises have developed strong connections with their fans and with real-world locations. Akihabara is the natural link between them, making it possible for Sasha and Honoka to share a scene that feels connected to both stories.
The visual also arrives at an important moment for Yamato Forever REBEL3199, as the franchise prepares to conclude its seven-chapter theatrical release. It gives fans a lighter promotional moment before the dramatic events of the final chapter.
For Love Live! followers, the artwork offers a fresh appearance by Honoka. For Yamato viewers, it highlights Sasha’s connection to Akihabara and creates another reason to look forward to the film.
