I Want to Love You Till Your Dying Day has officially confirmed its Japanese premiere date. The dark fantasy yuri anime will begin airing on July 7, 2026, bringing Nachi Aono’s emotional and violent manga to television with a new trailer, key visual, additional cast members and theme song details.
The new trailer gives viewers a stronger look at the anime’s haunting setting, where orphaned girls are trained as magical weapons for war. At the center of the story are Sheena Totsuki, a girl who hates violence, and Mimi Kagari, a mysterious child soldier rumored to be unable to die.
The Anime Premieres on July 7
I Want to Love You Till Your Dying Day is scheduled to premiere in Japan on July 7, 2026. The new trailer and key visual highlight the contrast that defines the series: a delicate yuri romance developing inside a brutal institution built to turn children into weapons.
The story is not a light school romance. Although it takes place in an academy-like orphanage, the girls living there are not being raised for ordinary futures. They are trained for battle, sent into war and forced to face death while still carrying the emotions and vulnerability of children.
That emotional contradiction is what makes the anime stand out. The series combines love, trauma, innocence and war in a way that makes the relationship between Sheena and Mimi feel both tender and tragic.
New Trailer and Key Visual Revealed
The latest trailer presents more of the anime’s dark fantasy atmosphere, showing the girls’ daily lives inside the orphanage, the shadow of war surrounding them and the strange presence of Mimi, who appears with a smile even after returning from bloody battles.
The new key visual also places Sheena and Mimi at the center, reinforcing the bond between them as the emotional heart of the story. Around that relationship is a world that treats young girls as tools, making their connection feel like an act of resistance against the cruelty around them.
For viewers unfamiliar with the manga, the trailer makes it clear that I Want to Love You Till Your Dying Day is not only about romance. It is also about survival, grief, emotional numbness and the fragile hope that love can still exist in a place designed to destroy it.
Opening and Ending Theme Songs
The anime’s opening theme is “Amore”, performed by ReoNa. The ending theme is “Éternel”, performed by sajou no hana.
- Opening theme: “Amore” by ReoNa
- Ending theme: “Éternel” by sajou no hana
Both song titles fit the identity of the series very well. “Amore” directly evokes love, while “Éternel” suggests something lasting and unending. For a story centered on romance, death and an immortal girl soldier, those musical choices feel closely connected to the anime’s emotional themes.
What Is I Want to Love You Till Your Dying Day About?
I Want to Love You Till Your Dying Day is set in a mysterious orphanage where girls are raised to become magical child soldiers. The world outside is shaped by war, and the children inside the institution are trained to fight rather than live normal lives.
The story follows Sheena Totsuki, a 14-year-old girl who dislikes violence and wishes the fighting would end. She is not especially gifted in magic, and her heart remains gentle despite the cruel environment around her.
One night, Sheena meets a strange girl covered in blood. Instead of acting frightened or broken, the girl smiles cheerfully. Her name is Mimi Kagari, and she is rumored to be the orphanage’s secret weapon, a girl who cannot die no matter how badly she is injured in battle.
When Sheena and Mimi become roommates, their very different views of war and life begin to collide. Sheena is disturbed by Mimi’s attitude toward violence, but she is also drawn to her. As the two grow closer, the story explores affection in a world where children are expected to sacrifice themselves without question.
Additional Cast Members Announced
The latest update revealed two additional cast members for the anime. Yumi Uchiyama will voice Fran, while Ai Kayano will voice Omi.
- Yumi Uchiyama as Fran
- Ai Kayano as Omi
These characters join the previously confirmed main cast, which includes several important figures in Sheena and Mimi’s world. The voice cast will be especially important because the anime depends heavily on emotional contrast, from quiet tenderness to the horror of children being used as weapons.
Main Voice Cast
The main cast includes Rie Takahashi as Sheena Totsuki and Rina Hidaka as Mimi Kagari. Their performances will carry the core relationship of the series, which is built around fear, curiosity, attraction and the emotional damage caused by war.
- Rie Takahashi as Sheena Totsuki
- Rina Hidaka as Mimi Kagari
- Asami Seto as Lizzy Seiran
- Yui Ishikawa as Ali Maud
- Yumi Uchiyama as Fran
- Ai Kayano as Omi
The casting brings together voices capable of handling both the softer and darker sides of the story. That balance matters because I Want to Love You Till Your Dying Day is not built only on shock or tragedy. Its power comes from the way warmth and affection survive inside a setting that constantly threatens to erase them.
Staff Behind the Anime
The anime is being produced by ROLL2. Yasushi Tomoda is directing the series, while Jukki Hanada is handling series composition and scripts. Kyoko Yufu is designing the characters, and the music is composed by Yukari Hashimoto and Michiru.
- Original creator: Nachi Aono
- Director: Yasushi Tomoda
- Creative advisor: Takudai Kakuchi
- Assistant director: Nao Enomoto
- Series composition and scripts: Jukki Hanada
- Character design: Kyoko Yufu
- Music: Yukari Hashimoto and Michiru
- Animation production: ROLL2
The staff will need to handle a very delicate tone. The anime has to preserve the beauty and intimacy of the relationship between Sheena and Mimi while also making the war-torn world feel dangerous and cruel. If that balance works, the adaptation could become one of the most emotionally striking dark fantasy titles of the season.
Based on Nachi Aono’s Dark Fantasy Yuri Manga
I Want to Love You Till Your Dying Day, known in Japanese as Kimi ga Shinu made Koi wo Shitai, is written and illustrated by Nachi Aono. The manga began in Comic Yuri Hime in 2018 and later continued through digital platforms connected to Ichijinsha.
The series has gained attention for combining yuri romance with dark fantasy and war drama. Rather than presenting love in a peaceful school setting, it places romance inside a system where young girls are disposable soldiers. That makes every emotional connection feel fragile and urgent.
The manga has also been recognized by readers who enjoy stories with unusual premises, dramatic worldbuilding and intense emotional relationships. Its anime adaptation now has the chance to introduce that story to a much wider audience.
Why This Anime Could Stand Out
The July 2026 anime season includes many fantasy and romance titles, but I Want to Love You Till Your Dying Day has a much darker identity than most. Its premise combines the emotional intimacy of yuri romance with the brutality of child soldiers and magical warfare.
That contrast gives the series a strong emotional hook. Sheena wants the war to end, while Mimi exists as a weapon that keeps returning from the battlefield no matter how much she is destroyed. Their connection raises difficult questions about love, mortality and whether someone raised only for violence can still experience tenderness.
The series may appeal to viewers who enjoy dark fantasy stories with strong emotional stakes, as well as fans of yuri anime looking for a story with heavier dramatic weight. It is not a simple romance and not a simple war story. It is a tragic blend of both.
Final Thoughts
With its July 7, 2026 premiere now confirmed, I Want to Love You Till Your Dying Day is shaping up to be one of the most emotionally intense anime of the season. The new trailer, key visual, cast additions and theme song reveals all point to an adaptation that understands the fragile beauty and cruelty of the original manga.
For viewers looking for a dark fantasy romance with tragic atmosphere, powerful emotional contrast and a central relationship shaped by war, Sheena and Mimi’s story is definitely worth watching. In a world that raises children to die, their love may become the one thing that refuses to disappear.
