Season 3 of "To Your Eternity" is set to premiere on Saturday, October 4, 2025, after a two-and-a-half-year hiatus, with online streaming available on Crunchyroll. Based on Yoshitoki Oima's manga, this new season promises a more profound story and introduces numerous new characters.
The immortal being Fushi has spent previous seasons battling the Nokkers, entities intent on humanity's destruction, by changing forms across various times and places. Season 3 will bring Fushi into the "Modern Era," hundreds of years after the "Past Era."
To commemorate the upcoming season and its compelling narrative, animate Times conducted an interview with Reiji Kawashima-san, who voices Fushi, and Kenjiro Tsuda-san, who plays The Beholder. They discussed their reflections on Season 2, new characters to anticipate in Season 3, and the highlights of the new season.
Season 2's Fushi-Beholder Dialogue: The Heart of "To Your Eternity"
──Reflecting on Season 2, which episode left the most significant impression on you?
Kawashima: The scene where Fushi, compressed into iron, pondered why people's lives shouldn't be taken away resonated deeply. He mused, "There are still so many joyful things to experience, and it would be terrible to have that stolen." The Beholder's observation, "You've become quite human-like," and Fushi's simple reply, "Ah, that's right," truly encapsulated the essence of "To Your Eternity" for me. It was profoundly impactful.
Tsuda: Kawashima's mentioned scene had a powerful visual impact, featuring a deeply moving encounter and farewell. Since Season 1, I've been consistently amazed that such a young author as Yoshitoki Oima-sensei can craft such an epic narrative.
──For Season 3, which focuses on the "Modern Era," what aspects did you focus on or find challenging during the recording process?
Kawashima: I remember how I worked backwards to create Fushi's character since Seasons 1 and 2 were about establishing his sense of self. I would think, "When he reaches childhood, he'll acquire this trait," and so on for each volume.
For this "Modern Era," I felt that the story was about Fushi, who has now established his identity, giving something back to others. So, Fushi's approach has shifted. While Fushi has continued to grow mentally, his physical appearance hasn't changed. I focused on portraying the changes in his heart - how much he can devote himself to others and protect them. The concept of "protection" has also evolved. In the "Past Era," it was about physical protection, but in the modern world, it's more about emotional support. I tried to convey Fushi's struggles and efforts to figure out how to protect others in this new context.
──Shifting between those personalities sounds quite challenging.
Kawashima: I've been in the industry for 8 or 9 years. About halfway through, 4 or 5 years ago, I encountered "Fushi the Immortal." At that time, I could dedicate significant time to a single project, which I believe laid the foundation for my current work.
Tsuda: The story has undergone various changes and developments. However, I've consistently maintained a detached, matter-of-fact perspective when delivering lines for The Beholder, including the narration.
──The Beholder now offers Fushi advice, unlike at the beginning. Has your emotional approach to the character remained the same?
Tsuda: Yes, that's correct. I don't portray the character as being particularly empathetic or desiring to help Fushi (laughs).
Rising Star: Aoki Yuki Steals the Spotlight as Cast's Mood-Maker
──Is there any characters from Season 3 you're particularly interested in?
Kawashima: I'd say Yuki Aoki, who becomes a key character in Season 3. She's a bright, energetic, and lovable character who acts as a mood-maker. Despite her carefree and innocent perspective, she often hits the nail on the head and casually says things that lead to important realizations. I'm curious to see how Fushi's interactions with such a positive character like Yuki will influence him.
Tsuda: Since my role is limited, I'm looking forward to meeting new characters almost from the same perspective as the viewers. I can't wait to see what the new characters introduced in Season 3 will be like, and how the cast members will portray them.
──Do you have any behind-the-scenes stories from the Season 3 recording that you can share?
Kawashima: This time, we have a lot more cast members. Since Yuki and the others are attending school, I was surprised by how many young people have joined the cast.
Tsuda: From my perspective, it's like, "What? School?" (laughs)
Kawashima: Looking back, in Seasons 1 and 2, I was the newest and youngest member of the cast. But in Season 3, everything has changed, and now I'm surrounded by juniors.
Tsuda: It's quite moving to think that Kawashima-kun, who was once the newcomer, now has juniors on this project.
Kawashima: Among the new participants this time, some have said, "This is the first time I've passed an audition." It reminds me of my past self, and I find myself cheering them on in my heart, thinking, "Do your best! It's okay! Don't be scared!"
──Kawashima-san, you must have learned a great deal recording alongside Tsuda-san, haven't you?
Kawashima: Oh, absolutely, so much.
Tsuda: No, no (laughs). We're completely different types.
Kawashima: I tend to focus on form first, so I often observe Tsuda-san when he narrates. I've noticed he uses a lot of hand gestures.
Tsuda: I can't help but move. It helps me speak more easily.
Kawashima: It's not quite like a conductor, but the way the power in his gestures connects with the sound is amazing. Because of that, I've developed a habit of watching Tsuda-san during his longer narrations or monologues (laughs).
──Looks like Tsuda-san got to witness Kawashima-san's growth firsthand.
Tsuda: Not at all. He's been fully dedicated to the work since Season 1, so I never had any concerns. Now he's even the lead for this series.
Kawashima: That makes me happy!
──How about you, Tsuda-san?
Tsuda: I've intentionally avoided reading the original work since Season 1, so with Season 3, I'm often surprised when I receive the script (laughs). This allows me to approach each recording session with a fresh mindset.
Kawashima: Also, the atmosphere on set has become incredibly lively since (Megumi) Han-san joined as Yuki Aoki. By the time we record, the visuals are almost 100% complete in full color. Even with the lip-syncing set, she adds ad-libs that are so true to Yuki's character. Even when she makes mistakes, she maintains Yuki's high-energy persona (laughs). It was striking to me how this lively atmosphere was something new for "To Your Eternity."
Fushi's Dilemma: How Will He Respond to the Knockers' Offer?
──In the spirit of "The Beholder," which cast member from the first three seasons did you find particularly interesting during recording?
Tsuda: Kawashima-kun, without a doubt. We first met during "Fushi The Immortal," and our initial interaction was in the first episode, where there were just the two of us. His passion for "Fushi" is as if he's dedicating his entire life to it. That commitment hasn't wavered, and I truly admire it.
──I imagine it might be difficult for Kawashima-san to say "Tsuda-san," so let's ask about someone else (laughs).
Kawashima: "Fushi" has quite an edgy cast, so there are many interesting people. But among those who have been involved for a long time, I'd have to say (Takehito) Koyasu-san, who plays Bon. Initially, Bon appeared to be a wild and crazy king, but then he became more serious. Even when he came to the present world, I was impressed by how he interpreted the character. The author even said, "Thank you for portraying Bon so wonderfully." I, too, thought, "Wow! How interesting!" seeing Koyasu-san's high-level skills in enhancing Bon's depth in the anime.
──Fushi absorbs various things. Is there any cast member from whom you'd like to absorb certain qualities?
Kawashima: If I could become a woman, the instrument (voice) would be different, and my perspective and sensibilities might change too. So, I'd love to be able to act with a female voice actor's voice.
Tsuda: My voice is generally low, so I'd like to have a high-pitched voice. I've never played a character with a high voice before. If I could produce a high voice, I feel like I might see a different world, so I'd love to experience that.
Kawashima: If we're talking about that, then I want Tsuda-san's deep voice too! I'm curious about how it would resonate within me, and I'd love to master it.
──Now that you've been involved with "To Your Eternity" for a while, what do you find particularly appealing about it?
Kawashima: "To Your Eternity" has made me realize that there are many things we tend to overlook in this information-saturated world. Every time the author presents something important through this work, it gives us a moment to pause and reflect. And it's not like a stiff lecture; it has a casual, conversational feel that makes it easy to absorb.
There have been moments during recording when I've had sudden realizations, and being involved with "To Your Eternity" has changed my way of thinking and seeing things. In Season 3, I've come to appreciate the importance of everyday life that might seem mundane, and I feel like my daily approach to things has changed. I think the charm lies in how it allows us to think and gain insights while enjoying the story.
Tsuda: It's a profound work reminiscent of masterpieces like Osamu Tezuka-sensei's "Phoenix," and I'm amazed that the author, Yoshitoki Oima-sensei, has reached such a level at a young age. I'm also impressed by his courage to tackle such a grand theme.
It's surprising that someone decided to adapt this into an anime, and the staff has done an incredible job maintaining such high quality. I believe it's establishing a significant presence and position in the current anime scene, and as an actor, I'm grateful to be part of such a project.
──Please tell us about the highlights of Season 3.
Kawashima: In Season 3, which depicts the "Modern Era," the Knockers strongly assert that their purpose is to "bear pain on behalf of others." Until we recorded Season 3, I actually thought the Knockers' claim sounded good. I was like, "What could be wrong with taking on someone else's pain? It seems like a great thing!" The highlight will be seeing how Fushi and the others interact with various people and come up with their own answers to this seemingly perfect and appealing proposition.
Tsuda: On a fundamental level, I was shocked that we suddenly came to the modern era. I thought, "Wow, it's finally becoming our story! The author is amazing!" (laughs). So, even during the first recording session for Season 3, it felt very strange. I mean, Fushi is living in the same time period as us! Just like the viewers, I found the "Modern Era" arc particularly fascinating.
──Finally, please share a message for everyone.
Kawashima: First, I'd like to thank everyone who's been waiting for "To Your Eternity Season 3." For those who are new to the series, this "Modern Era" arc corresponds to the second chapter of the original work. While you can enjoy it starting from here, there's a richness that comes from the accumulation of the past - 40 episodes in the anime's case. Since this is a long-running series that started in 2021, you might find yourself thinking, "Oh, so that's what that line was referring to!" For those who haven't seen Seasons 1 and 2, I'd be delighted if you could watch them on streaming platforms or read the original manga.
Tsuda: I'm grateful to those who are learning about "To Your Eternity" for the first time through this article and decide to start with Season 3. However, just as Fushi changes vessels and absorbs various experiences, the story's intrigue grows progressively. It's a grand narrative that's worth watching from the very first episode of Season 1. I recommend starting from the beginning if you can.
To the fans of the original work and those who have been watching the anime from the start, thank you for your patience. The broadcast is just around the corner. If you take the time to review the series before then, I believe you'll feel an even greater sense of depth in Season 3. I invite you to become "The Beholder" of this epic story.
