Nia Liston: The Merciless Maiden Anime Reveals Ending Theme Song Performers and Character Vocal Unit
There is something I really like about anime that refuses to take itself too seriously all the time. Nia Liston: The Merciless Maiden already has a ridiculous premise in the best possible way: an undefeated legendary warrior gets reincarnated into the body of a painfully sick noble girl and immediately starts looking for ways to get back into the kind of fights that nearly killed her in the first place. Now the anime has added another weirdly fitting piece to that formula with its ending theme, and honestly, I think the choice makes a lot of sense.
The upcoming Fall 2026 anime has revealed that its ending song will be “Tokimeki Un Deux Trois♪”, performed by a special character vocal unit called Magic Vision Girls Party. Instead of bringing in another unrelated pop artist, the production is letting the actresses playing the main girls perform the song themselves. Honoka Inoue, Rina Honnizumi, and Rina Hidaka will join forces for the ending, giving the track a much more direct connection to the characters.
That is a pretty clever contrast when you look at what Nia Liston is actually about. This isn’t a soft school comedy where three girls spend every episode drinking tea and talking about their feelings. Nia is basically a battle maniac trapped in a fragile body, and the story constantly plays with the difference between her adorable appearance and absolutely terrifying personality. Having the same characters suddenly appear in a cheerful ending sequence feels like exactly the kind of tonal whiplash this series should embrace.

The Nia Liston Ending Theme Is Performed by the Main Cast
The biggest news here is obviously the Magic Vision Girls Party lineup. The unit features three actresses who are already central to the anime’s cast:
- Honoka Inoue as Nia Liston
- Rina Honnizumi as Hildetora Altoir
- Rina Hidaka as Reliared Silver
I’m especially interested in Honoka Inoue’s role because Nia is not exactly a normal reincarnation protagonist. The character needs to sound physically vulnerable while also carrying the personality of someone who has spent an entire lifetime becoming an absurdly powerful warrior. That contrast could make or break a lot of the anime’s comedy.
Rina Hidaka joining the ending unit is also a fun touch. She has plenty of experience behind the microphone, so hearing her alongside the younger members of the cast should give the song a different flavor. I don’t expect “Tokimeki Un Deux Trois♪” to sound anything like the show’s battle music, and that is precisely why I think it could work.
The newly released visual apparently shows Nia, Hildetora, and Reliared enjoying a peaceful tea party. That’s almost comically different from the image of Nia charging toward some ridiculously powerful opponent because she desperately wants somebody capable of killing her.
And yes, that is a compliment.
The Cute Ending Is a Perfect Counterpoint to Nia’s Personality
One of the things that attracted me to the premise in the first place is how aggressively it plays against the standard isekai formula. Nia isn’t reincarnated because she wants a peaceful second life. She isn’t desperately trying to hide her previous identity either. She basically gets another chance at existence and immediately decides that she wants to find stronger enemies.
Her new body is the problem.
Nia Liston is a frail noble girl whose physical condition is so poor that her family is desperately searching for a solution. Then the soul of an undefeated warrior ends up inside that body, and suddenly the whole situation becomes much more chaotic. Instead of accepting her limitations, Nia starts using her experience and knowledge of martial techniques to overcome them.
That setup gives the anime two completely different sides. On one hand, there is violent fantasy action and ridiculous martial-arts ambition. On the other, there is the everyday life of a young noble girl surrounded by friends, family, servants, and academy life.
The ending theme appears to represent the second side.
I actually prefer this kind of contrast to having another generic serious ending with slow shots of the protagonist staring into the sunset. Let Nia be cute for three minutes after spending twenty minutes trying to find the strongest person in the room.
Tsunomaki Watame Is Handling the Opening
The musical lineup gets even more interesting because the ending is not the only major anime song announcement.
The opening theme, “Respawn!!”, will be performed by Hololive VTuber Tsunomaki Watame. That immediately gives the series a very different musical identity from what we’re getting with Magic Vision Girls Party.
The basic setup is easy to understand:
| Anime Song | Performer | Expected Tone |
|---|---|---|
| “Respawn!!” | Tsunomaki Watame | Energetic and action-focused |
| “Tokimeki Un Deux Trois♪” | Magic Vision Girls Party | Cute, upbeat and character-driven |
I like that division. An opening performed by Watame makes sense for a story built around reincarnation, combat and Nia constantly trying to push herself beyond her limits. Meanwhile, the ending can be the softer, sillier part of the package.
It also connects Nia Liston to two different corners of modern Japanese pop culture. Hololive brings in the massive VTuber audience, while the character unit gives fans another reason to become attached to the cast. From a marketing perspective, that is a pretty obvious strategy, but it doesn’t automatically make it a bad one.
The Story Is Still the Real Reason I’m Watching
As fun as the music announcements are, the premise remains the biggest selling point for me.
The original story began as a web novel on Shosetsuka ni Naro, running from 2019 to 2021. It later moved into commercial light novel publication under Hobby Japan’s HJ Bunko label. The series also received recognition through the HJ Shosetsu Taisho, which helped establish it before the anime adaptation.
The setup is straightforward enough to explain in a sentence, but the details are what make it entertaining.
Nia is essentially the reincarnation of a legendary warrior who reached the end of her life without ever finding the perfect opponent. She wanted to die in a glorious battle against someone who could genuinely defeat her. Instead, she dies peacefully and gets reincarnated into the body of a sickly noble girl.
Naturally, she is not happy about this.
Her new life becomes a bizarre combination of noble society, academy life, supernatural abilities and an almost unhealthy obsession with combat. Rather than treating her weak body as a permanent restriction, Nia works to eliminate the illness from within while rebuilding herself into someone capable of fighting again.
That gives the story a nice hook beyond the usual “I got reincarnated and became overpowered” setup. Nia was already overpowered mentally. Her problem is getting her new body to catch up.
The Cast Is Packed With Familiar Voices
The anime is also bringing together a pretty substantial cast. Alongside the three performers in Magic Vision Girls Party, viewers can expect:
- Fuka Izumi as Rinokis Funk
- Taku Yashiro as Anzel
- Yoko Hikasa as Fressa
- Satoshi Hino as Gandolf Rogen
- Koichi Sakaguchi as Bendelio
- Junichi Suwabe as Hyurence Altoire
- Maaya Uchida as Sharro White
- Kazuyuki Okitsu as Asuma
- Tomoyo Takayanagi as Neil Liston
- Yuki Urushiyama as Lynette Blanc
That’s a cast list that should give the adaptation plenty of vocal personality. Rina Hidaka, Yoko Hikasa, Satoshi Hino, Junichi Suwabe, and Maaya Uchida are especially recognizable names for longtime anime viewers.
The production is being led by Konami Animation, with Motoki Nakanishi directing and Gigaemon Ichikawa handling series composition and scripts. Yuki Ito and Kana Tasaoka are credited with character designs, while Naoki Endo is composing the music.
Two-Cour Run Makes Nia Liston More Interesting
Another detail that caught my attention is the planned consecutive two-cour broadcast. For a new light novel adaptation, getting enough room to tell its story over roughly half a year is significant.
I’ve become increasingly skeptical of fantasy anime that introduce a huge world, twenty characters and a mountain of lore before rushing through everything in twelve episodes. Nia Liston has a premise that could benefit from breathing room. The story needs time to establish Nia’s strange personality, her relationships and the rules of her new world before the bigger conflicts start taking over.
The trailers have also helped the series avoid looking like another completely disposable fantasy adaptation. The action footage has shown more energy than I initially expected, particularly in the choreography and movement. Obviously, a trailer is still a trailer, and the real test will come once the weekly episodes start airing.
Still, I understand why the two-cour announcement got fans talking.
When Does Nia Liston: The Merciless Maiden Premiere?
The anime is scheduled to premiere in Japan on October 6, 2026, making it one of the notable Fall 2026 anime releases. The Japanese broadcast is set to include Tokyo MX, with BS NTV and MBS also carrying the series.
International viewers will be able to watch the anime through HIDIVE, following Sentai Filmworks’ streaming arrangement.
That worldwide availability is particularly useful for a series like this because I suspect a lot of its audience will come from people discovering the premise through clips, anime communities and social media rather than from the original light novels.
My Take Before the Premiere
I’m not going to pretend that an adorable ending song automatically means Nia Liston: The Merciless Maiden will be great. Anime openings and endings can look fantastic while the actual show falls apart five episodes later. But I do think the music choices reveal something interesting about the adaptation’s intended personality.
“Respawn!!” gives the series its big energetic hook, while “Tokimeki Un Deux Trois♪” lets the characters be playful and cute. That feels appropriate for an anime where the protagonist can look like a delicate noble girl one minute and behave like a legendary warlord who has finally found another excuse to pick a fight the next.
The more I hear about this adaptation, the more curious I become. The reincarnation premise is unusual enough to stand out, the voice cast is strong, and the character-song ending could become one of those little seasonal anime songs that fans keep coming back to after the show ends.
For me, the real question is whether the anime can preserve the strange balance that makes Nia interesting in the first place. She shouldn’t become just another overpowered isekai heroine. The fun is that she is a battle-obsessed monster wearing the appearance of a fragile young noble girl.
If Konami Animation can maintain that personality while delivering the action promised by the trailers, I can absolutely see Nia Liston: The Merciless Maiden becoming one of those Fall 2026 shows that starts as a curiosity and ends up with a surprisingly loyal fanbase.
Nia might be looking for the person strong enough to defeat her. I’m just hoping the anime is strong enough to make me stick around for the entire two-cour journey.
