by The autumn 2026 anime season has introduced a rather unusual series, FX Fighter Kurumi-chan (FX Senshi Kurumi-chan), a comedy-drama about young women navigating the unpredictable world of foreign exchange trading. Along with its distinctive story, the anime has attracted attention for its catchy opening and ending themes, both performed by voice actress Aina Suzuki, who plays the main character, Kurumi Fukuga.
The opening theme, also titled “FX Fighter Kurumi-chan,” is an energetic character song that reflects the series’ unusual combination of cute characters and high-risk financial decisions. The ending theme, “$・¥・€” (Dollar, Yen, Euro), takes a playful approach to the world of international currencies.
Both tracks became available on digital music platforms on October 2, 2026, one day after the television anime began airing in Japan. The opening theme has also received a live-action music video featuring comedians Yoichi Okano and Mogura Suzuki. Its surreal visuals and memorable dance sequence have attracted considerable attention online.
This article covers the complete FX Fighter Kurumi-chan anime theme song list, including the opening and ending tracks, their creators, Aina Suzuki’s music career, and the latest promotional updates.
What Is the Anime FX Fighter Kurumi-chan About?
FX Fighter Kurumi-chan is based on the manga written by Demunyan and illustrated by Daisuki Tansan. It is serialized in KADOKAWA’s Monthly Comic Flapper magazine.
The story follows Fukuga Kurumi, a university student who enters the world of foreign exchange trading, commonly known as FX, with an unusual personal goal: recovering the 20 million yen her late mother lost through trading.
Kurumi first learns about her mother’s enormous financial losses when she is still a middle-school student. She keeps the situation secret from her father, fearing that the discovery could tear the family apart. Determined to understand what happened and eventually recover the lost money, she begins studying the world of currency trading.
Years later, when she becomes a university student, Kurumi finally starts trading FX herself.
However, the financial market is far more complicated than she imagined. Currency prices can rise and fall rapidly, and even a seemingly promising decision can result in enormous losses. As Kurumi experiences the excitement and anxiety of trading, she encounters other women with their own personalities, ambitions, and complicated relationships with money.
The result is a story that mixes comedy, drama, and financial themes. Its characters may look cute, but the situations they face can become surprisingly stressful and dangerous.
What Does FX Mean?
FX stands for foreign exchange. It refers to trading one currency against another in an attempt to profit from changes in their exchange rates.
For example, a trader might buy US dollars using Japanese yen if they believe the dollar will become more valuable compared with the yen. If the exchange rate moves in the expected direction, the trader may make a profit. If it moves in the opposite direction, they can lose money.
FX trading often involves leverage, which allows traders to control a larger position than the money they initially deposit. Although leverage can increase potential profits, it can also magnify losses.
The anime uses these financial concepts as part of its dramatic storytelling. Terms such as margin calls, unrealized losses, and forced liquidation help communicate the pressure that Kurumi and the other characters experience.
The animation is produced by Passione, the studio known for titles including Higurashi: When They Cry – Gou. The series features music by Takuro Iga, who has also worked on the soundtrack for Oshi no Ko.
The television anime premiered in Japan on October 1, 2026.
Opening Theme: “FX Fighter Kurumi-chan”
Song: “FX Fighter Kurumi-chan”
Artist: Kurumi Fukuga (CV: Aina Suzuki)
Lyrics: Hitoshi Hayata, Takuya Sakai, Yuya Denda, and Kyohei Yamamoto
Composition: Takuya Sakai, Yuya Denda, Hitoshi Hayata, and Kyohei Yamamoto
Arrangement: Yuya Denda and Takuya Sakai
Digital Release: October 2, 2026
The opening theme of FX Fighter Kurumi-chan is also titled “FX Fighter Kurumi-chan.” It is performed by Aina Suzuki under the character name Kurumi Fukuga (CV: Aina Suzuki).
Rather than using Suzuki’s individual artist name, the song is officially credited to the fictional character she portrays. This makes the track a character song, meaning that it is performed by a voice actor in the name and identity of their anime character.
Suzuki expressed her happiness about being selected to sing the opening theme. In a post on X, she said that she was delighted to perform the song as Kurumi and described it as a catchy denpa-style track that listeners would want to hear repeatedly.
A denpa song is a Japanese pop-culture music style often associated with unusual lyrics, playful sounds, exaggerated energy, and memorable melodies. The opening’s distinctive musical approach fits the anime’s quirky atmosphere.
The song was created by a four-person team: Hitoshi Hayata, Takuya Sakai, Yuya Denda, and Kyohei Yamamoto. Yuya Denda and Takuya Sakai handled the arrangement.
Denda also described the track as a socially conscious song that vividly portrays both the appeal and reality of FX trading. This is an interesting way to approach the opening: beneath its energetic presentation, the song is connected to a story about financial risk and the emotional pressure of making trading decisions.
Creditless Opening Video Surpasses One Million Views
The anime’s creditless opening video was released on YouTube on October 1, 2026, around the television premiere. It features the opening song without the usual production credits appearing over the animation.
The video surpassed one million views in approximately ten days, demonstrating the interest generated by the song and the series’ unusual concept.
A creditless opening is a version of an anime’s opening sequence without the names of the production staff and other credits displayed on screen. These videos are commonly released on official anime channels so viewers can enjoy the animation and music without text covering the visuals.
The opening sequence combines the show’s characters with energetic imagery that reflects the excitement and uncertainty of currency trading.
Live-Action Music Video Features Yoichi Okano and Mogura Suzuki
The opening theme received another promotional release in the form of a live-action music video. Unlike the animated opening sequence, this video features comedians Yoichi Okano and Mogura Suzuki from the comedy duo Kuuki Kaidan.
The music video begins with the two men involved in FX trading, but the situation quickly becomes increasingly surreal. They are transported into space, encounter aliens, and find themselves caught up in an unpredictable adventure.
One of its most memorable moments features the comedians dancing to the lyrics associated with a margin call. The dance has attracted attention under the name “Margin Call Dance” (also referred to as the margin-call dance).
The video deliberately mixes financial terminology with absurd comedy, creating a visual style that matches the unusual personality of the anime.
Kyohei Yamamoto, who participated in creating the opening song, praised the music video for its chaotic and entertaining atmosphere.
Aina Suzuki also shared her reaction, mentioning the scene in which Okano and Mogura smile and spin their arms around. She felt that the strange visual style matched the energetic denpa character of the song.
The live-action video gives the opening theme an identity beyond the anime itself, combining music, comedy, and a playful interpretation of FX trading.

- Yoshi – Don’t Toy with Me, Miss Nagatoro
- Rina Shioi – Magical Girl Site

Her performance as Kurumi Fukuga in FX Fighter Kurumi-chan gives her another opportunity to combine voice acting and singing. Since both theme songs are performed in character, listeners can enjoy them as part of Kurumi’s fictional musical identity.
Ending Theme: “$・¥・€” (Dollar, Yen, Euro)
Song: “$・¥・€”
Pronunciation: Dollar, Yen, Euro
Artist: Kurumi Fukuga (CV: Aina Suzuki)
Lyrics and Composition: Hitoshi Hayata
Arrangement: Ginnojo Hoshi
Digital Release: October 2, 2026
The ending theme of FX Fighter Kurumi-chan is titled “$・¥・€”, pronounced “Dollar, Yen, Euro.” Like the opening, it is performed by Aina Suzuki under the character name Kurumi Fukuga.
While the opening theme introduces the anime with energetic music and a memorable melody, the ending takes a different approach. Its title itself references three familiar currency symbols: the US dollar ($), the Japanese yen (¥), and the euro (€).
The song’s lyrics also include the names of currencies from around the world, making its central theme immediately recognizable. Hitoshi Hayata handled both the lyrics and composition, while Ginnojo Hoshi arranged the track.
Suzuki described the ending as a cute and heartwarming dollar-yen-euro song in her post on X.
Hayata also joked that listeners would become knowledgeable about currencies from around the world after hearing the song. The playful comment reflects the track’s unusual subject matter and its connection to the anime’s financial theme.
The ending song became available on music-streaming platforms on October 2, 2026, alongside the opening theme.
Creditless Ending Video and Fan Reactions
The official creditless ending video was released on October 1, 2026, through the anime’s YouTube channel.
Unlike the opening’s live-action music video, the ending video uses the anime’s own visual style. It allows viewers to enjoy the ending sequence without production credits appearing over the animation.
The song’s unusual lyrics have also become a talking point among viewers. Some fans have jokingly described it as a song that mentions currencies so frequently that it feels like a musical introduction to international money.
Other comments have praised its originality and playful contrast with the more serious subject of the series.
The ending theme demonstrates how the production uses music to reinforce the anime’s central concept. Rather than choosing a conventional romantic or emotional ending song, the creators have built a track around the world of currencies and trading.
Latest Update: FX Fighter Kurumi-chan Opening Gets a Death-Voice Cover
On November 3, 2026, a new musical promotional video related to the opening theme was announced.
Voice trainer MAHONE released a death-voice cover of “FX Fighter Kurumi-chan” under the title “Death-Voice Fighter MAHONE-chan.” The project also includes a separate reaction and explanation video in which MAHONE discusses the song from a vocal-training perspective.
Death vocals are a singing technique associated with extreme vocal styles, often involving harsh, growling, or distorted sounds. The cover offers a very different interpretation of the original character song.
MAHONE is a voice trainer who operates the MyScream vocal-training school, which offers instruction in techniques including death vocals and whistle vocals.
This new version adds another unusual musical spin-off to the anime’s growing collection of promotional content. It also shows how the opening theme can be reinterpreted in styles far removed from Aina Suzuki’s original performance.
The theme songs of FX Fighter Kurumi-chan are an important part of the anime’s identity. Having Aina Suzuki perform both tracks as the main character creates a consistent connection between the music and Kurumi’s personality.
The opening theme, “FX Fighter Kurumi-chan,” has gained attention through its creditless anime sequence and its unusual live-action music video featuring Yoichi Okano and Mogura Suzuki. Meanwhile, the ending theme, “$・¥・€,” stands out for its currency-focused lyrics and playful concept.
The November 3 release of MAHONE’s death-voice cover adds another interesting development to the music promotion.
For anime fans who enjoy distinctive character songs, unusual music videos, and memorable opening and ending themes, FX Fighter Kurumi-chan offers something different from the usual anime soundtrack. Both official songs are available on digital music platforms, making it easy to listen to Kurumi’s musical introduction and ending outside the television series.
