If you’ve spent any time in the anime community over the last few years, you’ve heard it. That bassline. It’s infectious. It starts with a steady, rhythmic pulse that feels almost like a heartbeat before the jazz-fusion elements kick in. We’re talking about the Bunny Girl Senpai ending song, officially titled Fukashigi no Karte (Mysterious Chart). Honestly, it is rare for an ending theme to become more iconic than the opening, but here we are.
Most shows treat the ED as a bathroom break. You skip it to get to the "Next Episode" button. Not this one. There is something fundamentally haunting about how the song reflects the Puberty Syndrome arcs of the characters. It doesn’t just play; it evolves.
The Bunny Girl Senpai Ending Song is Actually Six Different Songs
Variety matters. Usually, a production committee hires a band, records one track, and slaps it onto every episode. Rascal Does Not Dream of Bunny Girl Senpai took a different path. They used the same composition but changed the vocalists to match the current arc’s protagonist.
It starts with Mai Sakurajima (voiced by Asami Seto). Then it shifts to Tomoe Koga, Rio Futaba, Nodoka Toyohama, Kaede Azusagawa, and finally Shoko Makinohara. By the time you get to the final episode of the first season, you hear all six of them singing together. It’s a literal representation of Sakuta’s growing circle of friends and the emotional weight he’s carrying.
The lyrics were penned by Saori Kodama, with composition and arrangement by the hideakira (fox_capture_plan). This wasn't just a pop song. It was a deliberate piece of storytelling. If you listen closely to the solo versions, the tone changes. Mai’s version feels mature and slightly aloof. Kaede’s version? It’s heartbreakingly innocent, especially when you consider what happens to her memories toward the end of the series.
Why the Jazz-Fusion Sound Works for Puberty Syndrome
Physics is weird. The show uses "Puberty Syndrome" as a metaphor for quantum mechanics—Schrödinger's cat, Laplace's Demon, and the Observer Effect. It makes sense that the Bunny Girl Senpai ending song would sound equally complex. It uses a 4/4 time signature but the syncopation in the bass and the piano flourishes give it a "city pop" meets modern jazz vibe.
It feels sophisticated.
Most anime about high schoolers use high-energy J-Rock or bubblegum J-Pop. This show deals with existential dread. It deals with people literally disappearing because society stops acknowledging them. The melancholy in the melody captures that loneliness perfectly. You’re sitting there, staring at the screen after a heavy emotional beat, and that bass hits. It grounds you. It tells you that while things are weird, they are also beautiful.

The song’s title, Fukashigi no Karte, translates to something like "Mysterious Medical Chart." It treats the characters' emotional trauma as a condition to be diagnosed and understood. It’s clinical yet deeply emotional.
The Visual Evolution You Might Have Missed
The animation for the ED is a masterclass in "less is more." It features the female lead of the current arc walking along a beach. The waves lap at the shore. The sun sets or the moon rises.
Simple, right? Not really.
The beach is the Shichirigahama shore in Enoshima. This is a real place. Fans go there on "anime pilgrimages" all the time now. The lighting in the animation changes depending on the mood of the story. In the Rascal Does Not Dream of a Dreaming Girl movie, the ending sequence takes on an even more somber tone because of the high stakes involving Shoko and Sakuta’s heart.
The walking animation is rhythmic. It matches the BPM of the song. It creates a hypnotic effect that makes it very hard to look away. You’re watching these girls walk toward an uncertain future, which is basically the entire theme of the show.
Breaking Down the Impact of fox_capture_plan
We need to talk about the composers. Fox_capture_plan isn't your typical anime music factory. They are an instrumental three-piece band known for "Contemporary Jazz Rock." They bring a level of technical proficiency that you usually only find in bebop clubs.
The piano work in the Bunny Girl Senpai ending song is particularly dense. There are these little chromatic runs that happen in the background that most people miss on the first listen. It’s those details that make the song "rank" so high in people's playlists years later. It doesn't get old because there's always a new layer to hear.

Compare this to the opening theme, Kimi no Sei by the peggies. The opening is great—it’s high energy, catchy, and frantic. It represents the "chaos" of Puberty Syndrome. But the ending song? That’s the "aftermath." It’s the reflection. It’s the part where Sakuta (and the viewer) has to process the weirdness of the world.
Common Misconceptions About the Vocals
A lot of people think the "All Stars" version (where everyone sings) is the only version that exists.
Actually, the individual solo versions are often harder to find on mainstream streaming platforms unless you're looking for the specific character albums or the "Selection Album" released by Aniplex. Each seiyuu (voice actor) brought their character’s personality into the booth.
- Asami Seto (Mai): Strong, stable, leading.
- Nao Toyama (Koga): A bit more "idol" like, reflecting her desire to be popular.
- Atsumi Tanezaki (Futaba): Muted, logical, slightly hesitant.
- Maaya Uchida (Nodoka): Vibrant but with an underlying edge.
- Yurika Kubo (Kaede): Soft, breathy, and fragile.
- Inori Minase (Shoko): Ethereal and mysterious.
The way these voices blend in the final version is a technical feat. Mixing six different vocal timbres without it sounding like a muddy mess requires a very talented sound engineer.
The Cultural Longevity of Fukashigi no Karte
Why is we still talking about this song in 2026?
TikTok. YouTube loops. Lo-fi remixes.
The song became a "vibe." It transcended the anime. You’ll find 10-hour loops of the bassline on YouTube with millions of views. It’s used in "POV" videos and aesthetic edits. It has that rare quality of being "cool" even to people who haven't seen the show.

But for those who have seen it, the song is a trigger for "Post-Anime Depression Syndrome." You hear the first three seconds and you immediately think of the "Kaede incident" or Sakuta running through the streets crying. It’s a powerful emotional anchor.
The song reached the top of the Oricon charts and Billboard Japan’s animation charts during its release window, which is impressive for an ending theme. Most people forget the ED. Not this time.
How to Experience the Best Version of the Song
If you really want to appreciate the Bunny Girl Senpai ending song, you have to listen to it on a decent pair of headphones. The low-end frequencies are the star of the show. If you’re listening through phone speakers, you’re missing 40% of the music.
The bass isn't just keeping time. It’s playing a melody of its own. It’s a "walking bass" style that feels like it’s literally walking along the beach with the characters.
The movie version (Dreaming Girl) adds orchestral swells that make it feel cinematic. If you haven't heard that specific arrangement, find it. It turns a jazz track into a grand finale.
Final Insights for Fans
The ending song isn't just a credits roll. It is a narrative tool. It tracks the growth of the cast. It provides a bridge between the supernatural mystery of the plot and the grounded reality of the characters' emotions.
Next time you watch, don't skip. Listen to the subtle differences between the episodes. Pay attention to who is singing and how their voice reflects their current state of mind. It’s one of the few times in modern anime where the music is just as smart as the writing.
Practical Next Steps for Fans:
- Hunt for the Solo Versions: Look for the Rascal Does Not Dream of Bunny Girl Senpai Original Soundtrack or the specific character song CDs to hear the nuance in each girl's performance.
- Check the Lyrics: Read the English translations of Fukashigi no Karte. The lyrics about "not being able to see my own heart" directly parallel the invisibility Mai experiences in the first arc.
- Explore fox_capture_plan: If you like the sound, check out the band's other albums like WALL or BUTTERFLY. You'll find that same high-level jazz-fusion energy.
- Visit the Shore: If you ever visit Japan, the Enoshima coastline is exactly as it looks in the ED. Put the song on your headphones and walk the beach at sunset for the ultimate experience.
