One of the most haunting and beautiful moments in Chainsaw Man: The Movie – Reze Arc is the scene where Reze quietly sings in Russian while strangling an assassin.
The soft melody and her gentle voice clash with the brutal violence on screen, leaving many fans wondering:
What is that song? Is it a real Russian song? What does it mean for Reze?
This article breaks down the origin of the song, the rumors around it, and what creator Tatsuki Fujimoto officially revealed about its true meaning.

Is Reze’s Russian Song a Real Song?
Surprisingly, no.
After a lot of research by fans, it seems that the song Reze sings does not actually exist in Russia.
There is no record of a traditional or modern Russian song with the same melody or lyrics.
Instead, the song appears to be an original piece created specifically for Chainsaw Man and for Reze’s character.

The Rumor: A Connection to Dearest Mary Jane (1994)
For a while, some Japanese fans believed the song might have been inspired by Betty Neels’ 1994 romance novel Dearest Mary Jane.
In the novel:
- Mary Jane loses her parents at a young age and grows up with her beautiful sister, Felicity.
- Felicity becomes a glamorous model, while Mary Jane quietly runs a small café.
- When Mary Jane meets a kind doctor named Sir Thomas, she falls in love with him…
- …but he ends up falling for her sister instead.
Because of the book’s gentle tone and themes of quiet love, loneliness, and heartbreak, fans speculated that it could be the “source” of Reze’s song and the character “Jane.”
However, this remains only a fan theory.
There is no official evidence that directly connects Dearest Mary Jane to Reze’s song.
The Truth from Tatsuki Fujimoto

The real answer comes from Tatsuki Fujimoto himself.
According to the official guidebook that was distributed in Japanese theaters with the release of Chainsaw Man: The Movie – Reze Arc, Fujimoto explained the meaning of the song this way:
“It’s just a song about an ordinary date.
At the end, the person sleeps in a church — it’s about wanting to live and die like a normal person.”
The title of the song is:
“Jane Slept in the Church.”
This confirms two important things:
- The song is an original piece, not a pre-existing Russian song.
- The lyrics are all about an ordinary, peaceful date – the kind of life Reze secretly wishes she could have.

Why Does Reze Sing It While Killing?

Reze’s quiet singing during such a violent scene perfectly shows her inner conflict.
On one hand, she dreams of living a peaceful, normal life:
going on dates, drinking coffee at cafés, laughing with Denji, and doing cute, ordinary things.
On the other hand, she is a trained assassin and a bomb hybrid, raised as a weapon and forced to kill to survive.
By having her sing a gentle “date song” while taking someone’s life, Fujimoto highlights this tragic duality:
- Reze is both human and weapon.
- Both lover and killer.
- Someone who longs for warmth, but is trapped in a violent world.
The fact that she sings in Russian adds another layer.
It reminds us of her origins and the cold, distant environment she comes from.
Her song almost becomes a quiet prayer — a wish to live like a normal girl, even if only for a moment.

The Song, the Flower, and Reze’s Humanity

In the film, Reze also receives a red gerbera flower.
Red gerberas can symbolize:
- Passion and courage
- Mystery
- A “new beginning” or “first step into a new life”
In flower language, a single gerbera can mean things like:
- “You are my destined one”
- “Love at first sight”
Together, the song and the flower beautifully represent Reze’s deepest wish:
to take that first step into a peaceful, ordinary life with Denji —
a future that will always stay just out of reach for her.

Full Lyrics: “Jane Slept in the Church”
Below are the Russian lyrics as heard in the movie, along with the English translation:
Jane Slept in the Church
(Song sung by Reze – Chainsaw Man: Reze Arc)
День моего свидания с Джейн
All is ready for my date with Jane
Утром мы пойдем вместе в церковь
In the morning, we’ll go to the church together
Мы будем пить кофе и есть омлеты в кафе
Let’s drink coffee and eat omelets at a café
После того как мы прогуляемся в парке
After that, we’ll take a walk in the park
Мы пойдем в аквариум и увидe любимых Джейн, дельфинов и пингвинов
Then we’ll visit the aquarium and see your favorites, Jane — the dolphins and the penguins
После обеда мы отдохнем
After lunch, we’ll take a little rest
Итак, что мы сделали утром?
So, what did we do this morning?
Мы будем говорить об этом пока не вспомним
Let’s talk about it until we remember
Мы не вспомним
We won’t remember
И ночью мы будем спать в церкви
And at night, we’ll sleep in the church
Why This Song Makes Reze Unforgettable
“Jane Slept in the Church” is not a traditional Russian folk song —
it’s an original creation by Tatsuki Fujimoto that captures everything about Reze:
- Her warmth and kindness
- Her role as a weapon and assassin
- Her impossible dream of being just a normal girl
That’s why this quiet little song, sung in the middle of a murder, hits so hard.
It’s Reze’s heart, hidden inside a lullaby for a life she can never really have.
