Lyrics:

When the light is running low
And the shadows start to grow
And the places that you know
Seem like fantasy

There's a light inside your soul
That's still shining in the cold
With the truth
The promise in our hearts


Long ago, the tale goes
From myths and legends and fear they rose
A world basked in the purest light
Beneath it grew eternal night

When the future lost its rights
Three heroes will dive into the night
It was a tale of light and dark
To the worlds' edge they shall embark


The fountains freed
The roaring cries
The balance starts
to shift

Get up, out of bed
Raise up your bat and
Join the fight


When the dark begins to grow
And the stars no longer show
Lost deep in an endless night
And nothing seems right

When the sky begins to grey
And the dark has found its prey
Face the KNIGHT
Which makes with blackened knife

When the light is running low
And the shadows start to grow
And the places that you know
Seem like fantasy

There's a light inside your soul
That's still shining in the cold
With the truth
The promise in our hearts

Don't forget
I'm with you in the dark


With hope crossed on their hearts
All alone in the deepest darkest
Deep, deep inside a light shines bright,
eclipsing the night

Demon heart is crying
As our heroes keep fighting
They'll hear the ring of heaven's call
They'll see the tail of hell take crawl


The roaring sings
a lullaby
Of nightmares
and despair

But they will persist
Not all is lost
Their hearts are crossed


As the sunlight starts to fade
And the shadows start to wake
And as your thoughts are not all
That they seem to be

There's a legend whispered on
Heroes standing at new dawn
Standing tall
And seeing past the dark

And when the stormy clouds are near
And it becomes too much to bear
Struck with fear, right through the chest
As all hope seems lost

They're the ones who carry on
Fight the dark that you run from
Staying true
With courage in their hearts

In the dark
With your heart as the ark


IT STARTED ONCE UPON A TIME

A LEGEND SPOKE IN SHADOWD RHYME

OF LIGHT AND DARK AND LOVE AND HATE

THE HOPES AND DREAMS THAT GOVERN FATE


As the fountains fill the sky
When the darkened eyes will cry
There's a place high in the sky
That's so far away

When the nightmare has been freed
With the shadows cutting deep
It's the end
The prophecy is told

( DELTARUNE )


When the day begins to break
And the shadows start to fade
When all hope returns and
it's gonna be okay

Shattered dreams and all that's gone
Like a king, not as a pawn
Life's a game
Get up and try again

When the dark is kept at bay
And the light may find its way
Fighting fear, dread, and despair
Bringing nightmare's end

Through the fields of pink and gold
Persevering in the cold
As the air
crackles with freedom


When the light is running low
And the shadows start to grow
All your friends are here with you
in your memories

All our Hopes and Dreams live on
Seal the fear that you ran from
Standing tall
Breaking through the clouds

So when you think you lost your way
There's no need to feel so grey
Bursting bright, and crying out
Scream it loud and proud

You're the legend they foretold
SAVE the World and staying gold
Fighting fate
The tale of DELTARUNE

Follow me through the dark
With your heart as my ark

But don't ever forget
Fade into the sunset

I'm with you in the dark

Artist commentary for デルタルーン:

ruby:

I originally intended to touch up an old remix of the DELTARUNE main theme I had done back in 2022.

Then, the DELTARUNE Nintendo Switch 2 trailer dropped, which used an arranged version of the piano demo. I've always been a huge fan of the main theme demo, and a little disappointed it never made it past the demo stage, so hearing a more produced version for THE DELTARUNE release date trailer, it definitely gave me some feelings.

So, instead of including an old remix, I re-transcribed the song, including the additional strings and EarthBound piano.

(someone bug me whenever this commentary makes it onto the wiki, I can include some wips and screenshots.)

at some point, I decided to increase the tempo, add guitars, basically make it way more J-Rock-like. I really liked how it sounded so I kept working on it.
I decided I wanted to make it a full-lenght song, and even write lyrics for it. Great ideas, but let's first try to finish a demo.

I had the full structure in my head, I knew I wanted to use the lyrics of Don't Forget. then, I knew I wanted to have cool imagery in the lyrics, some lyric concepts I wrote down in the moment made it to the final song even!

I really had a concrete vision, at the time I literally said:
"I can't stop thinking about it, all I know is i have to make this song a reality. now I know how Toby felt after his fever dream, but I was awake when I conjured this concept. I need to make it.........."

After Chapters 3+4 released, I did end up updating the bridge section to include the GUARDIAN melody. Before, the bridge always felt like it was missing something. The overall arrangement was done, I could focus on writing guitar parts, and mixing.

I'm not a guitarist, but I tried to make it realistic, something Jun Senoue-like or something.

As the lyrics were slowly reaching completion (there were a lot of lines where I couldn't think of anything and they only really came together last minute lol), Jebb was just like:

"Ok but consider
Miku for vocals.
Or teto."

now, I hadn't done much vocaloid or synthv stuff before, I had only played with Miku a bit earlier this year, but it was the perfect suggestion. I also had been listening to some Jamie Paige music with my partner, specifically Constant Companions, which has Teto on various tracks. so, I decided I would just try it...

and it... worked!

so the last month of working on this song was me finishing the guitars, finishing the lyrics, and programming Teto.

that's awesome and everything, I am very proud of what I managed to achieve with this song. there are parts of the production I think are lacking, but considering I also had to put time into stuff like writing lyrics, I think it was a fair trade-off.

maybe some day I will make a version with live vocals, or maybe guitar or something... that'd be cool!

despite all this, I still didn't have a title. I just called it the "deltarune anime opening", which isn't really a satisfying title for a track with this much effort lol.

so then I saw the final art by SelanPike, which said it...

デルタルーン

it's just the Japanese name for deltarune, but that's just perfect for a hypothetical anime opening for the game, so I adopted it as track title too.

I really hope you enjoy the track! and, if you read through all this, I hope this was a neat insight into the song's creation!

PS as the title is デルタルーン, if you want to translate or "localize" it to English... as it's just the Japanese name for the game, it's just "DELTARUNE" lol

Selan Pike:

Originally I was going to do the usual jokey UwU school anime thing, but the more I looked through inspo images, the more I wanted to base it on 90's fantasy anime. In the end, I based this image heavily on a specific manga illustration from Magic Knight Rayearth, which was a huge inspiration to me when I was a kid.
