Sans:
It's a beautiful day outside
Birds are singing,
Flowers are blooming.
On days like these
Kids like you
Should be burning in [bad word] 

Chara:
One step left now
It's almost time,
Show you what my determination has still left for you to get back to.
You should prepare to just die.
Like all your friend you'll have a really good time.
(Sans:
Or else, friend, you're gonna have a bad time)

Sans:
But kids like you don't play by [bad word] 
And guys like me it ain't easy to be played for fools.
So let's go, let the room get chiller,
Let's go, dirty brother killer.
(Chara:
Let's go, just another killer)

Frisk:
Go ahead and just hit me since you're able,
We know my determination is unstable.
I'm not even mad because I keep on dying,
But I don't even know why I'm trying.

Sans:
You're not gonna win, we'll be here together
Fighting in this judgement hall forever.
And you just reset each time I beat ya,
But I'll always be right back here to meet ya.
I know you're made
Of
Love (x2)

Sans, Chara & Frisk:
Love (x3)

Frisk:
I know who you are,
You remember who I am.
We knew that once in a timeline
We had grown to be good friends.
And yet I killed your brother
Without giving him a chance,
Every time you throw me down
I hope you kill me once again.

Chara:
Go ahead kill me again, I see you're able,
But inside you know the end can't be evaded.
You think I might decide to stop if you stay patient,
But I am getting you with my determination.

Frisk:
This isn't what I want yet it's what I asked for,
Curiosity over all my morals,
I took away our perfect happy ending
Resetting the world, despite the warnings.
Right now I'm made
Of
Love (x2)

Sans, Chara & Frisk:
Love (x3)

Chara:
This is where it stops,
This is where it ends.

Sans:
If you want to get past me,
Well, you better try again.

Chara:
But even if I hear you
I won't give up my attack.

Sans:
Do you just like the feeling
Of your sins crawling on your back?

Frisk:
So go ahead and hit me since you're able,
All the sin that I can feel is unbearable.
If I could only hit you once it would be over,
But the consequences last forever.

Chara:
Why not let me win? You can't dodge forever.
Even if the pain is more fun together.
You know I will just reset [bad word] back newer
And with every try I'm getting even faster that you are.
I am made
Of
Love (x2)

Sans, Chara & Frisk:
Love (x3)

Sans:
This is where it stops,
This is where it ends.

Chara:
You keep telling me those words and hope
That I would understand.

Sans:
But no matter how I stall you,
You don't give up your attack.

Chara:
Can you just not see the [bad word] 
Or can you not see what this all meant?

Sans:
Go ahead and try to hit me if you're able,
You should know by now the mercy's off the table.
Think that you can try to spare me like I'm some pawn?
Well, you didn't spare my brother so get dunked on.

Frisk:
The flowers are in bloom
And the birds will tell
It's a beautiful day
To be burning in [bad word] 
You gave my advice...

Chara:
You should be dying...

Sans:
I am determination.
I know you're made...
(Chara:
I'm enterily made...

Frisk:
I am made)

Sans, Chara & Frisk:
Of
Love (x2)

Sans:
But I think I'm stronger than you...
(Chara:
And I'm sure I'm stronger than you...

Frisk:
But I'll give up for you)

Sans, Chara & Frisk:
Love (x3)

Chara:
I am stronger than you.

Sans, Chara & Frisk:
Love (x3)

Frisk:
But I'll give up for you.

Chara & Frisk:
Love (x3)

Sans: [bad word] on now kid,
You and me together, [bad word] and let's see
Which of us is better.
I guarantee
That for your endeavor
I'll see it end
Here and now.

So in this fight
You are going to pay
For the lives lost
All those that you have slain.
 [bad word] here kid
Because it is day that
You will now know
The [bad word] meaning of
Pain.
