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] 

Frisk:
I don't know what I got into
Somehow I can't go back even if I really wanted to
So what more can I do?
Here in the end it's just me and you

Chara:
But guys like you are always just fools [bad word] at me, try to kill me with your fancy tools
Let's go, now the room gets chiller
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.
I know you reset each time I beat ya',
But I'll always be right back here to meet ya'.

(At once)
Frisk: Right now I'm made
Chara: I am made
Sans: I know you're made
OF LOVE

Sans: Heheheheh

Chara:
''This is where it stops, this is where it ends''
You keep telling me these words and hope I'll understand

Sans:
But no matter how I stall you,
You don't give up your attack.
Do you just like the feeling
Of your sins CRAWLING on your back?

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'm getting you with my DETERMINATION

Frisk:
The flowers are in bloom as the birds will tell
It's a beautiful day to be burning in [bad word] 
You gave me advice, I chose Genocide,
But I know how to make it right

(At once)
Frisk: Right now I'm made
Chara: I'm entirely made
Sans: I know you're made
OF LOVE

(At once)
Frisk: But I'll give up for you
Chara: But I'm STRONGER than YOU
Sans: But I think I'm stronger than you

(At once, without Sans)
LOVE
Frisk: But I'll give up for you
Chara: But I'm STRONGER than YOU
LOVE

Frisk: But I'll give up for you
Frisk and Chara: LOVE

Chara: LOVE
