She flips through songs in the internal jukebox that is her brain and decides on unconventional.

Her voice is a soft croon and if you can imagine her putting her girls to bed with this lullaby, it's for a reason (skipping a verse or two).

"There's a monster that lives 'neath your bed.
Oh for crying out loud it's a futon on the floor,
he must be flat as a board

There's a creature that lurks behind the door,
though I've checked there fifteen times
when I leave then he arrives
every night.

Tell the monster that lives 'neath your bed
to go somewhere else instead
or you'll kick him in the head

Tell the creature that lurks behind the door
if he knows what's good he won't come here no more
'cause you're kicking his butt at the count of four.

Goodnight demon slayer, goodnight.
Now it's time to close your tired eyes.
There are devils to slay and dragons to ride,
if they see you coming, oh they better hide.

Goodnight, goodnight, goodnight.
Goodnight my little slayer goodnight.

Tell the monster that eats children, that you taste bad
and you're sure you'd be the worst he's ever had.
If he eats you, don't you fret, just cut him open with an axe.
Don't regret it, he deserved it, he's a cad.

Tell the harpies that land on your bed post
that at the count of five you'll roast them alive.
Tell the devil it's time you gave him his due
he should go back to hell, he should shake in his shoes
'cause the mightiest, scariest, creature is you.

Goodnight demon slayer, goodnight.
Now it's time to close your tired eyes.
There's devils to slay and dragons to ride,
if they see you coming, oh they better hide.

Goodnight, goodnight, goodnight.
Goodnight my little slayer goodnight.

I won't tell you, there's nothing 'neath your bed.
I won't sell you, that it's all in your head.
This world of ours is not as it seems;
the monsters are real but they're not in your dreams.
Learn what you can from the beasts you defeat,
you'll need it for some of the people you meet.

Goodnight demon slayer, goodnight.
Now its time to close your tired eyes.
There are devils to slay and dragons to ride,
if they see you coming, oh they better hide.

Goodnight, goodnight, goodnight.
Goodnight my little slayer goodnight.

Goodnight, goodnight, goodnight.
Goodnight."
