Samael, of Time and Space,

Can take an hour to wash his face

And so, when he is feeling nice,

He'll use the same half-hour twice.

He doesn't feel that nice a lot

And, normally, his bathroom slot

Will last from ten past six to eight

And make his little brothers late.

oooooo

Lucifer, the King of Light,

Thinks second place is his in right

And so, from eight to nine o'clock,

He locks the very faulty lock

And gets a daily one hour lease

To have his morning wash in peace.

oooooo

Azazel, King of Spirits, third,

Will hurry in without a word,

Take barely any time at all,

Then rush back out into the hall

As if his tail has caught on fire

(He works a day job in Assiah).

oooooo

Egyn next: the King of Water,

Red from early-morning slaughter,

Nine fifteen to half past ten

Will lock the bathroom door (again)

And use up in his given hour

The last hot water in the shower.

oooooo

Iblis next; the Fire King,

Who sets his bedside clock to ring

At half past ten exactly so

That when the bathroom's his he'll know.

He leaves exactly twenty past;

The change before and after vast.

oooooo

King of Insects, Beelzebub,

Takes long enough within the tub

But when you add 'collecting' too,

(For Beelzy owns an insect zoo)

It's a wonder he comes out

(At twelve o'clock or thereabout).

oooooo

Astaroth, the King of Rot,

Tries not to waste the time he's got

So he is fastest at the sink

(He only stops to have a drink

And comb his hair and then he's gone)

He sometimes leaves the tap turned on.

oooooo

And last, Amaimon, King of Earth,

Who gives the room the widest berth

And spends as long as he can wait

In PJs and a rumpled state

And, when his older bros protest,

He'll skip the wash and go get dressed.

oooooo

A/N. For those who only know American English, 'tap' is 'faucet'. And, apparently, (I only found out through Fanfiction anyway) Mephisto Pheles' demon name is Samael.

All the demons listed above are correct according to the manga: I looked in the back section with the 'Hobgoblin, kin of Amaimon, King of Earth' things.
