if this poem good? ?

butler in black
a dark, dark soul
that is, if within him
there is one at all
young master he serves
till vengeance is dealt
“sebastian! ”
he is called
by the master he serves
to do his bidding at all hours

he must always oblige
the child who bids him work
whatever is ordered,
he shall complete
any competition
shall fall to its knees

butler in black
will never hold back
“i’m one hell of a butler,”
yeah, sebastian, we know that!

his young master
a happy boy until the night of the fire
parents gone,
he was taken
branded
and tortured as on enslaved
until by his own desperate desire
he summoned a demon to grant his wish
the demon said, “you know what i want in return for this right? ”
“tch, i am a phantomhive,
i walk in the darkness, not in light
take my soul, i don’t want it.
but i will have my revenge,
but with you by my side,
my parent’s death,
i will avenge,” the young master said.
