(This poem will describe all of the characters, like the "delinquents and slobs").
Rose are red,
violets are blue,
don't get in my way,
or you'll end up dead, too,
I seemed so innocent and
calm like a lamb,
and not even a genius could discover who I am.

Delinquents and slobs can't stop me now,
he WILL love me, and I'll show him now,
losers and loudmouths,
creeps and kissups,
it seems I have a minor hiccup.

And finally, my time has come,
to rid this city of Senpai-stealing scum,
roses are red,
violets are blue,
don't get in my way,
or I'll slit your throat, too.
