Fanfiction Poetry: Equivalent Exchange (Fullmetal Alchemist)

Father ran,
Mother dead,
Who’s left?

One mistake,
One failure,
Another loved one lost.

One is all,
All is one,
But I’m only half.

Life for life,
Blood for blood,
Debt repaid.

A bound soul,
His weak brother,
Mere humans.

My arm,
My leg,
My heart.

Nothing I won’t give.

My brother…

You’re all I have.
