Weapon Story[]

The shield left hanging on the wall was covered in dust.
The blade left in its scabbard had rusted over.
The techniques I hadn't used were forgotten.
The body I was to train was left to grow soft.
I had lost the will to practice discipline.

I thought things would end without a single word said.
I pretended not to see violence inflicted by others.
I had given up, assuming things would never change.
I believed there was no way to oppose such a great power.
I sneered at hearts that tried to believe anyway.

I laughed, thinking them brainless fools.
Those were the thoughts I had taken refuge in.
I had given up, believing nothing was possible in the end.
I lamented the foolishness and ugliness of it all.
My life had lost all meaning.

I had lost sight of those who were precious to me.
I could not believe in their kindness.
I was unable to save them from the grief that tore at their hearts.
I had forgotten the courage it takes to protect the smallest of joys.
I believed my words would never reach you.

The shield fastened to the wall gathered dust.
The sword kept within its sheath rusted.
I forgot skills that I no longer use.
I left my trained body as it is.
I lost my judging heart.

I thought that this could end without me telling anyone.
I saw others’ violence, and pretended not to see.
I gave up since I couldn’t change it anyway.
I thought that I couldn’t go against great strength.
I laughed at the hearts that believed.

I laughed at them for being worthless.
That’s how I ran from everything.
I gave up, thinking that it was impossible.
Foolishness and ugliness brought me much lament.
I lost my life’s meaning.

I lost sight of my treasured person.
I could not keep believing in their gentleness.
I could not save them from heart-tearing sorrow.
I forgot the courage needed to protect mundane happiness.
Because I thought that these words will never reach them.
