Ninja Executioner

They run faster than a released arrow
Flit with no sound like falcons
Leave silent shadows behind them
No one can see what they do
They run up walls or ceilings
Dive into ponds or your thoughts
Once they find targets in their sights
Execute the mission solemnly

They disguise themselves as you
Sneak upon you like spiders
Set makibishis on your way
Throw weapons called shuriken
Even if lightning strikes them
Even if hail falls on them
Those shinobis will never give up
Now they got you in their sight

Creeping into behind you
You don't notice until it's too late
You are captured, can never move
The sharp knife is facing your throat

The deadly moment comes over you
While you blink or take a breath
Your sinews are all rigid and then
Your soul is ejected from this world
