Where evil lurks

Spring time
Carnival time.
Parades all over the place
Especially along the main artery
Tons of colorful costumes
From ladies of the court
To clowns
From regimental uniforms
To peasants and gnomes.
And one lone Samurai
Oddly out of place
And on a weird mission
As he took out his sabre
And started lashing left and right
People thought it was odd, strange and funny
Until he drew nearer and nearer
Started slashing, hitting, cutting and maiming.
Blood spewing out, people screaming, panic ensued,
Two falling dead before he was restrained.
Asked why he'd done this
He blamed the violent videos he watched endlessly
Since the early days of his youth.
Fed on violence and on a mission
To cleanse the world
And bring back its former
Purity.
