Under the gray sky, you can saw a figure standing on the field. It was a scarecrow.
Scarecrow in Japanese called "Kakashi"
We know what a scarecrow does. It's mannequin that stays on the field, scare away the birds and crows from eating the seeds. If the seeds were gone, nothing can be grow, and the field will become empty and boring.
...But what is a mannequin? It's just a heartless and emotionless figure. It cannot feel anything or express anything. It was just a tool, a robot, waiting for someone to control so it move into a different direction. Even so, its eyes always stare across the field and toward the horizon whenever the sun went up and down, as if it was looking for something far away. Something precious...and the scarecrow wait for it.
The scarecrow was there when the crop grows...and when it finally grew, the scarecrow was now and worn out due to the bird and crows trying to attack him. However, it stand strong under the nature. No matter it was bird, crow, sparrow, storm, wind, hurricane...it was there, watching the crops grow.
Now, let's talk about Hatake Kakashi.
His name means "Scarecrow on the field"
Wait...that sound familiar...
It does.
He was a mannequin without emotion who stayed on the battlefield. He protected the next generation, the little seeds, his students from danger. He once as a tool for the village, waiting for the Hokage to give him mission and keep him moving around, or else he would stay still and silent again, losing in this thoughts and looking toward the sky in guilt...waiting for a chance to redo everything. He lived in the past even when the days passed by. He watched his student grows as he aged. He was still young, however, his eyes and body weren't...They were cover with scars, his eyes filled with blood from his enemies that tried to touch his comrade and no more sparks of shining light was visible.
Even so, he would still be there...watching them grow...and he will continue to look across the field and watch over it until the end.
