- Description from Novelupdates

I thought that when I was reborn, I would work hard to be strong—however, I only started to struggle when fate came.

Once, I was weak and powerless, but the ninja world imprisoned me bit by bit like a cage.

Hinata, Konoha, Ninja World, one day I will break the cage/break free from the shackles and act recklessly. And those who were about to die – will also be reborn.

Until leaving a sentence – tell them, this is the last time I will fight for this decaying village.

“What if you never come back?”

“Then they will never return.”

“It’s like the color of your eyes determines that we can never be together. Even at the last moment of my life, all I see is blood and night—and the only thing, the white of your eyes.”

“White—it’s so good!”

Is it really good – the world of white eyes is just pale without a trace of color.
