On a certain day, a certain thought came to Japan’s Sun Goddess. ——Aren’t there too many Japanese people being abducted to other worlds? It’s true that the large majority of Japanese are diligent and docile and soft-hearted, which makes them pretty much the best people to ask for favors. “But recently it’s just gotten way too out of hand…… Oh, I’ve got it! Whenever a Japanese person is summoned, I just have to summon an otherworlder!” And now, every time a Japanese person is summoned, princesses and elves and beastmen and whatnot are reverse-summoned. Under the acknowledgement of the government, they begin living in Japan. Today, too, Japan is at peace. And so begins this laidback isekai cultural exchange story♪

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.

My younger sister was not cute.

She was arrogant, taciturn and weird, but she knew how to please our parents.

She was two-faced and deceitful, but it seemed like she only treated me that way.

I cared for her, tried to please her as much as I can, but she still disliked me.

Until one day, I found out her secret, our relationship began to get a little bit weird…
