He, with endless life and the ability to change into many forms, arrived to protect the people.

She who first saw this, Hayase, is the guardian to whom Fushi was bestowed by god.

But the existence of this miracle is still fragile, perilous...

Those who protect it will surely be chosen by the heavens.

TO TONARI

We successfully managed to secure a place to live, but there's no one to watch the kids.

But I believe. I believe we can all make it even without parents.

Have things calmed down on the island?

TO NAND

We still haven't finished our reconstruction work. The Immortal made it off the island, but I think I'll be here for 15 more years or so.

I think there are a lot more kind people on this island after the Nokker attack. And, fortunately, I'm still alive even though I'm the island leader. And some of the adults are even saying they'll protect me.

Another tournament to decide the leader apparently started up on its own, but everyone had other things to do, so there was no audience for it. I think everyone's noticed by now. What this island needs isn't murder, it's cooperation.

The people on the island come to me, wanting to hear about the Immortal. It seems like a new religion is on the verge of forming here. Like, Immortalism or something? Makes you laugh, right? And the guardians Hayase leads are fanning those flames. They even want my diary. And I know why.

If you stop receiving letters from me, just assume they killed me.

Trivia

 * In an interview with Oima Yoshitoki, Oima said that each volume cover depicts a character's dream. Because Tonari's dream was to leave the island, volume 6 shows Tonari on the same island she dreamt about in chapter 47.
