赤子が生まれた。
その赤子は不思議な事に声も上げずにただその手を握りしめていた。
赤子の手には黒く光る勾玉一つ。

生まれてすぐに赤子の両親は死んだ。
流行り病で死んだ。
赤子は一族の縁者に引き取られた。
赤子の手には黒く光る勾玉一つ。

赤子が子供になる頃に縁者も死んだ。
戦で死んだ。一族は子供を遠ざけた。
集落のはずれに遠ざけた。
子供の手には黒く光る勾玉一つ。

子供が少女になる頃に一族も死んだ。
病で、嵐で、戦で、飢えで、
人が恐れる災い、
ありとあらゆる禍で皆死んだ。
少女の手には黒く光る勾玉一つ。

生まれなければ良かったと、呪いの声に育まれ、生まれなければ良かったと、少女は己を呪いつつ。呪い呪われ生き続ける。望まず望まれ巫女となる。
巫女の手には黒く光る勾玉一つ。

―――すべては黒き勾玉の、滅びの巫女の力ゆえ。

でもそんなのはきっと気のせい。生まれる事は罪ではない。そう教えてくれた人がいたのだから。そう信じてくれた人がいたのだから。

「ですから未来さん、私と一緒に証明して欲しいんで
　す。この力で人を、なんなら世界だって救えるんだっ
　て事を！」

―――黒い勾玉は、きっともう光らない。

A baby was born. For some reason, the baby never uttered a single cry, but she was gripping her fist tight. Inside her hand, there was a magatama as black as onyx.

Soon after, the baby's parents died of an epidemic. The baby was adopted by relatives in the clan. In her hand, there was a magatama as black as onyx.

When the baby grew into a child, her relatives died in a war. The clan tried to isolate the child from everyone. In her hand, there was a magatama as black as onyx.

When the child grew to be a young girl, the entire clan died from illness, natural disasters, war, and famine. Every type of terrifying calamity plagued the people and ultimately killed them. In her hand, there was a magatama as black as onyx.

The girl grew up hearing she should never have been born. She cursed herself for being born. But on she lived, being cursed by those around her and cursing them in turn. In the shrine maiden's hand was a magatama as black as onyx.

Everything stemmed from this magatama...the power of the shrine maiden of destruction. But that was probably just everyone’s imagination. There is no sin in being born. She only realized this when...there was someone who believed so.

“That’s why, Future, I want you to prove something with me. I want to prove that this power saves people...maybe even the world!”

...The magatama as black as onyx will likely never shine again.
