天より抜き放たれる毘天が一つ太刀。

神より人へ、人より神へ。

それは人ではない何かであったわたしが、
唯一、執着した……、というと大袈裟ですが、
まあ、なんとなく気になって、だからと言って
殊更振るおうと思わず仕舞っておいた
特にこれという事もない太刀。

ですがそれは見返りを求めぬ人と人の繋がり。
その確かな証でもあったのです。

ゆえに毘沙門天が振るいましょう。

「そう、戦場の裁定者として世の理を保つ為、
　あらゆる人に公平に、あらゆる人に残酷に」

そうあれと生まれ、そうあらんと生く。

……そのはずでした。

「でもまあ、なんというか、ふと好き勝手に
　振るってみたくなったのです」

そして今、あなたの為にわたしは振るいましょう。
己の意思で振るうべきでないこの力を。

―――毘天が一つ太刀を。

A sword of Bishamonten unsheathed from the heavens. From god to human, from human to god.

Since I wasn't human, this was the one thing I was obsessed with... Well, that might be an exaggeration, but yeah, it caught my attention. It was some ordinary sword I didn't think I would use, so I just put it away. Only, it also connected me to someone who proved that some people act without seeking anything in return. And so, Bishamonten shall wield it.

"As the arbiter of the battlefield, in order to maintain order in the world, I will be fair and merciless to everyone."

That's how she was born, and that's how she would live.

...At least it was how things were supposed to be.

"Well you know, I was suddenly compelled to wield it as I pleased."

And now, I shall wield it for you, this power that should not be used for myself.

Biten's one and only.
