Hand Crank acquired.
「手回しレバー」を入手しました。
This is... a piece from a crank organ. At least, I think so...
There was one in instrument storage which, I think, was once a wangren that played music for itself...
Indeed. That fascination was how it became a wangren in the first place.
Then, a guilü came and stole this, its only means of playing, away.
今度はなに?レバー…手回しオルガンね。…アタシ思うんだけど…
楽器庫にある楽器ね、あれって昔は妄人だったんじゃないかって。自分でいろんな曲を演奏して…
そうよ、それで妄想を膨らませてたんだ。
鬼律どもが寄ってたかって演奏する術を奪い取ったんだよ。
