In this 'Senshi Kijin (剪枝畸人),' '枝' means 'arms and legs' and also indicates 'fingers,' so the signature is Akinari's mocking the middle finger of right hand and index finger of the left hand, which became disabled when he was a child.
この「剪枝畸人」の「枝」は「肢」、さらには「指」に通じ、幼いときに秋成が、右手中指、左手人差し指が不具になったことを戯れにした署名である。
