Saber Marionette J

When Lime fled in horror at Tiegel's death, she encountered Soemon Obiichi, Otaru's swordmaster. At his query, Lime poured forth her confusion about hearts - they make her and her "sisters" happy, but they also cause so much pain...! What's the point of having a heart at all? Soemon offers to help her out of this misery, and by the time Otaru finds Lime, her heart - her otome kairo - is gone. Lime is stiff and unresponsive and her pupils have closed completely, but she's still alive. Otaru takes her home and puts her to bed. A crowd gathers in Otaru's house that before long is scouring Japones town for Lime's missing "heart", and Otaru joins them despite objections that he should stay with Lime. Soemon tries to console Otaru, saying that Lime is Lime, missing hardware or not. Otaru goes home and finds Lime waiting in the genkan (place to change shoes), up and around but still almost totally unresponsive to any stimulus.
