A black-haired woman with no name or memory is taken by Nona to the Quindecim, where she is assigned to be Decim's assistant. Nona takes the woman backstage to observe the darts game between Machiko and Takashi, explaining the nature behind the games. After the game's conclusion, the woman expresses her thoughts, believing that Machiko only had a one time fling which she regretted and was lying about her baby's father in order to save Takashi's soul. This comes as a surprise to Decim, who is apologetic about being possibly mistaken in his judgement.
