"If the chronometer is used to return time to its original course..." Suspicious that Ryoma may already have gotten ahold of the chronometer, Katsura confronts him and reveals the reason he is trying so hard to get the chronometer before Takasugi does. Despite knowing Katsura's motives, Ryoma gives him the slip, and with the chronometer indeed in his possession. Meanwhile, Takasugi learns from Seimei that he is the one who created the chronometer. In order to find out how the chronometer was created, Takasugi travels back to the past with Seimei's unusual powers.
