Ritsuka uses his true name, Loveless, as a password to open a file in Seimei's computer that was never accessible before. There he finds pictures of himself and Seimei and a letter telling him that he has left Ritsuka the Fighter, Soubi. Seimei and Soubi were a fighting duo like Breathless, Seimei being the Sacrifice and Soubi being the Fighter. Now that Seimei is dead, it has fallen upon Ritsuka to take his brother's place in the fighting duo and become the new sacrifice.
