Now staying in a hotel, Riku comes down with a fever.  Saya stays with him and Elizabeta talks with her about why she kills the Chiropterans.  After a while Saya finds out that Elizabeta isn't who she seems to be.  She and Haji fight her and Haji gets severely wounded.  That's when Elizabeta tells Saya a little about her past and invites her to visit "The Zoo".
