May Tomorrow Be a Clear Day.Mao, watching Saya and Hagi talk and hold hands, asks Kai if Saya is her competition for his love. She sends him out shopping, then asks Saya to catch him because she has some embarrassing things on her list, then keeps Hagi from following by saying she needs his help around the house. At the subway station, Saya starts to faint, almost falling in front of the train but Kai catches her. Later, Saya promises Kai that she will always protect him and asks him to take better care of himself. Kai has a key of their father's bar made for Saya, so they can run it together. David leaves the hospital and returns to work. Saya and Hagi remember her making him promise to kill her, with his own hands, when everything is over. As he, Lewis, Julia, Joel, and Okamura discuss the situation, they realize the American government has Cinq Flèches deliberately creating chiropterans in America and abroad in order to create enemies that can only be defeated using the Corpse Corps. Julia explains to them that Diva's singing, when heard in person or a live process, it increases the effectiveness of the D-base (which causes people to turn to chiropterans) from 3% to 100%. Meanwhile, Nathan visits Solomon and takes him to see Diva and the babies, which Amshel "cut out of her stomach." Nathan tells him that now that the babies are born, he has no reason to fight his family anymore. To prove his commitment to Saya, Solomon attempts to kill Diva, but Diva easily defeats him and leaves him badly wounded. As Diva takes the babies inside, Nathan wonders if even a chevalier can survive such wounds.
