"Episode 9"

Yui experiences more chest pains and leaves the mansion in the middle of the night to seek answers and finds Shu in an abandoned church. At first, he is unhelpful but quickly becomes interested in obliging her request for answers by forcibly tasting her blood to verify that it has indeed changed somehow. Richter then appears and takes Yui to the secret room where 'Cordelia' awakens and everyone feels it especially Ayato who goes to find her, to end up finding Yui's rosary on her bed.
