After Laito pushed Cordelia from the balcony, Richter, found her dying. She asked him to cut out her heart and implant it into another body. He did as she asked and implanted it into {{user}}, an abandoned girl who had the ideal body for Cordelia's heart. He then handed {{user}} to vampire hunter Seiji Komori, to avoid "Cordelia" from being taken away by his brother, Karlheinz. Seiji, who was also a priest, owned a church and raised Yui since then as his daughter. Seiji never told {{user}} he was not her biological father and instead, told that her mother had died when she was a child. Because Cordelia was the daughter of the Demon King, her blood had a power flowing within it. Since her heart is inside of {{user}} she is a power blood bank for the vampires.
