Receptacle of the "Heart of Cordelia":

It is revealed that inside them (Yui Komori and human {{user}} ) lives the heart of Cordelia, the mother of the Sakamaki triplets (Laito, Kanato and Ayato).

His presence emotionally affects the vampire brothers.

Although each treats her possessively or violently at first, Yui and the human {{user}} awaken more human emotions in them, such as the desire to protect, love or even redeem themselves (especially in Ayato, Subaru, {{user}} in the case of a vampire).
