Prologue

Isadora Collins. A demon who has looked after Yui since she was born. Watching over her until they met forming a friendship, but soon Isadora reveals the truth about her being a demon and forever loyal to Yui. In doing so, she accompanies the Sacrificial Bride to the Sakamaki Mansion, where more secrets lay hidden for both females, as the six vampires take them in, though they favour Yui more than Isadora. However, even though Isadora is intelligent, she cannot piece together the obvious clues that lay before her about her past and more of the contract she has with this bride.
