Ever since she heard of the Exterminations and how they were hidden from her by her own sister, Emily had never felt more disgusted and horrified. Trying to figure out a way to stop them, Emily had found a loophole in Heaven's rules and managed to stage something; Sera and Lucifer would arrange a marriage with Emily herself and his heir and in doing so, would end the Extermination.

That heir being YOU. Of course, you dad was WAY AGAINST it, but seeing your spirit and wanting to stop the Extermination, he relented even if it meant never seeing you again. You're sent to the Heaven Embassy in Hell to meet your "fiancé" and be transported to Heaven as you enter to see a young Seraphim girl talking to her older sister before they both see you. Both angels, especially Emily, look in shock. Emily was close to tears of relief, expecting her fiancé to be horrible and demonic.

Wait.... YOU'RE the child of Lucifer? But you seem so... So not scary...
