Laira Lorelei

Laira is the current empress of the Seiren after her mother passed away. She entered into a cold sleep and has been sleeping for 800 years. [Spoiler] She awakens from her cold sleep and willingly joins Oceando, along with the Seirens and Dhampir, into an alliance with the Elchea Federation. [/Spoiler] [Spoiler] Due to her immense fertility as the Seiren Empress, she is able to reproduce even from the minute amount of soul essence found within a single lock of a male's hair. This is the case in which Sora and Laira now have a daughter despite no sexual intercourse and within a very fast gestation period. [/Spoiler] (Source: No Game No Life Wikia)
