Twenty-year-old Kore's got her whole life ahead of her. 

All she has to do now is die. 

Finally of age for exposure to the pseudovirus, she's soon to be transformed and reborn as a Variant--one of those who can live freely outside of the carefully-controlled living habitat dome known as Gaia. Only then will she be able to follow through with her betrothal to King Aidoneus Hades--a man she's met just once but who makes her blood run hot. Only then may she attend the prestigious university for the newly transformed she's been daydreaming about for years.

But as her symptoms start to manifest and preparations for the wedding begin, tragedy strikes, threatening the life of Gaia dome itself.

Luckily, Kore's become a Variant the likes of which her world hasn't seen in hundreds of years...and the only one with the power to save Gaia and everyone living within it.

If she can survive her new life long enough to learn to control it, that is.
