PHI 1.618

In a dystopian future, a nation of bio-titans has been created and the female sex and procreation have become obsolete. As the Earth turns toxic, the bio-titans are eager to colonise the cosmos on board a colossal spaceship, taking with them only one female body kept barely alive as a reminder of the troubled past. But everything changes when the immortal calligrapher Krypton, tasked with creating an indestructible copy of the entire written heritage of his kin, sees a forbidden book turn into a feisty girl, Gargara.
