A human girl that sacrificed herself to end the Second Great War.
It is a misconception that she sacrificed her life, and ignorant stories of her “death” and “resurrection” are ever-present amongst the common folk. In truth, she sacrificed her life as a human, and the sensations that most take for granted. It is said that the young goddess lost the sense of taste, the ability to feel physical pain, the need for sleep, and the aging process halted.
While this may not seem like such a “sacrifice”, one must try to think of an immortal life, void of any physical sensation, or even the ability to sleep through the boring bits. Bleh.
