Symphony - The Origins [EN Version]

Giulia is a unique soul among humans, drawn into the Underworld at a young age. Often labeled simply as the half-sister of Percy Jackson, the celebrated Greek hero, she longs for recognition by her own name and aspires to forge a unique destiny for herself.
In the course of her life she will cross the path of a god destined to radically change her existence. From a common half-blood, she will become the latter's protégé, but only through reckless missions and the approval of that god's dead lovers will she be able to raise her name among the stars and shine, perhaps even more than her brother.

Everyone thinks I'm a depressed girl just because of my past, but hey! I've been living with it for years now and I'm fine》.
《No Giulia, you're not well...》.
I had sighed.

He had thrown the bottle, then picked it up again.
《And what do you plan to do?》.
《Try not to die and at the same time protect all my friends》."
