[Greek Mythology + Saint Seiya] It's Hard Being the Eldest Son

From the moment Hades became self-aware, he knew he was the eldest son.

The eldest son of a violent father and an unreliable mother, with five younger siblings.

...Wait, if he has an older sister, why is he still the eldest son?

[Voice from the heavens: Because you don't have an older brother ×]

He doesn't really mind, though. He won't have to worry about much anyway...

Like heck he won't! Weren't the gods supposed to be precocious, each of them smart and capable? Then why are his siblings so utterly exasperating?!

Forget it. You all do your own thing. Just leave me alone and let me have some peace.

...That's what he thought, but! Fate, what did I ever do to you? What grudge do you have against me?
