He is later revealed to be Mars' son and Sonia's younger brother, Eden defeats Koga in a battle of strength taking Aria back to Mars and is later shown heartbroken at Aria's death at the hands of his own father, eventually deciding to join forces with Koga and the others to stop his plans.

However, he also is very caring for his friends as he protects them from Europa's Terrible Slash, and his friendship with the other Saints increases during the series.
Aria is a girl who commands the element of Light. She was one of the two infants that Athena protected from Erebus during Seiya's fight with Mars, the other being Koga.

After being rescued by Koga, she travels with him and his friends to destroy the several ruins used by Mars to siphon the planet's Cosmo.

An energetic twelve-year-old young boy with no memories of his past. Originally a Steel Saint with no memories of his past, Subaru dreams of one day become as powerful as a god. He has little sense of duty towards Athena at first, determined to prove himself by defeating Koga, who became notorious following his triumph over Abzu, but eventually becomes more responsible and friendly during his travels with him. Among the Steel Saints, Subaru has the strongest Cosmo, and it is hinted that he might eventually obtain his own guardian constellation and become one of Athena's Saints. This is confirmed when he eventually learns to perform his own Cosmo-powered technique known as the Pleiades Impact and inherits the Equuleus Clothstone from a dying Celeris. The true nature of Subaru's powers are shrouded in mystery as he sometimes displays surges of overwhelming Cosmo when he is overtaken with fury and manages to restore and upgrade the Equuleus Cloth despite not having achieved the Seventh Sense, drawing the attention of Eden, who finds something familiar in his Cosmo. He is ultimately revealed to be Saturn, having turned himself into a human boy to bide his time.
