Thousands of years ago.
Io, the daughter of King Inachus, was persecuted by the goddess Hera because of Zeus.
Thousands of years later.
Argos and Io, the hundred-eyed giants who died tragically because of Io, were reborn again.
The little girl reincarnated in Argos, from stalking and being stalked, eventually became the reincarnation of Io, the guardian of Susan.
"It's just the next world."
For demigods and gods, life or death has no meaning.
