After dying in a tragic accident, Yuna awakens at the foot of an impossibly tall tree the Tree of Rebirth. Around him stand thousands of versions of himself, each one shaped by a different life, a different choice, a different fate. Only one can climb to the top. Only one gets reborn.

Yuna has no memory of this place. But the others do. They've been waiting some for decades, some for centuries and they know something he doesn't: he's been here before.

In a race where your greatest rivals all wear your face, winning means everything. But the longer Yuna climbs, the more he starts to wonder what kind of person does he have to become to reach the top? And is the version of himself waiting at the bottom the one worth leaving behind?
