After a near-fatal mission, Robin is left dying. Then, after only a day, he's better. To the team's shock, he's even better than before, and seems to have received some shocking new powers.
Gaea is defeated and the world is saved, except for Percy. He wakes up in a different world not much different from his previous one, told that he'd been in a coma since he was told. Only he can choose what is real or not real.
The sequel to "Sister or Sin?" Robin grows, learning with his sister, whom he discovered for the second time. This summary is terrible.
