What you want: The story before their adventure began.

When Haruka wakes with no memory and a mechanical heart, he knows only one thing: Minami, the quiet alchemist who brought him back. But the life Minami gave him is incomplete, fragile, and fading.

To save him, Minami hires two mercenaries to retrieve the Philosopher's Stone. What they find is a ruin that bites back, a mission that shatters, and a secret deeper than any of them expected.

This is a story about memory, sacrifice, and the desperate hope that love, like life, can be remade.
