Last-Time Returner

[Synchronization rate has been set to 0%. Warning: Death is now permanent. The tutorial will begin.] A screen that looked like it came out of a game appeared before Ilyin Gray after being transported to the insides of a mysterious structure known as a Grand Ark. Just moments before, he watched as the world he once knew fall apart from the sudden invasion of otherworldly creatures before being whisked away to an unknown location. Fearing the worst for his homeworld of Arden, he progresses through the tutorial and escapes the structure, only to find that the ruined landscape he expected was nowhere in sight. Furthermore, the humans of Arden not only managed to recuperate, but over a century had already passed since then!?
[Welcome back, returner Ilyin.]
A message from the only divine watching over him confused him further.
\"I was reborn several times? But I don\'t remember a thing...\"
A story about a returner whose memories of his previous lives are lost, and his chances for do-overs are gone. As he adapts to the society that left him behind, Ilyin uncovers his past and the secrets of the world, all while overcoming dangerous threats along the way. Will his path end in greatness, or will he repeat the failures of his forgotten history?
