It all started with a letter. A letter that brought them to a mansion. A mansion that then trapped them inside with a monster. A monster known as the EnderOni. Now 13 unlucky minecrafters are trapped inside the EnderOni's mansion, forced to solve puzzles and fight battles to even keep alive, let alone escape. But it doesn't stop there. One of those minecrafters already knows how it ends. He's seen it all before in the previous loop, and he'll see it all again in the next. Never once in any of the loops has he gotten close to freedom. But maybe that can change. Maybe, after learning from all his mistakes, he can finally outsmart the EnderOni.

He knows he has many fangirls but he was certain that it was the first time he had laid his eyes on her. This is definitely not the usual.
