Truth

"Youngest reincarnation of the old universe, let me tell you the true origin of the Razkadan castle, and why we are here!"

Stepping forward, Nitran spoke the words which made Kyle avert his attention to the Reaper. 

He was looking at the Reaper hopefully and did not avoid his gaze. 

Kyle was highly curious about the history of the castle, the Undeads, and Beatrice, followed by the reason why he had been pulled towards the castle.

Seeing that Kyle had lost all his fear of the Undeads, they stared at him, unsure what to think about the young man.

He was still a mystery to them, and only Nitran, and apparently Beatrice knew more about him. 

The rest of them had no idea what exactly the words 'youngest reincarnation of the old universe' meant with reference to Kyle.

They clearly knew what a reincarnation was, but they weren't sure what the meaning of the Old Universe was.
