It was a useless ability, right till the very end. That’s what Shion thought as he was dying. Among all the tr*sh, it was the tr*shiest that could only record.

Even when the Libra family was taking his life, his ability, ‘Notepad’, could only record.

But then, with his return, the amplification of the Notepad occurred. Not only recording and storing, but also recalling memories.

All the conditions were prepared.

“My future dream is to be a guardian knight of Libra.”

Now, Shion is about to record their downfall from the closest place to his enemies.

The hero who was killed by the demon king ended up reincarnated as the son of the one who killed him! Thus began the life of the hero who donned in the mask of the ideal demon prince to topple his own kingdom while doing his best to prevent anyone from discovering his identity―― But to do that and blend into the demon tribe society, he had to kill his former comrades. Nevertheless, to become stronger, to save humanity, he had to walk through all kinds of paths of carnage! This is the tale of the demon race’s fake prince destroying his own kingdom.

O Hero, Trample Those Who You Should Protect!

TN: Most part of the other character in the novel is depicted from a non-human perspective so expect something that is completely different from the common sense of human.
