Leonard's Memory!!

When last time Shin used the memory cubes of Jake and the others? He got to see many things and mostly the useful experiences were highlighted. But now that he was using the memory cube of a regressor he wanted to extract all the memories he could.

He knew he may not like this experience. But he had to do that.

As Shin started absorbing Leonard's memory cube. He got to see the previous life of Leonard which he lived.

How he awakened as an F rank. He barely survived the monster attack. How the world started changing after that. How he was oppressed by others for being a low rank awakened.

All the events that are going to happen will impact the world. Finally Leonard's first murder. After that, he went on a killing spree. Even for a slight disagreement, he would kill the other person.
