"Distraction and Restriction" 

[This boy feels even stronger than Finley Walter back then...anyone knows his family background? Is he really not another mafia child or an assassin organization's little heir?] 

[To be able to show this kind of strength at such a young age. He's definitely talented. Super talented. Maybe he had never experienced a life-or-death situation and just learned quickly.] 

[It's normal for mafia's kids to kill people the moment they awaken their abilities to make them get used to killing and such. Maybe the boy is also trained like that.] 

[The mafia and other dark organizations are really cruel to their children. I heard that they didn't want children to be their weakness, which is why the children are all trained hard from a young age.] 

[Well, living as a mafia family member in a place full of territorial war and such is indeed dangerous.] 

[To be honest, I won't be surprised if this kid has already participated in small territorial battles.]
