Episode 200- Because I am a good person

According to Euria, these children were still strong and are getting stronger every day. These were children who had been training since they were young and were carefully selected by Kal.  For some time, Euria's bodyguard taught these children the Veria household swordsmanship as well as martial arts to make them even stronger. And combined with what they already knew and the strong physical abilities they had, they were becoming incredibly strong. 

Though they were still considered young teens, they were nevertheless mature for their own age. They have been through a lot and will not shy away from the responsibilities they have as Euria's mini helpers.
