There is something strange about Niken. That's what Richard and the others thought. It was unusual to see that Niken would avoid Richard considering the girl always greeted and approached her dearest brother.
Well, Richard had no problem if Niken avoided him for no reason. Maybe his sister decided to punish him for his cold attitude to him in the past.
He realized he had no right to complain and accepted Niken's silent cold treatment of him.
However, what made him feel confused was that the girl had become super silent ever since she came back from… who knows what year the girl went. Niken didn't even respond to Kazuto or Lionel, her traveling companions for this year.
Was Niken upset that she was taken home without her permission? But wasn't that girl the one who asked him for help?
Richard remembered, the girl asked him for help in a muffled sob... or did he hear wrong?
