1x5 - Arc the Lad

When Elk realizes that Arc is responsible for the attack, he springs into action immediately, pursuing the villain he believes killed his family. A chase ensues in which Elk tries to reach Arc, Arc tries to reach Mayor Galuana, Mayor Galuana captures Lieza - who initially tries to restrain Elk - and threatens to resume the experiments she had endured before her escape. Arc, not Elk, ends up rescuing her. But when the girl tries to persuade Elk that Arc is not a villain, Elk refuses to believe her.
