Banished: I Activated the God of War System

Ethan Shaw, the only son of the Shaw family, is ostracized by everyone for his weak martial arts talent. Little do they know, this is all because the adopted son, Julian Shaw, practices a Demonic Art, siphoning away Ethan's Aura. After enduring constant humiliation, Ethan awakens the God of War System at a critical moment and leaves the Shaw family. Together with Noelle, who has always cared for him, he embarks on the path to becoming a God of War.
