The Pain I Felt( Neglected Son of Meliodas story)

From the moment Y/N was born, he had already started to receive less love than his 2 siblings. His older brother was already showing his demonic abilities from the age of 2 while his sister showed her goddess abilities from birth. Also, the fact that his father Meliodas had already lost some of his emotions did not help his situation. Meliodas was extremely proud of the other 2 siblings because of their extraordinary potential at such a young age but for Y/N he never batted an eye, neither did his mother Elizabeth. After many years of neglect and pain, his rage reaches its limit and reveals a power that would rival the Demon King himself.
