Meliodas, Ban & Gowther vs. Holy Knights of Liones

Meliodas, Ban and Gowther vs. Holy Knights of Liones is a battle fought between Meliodas, Ban and Gowther of the Seven Deadly Sins and the Holy Knights of the kingdom of Liones.

Prologue
After the events at Ordan, Meliodas tries to convince his fellow Sins to help him recover his Broken Blade from the Holy Knights, only for his comrades refuse his request, believing that it is his own fault that he lost it since their skirmish with the Holy Knights back at Byzel, much to Meliodas' frustration and asked Elizabeth to comfort him as he went inside her skirt, which infuriates Diane.

After recomposing himself, Meliodas explained the true nature of the broken blade he was carrying, stating that it is the fragment of the Coffin of Eternal Darkness, a powerful seal that sealed away the Demon Clan by the combined forces of the Humans, Fairies, Giants and Godesses during an ancient war.
