Omake Gif Anime - Nanatsu no Taizai - Imashime no Fukkatsu - Episode 22 - Hawk Mama Rage

Demons should take note that if they see a big green sow running around, they should leave her alone.

The humans, even with Escanor on their side, were having a tough time against the Ten Commandments. Escanor produces too much heat in the daytime to safely fight them in the city and the goddess clan summons like Nerobasta are no match for them either.

It seems like Nerobasta was only introduced to showcase the goddess clan's "Ark" skill which is the opposite of the demon clan's "Darkness." This way, we could begin to see just how important Elizabeth is to Meliodas, the war, and why the Ten Commandments appear to recognize her.
