The Ten Commandments vs. The Four Archangels「十戒 ｖｓ．四大天使 Jikkai vs. Yon Daitenshi」 is the 205th chapter of the manga, Nanatsu no Taizai.
The two newly arrived Archangels, Sariel and Tarmiel, begin their attack on the Demon Clan army. They quickly annihilate all the demons but the Ten Commandments with Omega Ark, and then proceed to fight the five greater demons, seemingly overpowering them.
Ludoshel leaves the Light of Grace to join the fight, leaving Nerobasta to guard the gate that connects Stigma HQ with their angelic reinforcements. Soon after, however, Gowther arrives, using his power to make Nerobasta think he is Ludoshel himself, and asking her to let him enter the gate.
