Lord Antonius is not a person who underestimates his enemies. Always choosing to fight cautiously, he prefers to eliminate his enemies from a secure distance and not take unnecessary risks.
Also, he respects the angelic race system and fears the wrath of the Gods. So he didn't think twice about attacking Envy and the people who defend her.
That fight seemed simple. Envy and Amelia are in the Earth Realm early stages, but the other women are just people from the Mortal Realm early and middle stages.
However, in those few seconds of battle, those supposedly simple women fought with a synchronism never before seen by Lord Antonius and his mates.
With strength and speed far superior to that of the Mortal Realm, those women managed to suppress those angels using their numbers, and with rare and incredible abilities, in addition to soul weapons, they actually seem to have more advantages than they, Sky Realm angels.
