The Holy Church force faced some predicament. On one hand, they did not face the bulk of the monster armies, allowing them to hold their own against the small forces after them. In another one, the said small forces compromised of elites, with all of them being A-rank monsters.
Arachne Guardian, Lamia Guardian, and Lamia Veteran made up the bulk of the small forces, with the leader being Lamia High Queen and Arachne High Queen.
Currently, the Holy Church forces faced their greatest, and likely last crisis, as the A-rank monsters easily pushed them back. Considering they have both quantity ( there are hundreds of them ) and quality ( all of them are A-rank monsters ), the say they are screwed is an understatement.
