So the whole volume has been scanlated.

Spoiler for 4-6:

The Red Witch used her men as bait so she find where the Finn's snipers are.
Turns out Simo is not good with melee combat with the Red Witch and only survives due to an injured Aki.
By the volume's end, the Red Witch won her fight with Simo by shooting her but Simo won the battle by killing the General of the Invasion.
