[Machine Translation] At last, Singh and Raina meet again as fate intended. Frederica and Crenna are horrified by the good vibe they create, and Leiden and his team are still struggling to get their heads around the situation. However, the brief respite was interrupted when the new unit, with Raina as operational commander, was given its first mission. The old subway terminal in the northern part of the 85th district of the Republic. Legion's base, built deep underground, awaits them with its mouth open. What they see is darkness. The darkness of Legion, of the Republic, and of his country's oppressors. Shin and Raina - "Ep. 4", the first time they fight together since they met! "A call from the depths of the earth tells them of a new ordeal."
