Chika's ibis finally explodes in the stalemate B-rank battle ROUND5 / night section. The Kakizaki Corps and Katori Corps, who have no way of shooting Chika, develop a linked strategy and attack the wire zone where they have been trained. The Kakizaki corps attacks the area where Yuma waits, and the Katori corps attacks the area where Osamu waits. Each looks like 3 to 1, but with the addition of Chika, who is in a position to aim for sniping in both areas, the situation is actually 3 to 2. In a situation that seems to be numerically disadvantageous, Tamaki's second new tactic shows its true value.
