So, the UN finally ran out of money and all the Jaegers were scrapped, and the pilots let go. Out of nowhere here comes Japan and the Anti-G forces, who proclaim "ah, leave it to us. We've had your problem for bloody decades, leave it to us."
They send three machines: the Gotengo, Mechagodzilla III, and MOGUERA, together with their relevant personnel(which means two pilots for Kiryu, with one in reserve) to Shanghai where they'll start ripping into Kaiju coming out of the portal as they come.
Can the Anti-Godzilla forces do a better job?
