Osamu successfully convinces Border HQ to allow Hyuse on to their squad, and now the moody neighbor from Aftokrator must make his way up through the C-Rank Wars to officially join them. Meanwhile, Tamakoma-2 gears up for another B-Rank Wars match against the analytical Oji Squad and the unconventional Ikoma Squad. How will Tamakoma-2 handle a squad that operates almost exactly like they do and another squad that doesn’t even seem to care that there’s a match going on?!
