Destroy thy Neighbor! A gate to another dimension has burst open, and invincible monsters called Neighbors invade Earth.

Having fought their way into the top B-Rank group, Tamakoma-2 gets to battle it out with the big boys for a chance to make A-Rank. Can this squad of rookies win against seasoned veterans who are nicknamed the "A-Rank Reserves"?
