識別クラス怪獣に襲われた東方師団エリア。鳴海とキコルは各個に撃破するも、保科の対戦相手は試作品・10号の完成品・11号。さらに保科が装着する識別怪獣兵器は、解放戦力が83％以上にならず苦戦を強いられ!?　
──想定を超えた、第十二巻!!!

The Eastern Division has been attacked by identified-class kaiju. Narumi and Kikoru have taken care of their targets, but Hoshina is still facing off against No. 12, the finished project that No. 10 served as the prototype for. Even worse, Numbers Weapon 10 won’t output more than 83 percent unleashed combat power, making this battle even more of a struggle for Hoshina!
