Kaiju No. 8 manga volume 12 features story and art by Naoya Matsumoto.

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. 11, 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.
