Tsuranuki joins the team, but it’s clear that he and Akita are not getting along. But there’s no time for an intervention. A deadly new Giant Monstrous Beast appears, and this one appears to be designed to target the weaknesses of the Shinkalions… and their drivers… directly with fearsome weaponry and deadly tactics. And worse than that, this one appears capable of regenerating when cut into pieces! Soon after, Hayato’s father receives orders that further complicate the situation.
