A Low Down Dirty Game!

Kururu develops a seemingly innocent board game which shrinks Natsumi and Fuyuki and places them in the middle of the action. Landing on any rewards and penalties on the squares turns them into reality, and while Fuyuki gets sidetrips to assorted wonders of the world, Natsumi winds up executing one impossible stunt after another. The final square is revealed to trigger the Keronian invasion, but this scheme falls apart as the square before it summons Angol Mois' father, the original Destroyer of Worlds!
Inspired by the sight of 556's attention-grabbing antics, Dororo asks him for help - and is fed with 556's vitriol and drive for life. Returning to the Keronian base, a pumped-up Dororo rallies his fellow soldiers, pushing them through all forms of training in order to master a new combined battle technique - but all his efforts to strengthen his own presence fall flat, as the other four promptly forget about him the moment they put their training to actual use.
