The Great Secret of Daimakai!

Synopsis

The Ganbar Team gathers at the Kirigakure home to train in ninjutsu. While they're at it, Gon spots a strange box in the inner garden. Inside is a scroll written in shinobi script — apparently it details the secrets of the Great Demon World. Just as the three boys and one dog hold their breath to read it, a pig-cat snatches the scroll away. They transform and recover it, but Yaminorius grabs it from them and turns it into the super demon beast Maichatter. Summoning Gekiryuger and Revolger, they face the beast — but can't destroy it before reading the contents. While they hold the beast at bay, Gon decodes the scroll. Chinatsu, who followed them, watches Gon and starts to wonder why he doesn't act like a normal dog.
