The Red Spirit

Ren and Zhou are on their way to school when Zhou smells something delicious. They follow the smell down a small alleyway and through a wall of glowing fog into the House of Heroes.
There they meet a strange man, Alba, who knows their names. He introduces them to his friend Taro, from the Land of Jura, who says he needs their help to save his people.
Can Ren and Zhou help Taro? What happens when they arrive in the Land of Jura? And what is the Red Spirit?
