In the world to which Kongwai and QQ Selezneva belong, the adventure of Ruca Milda is well known as a legend. It is believed, however, that the world to which Ruca belongs actually exists. Many have attempted to travel to this world, but no one ever came back. Kongwai and QQ later become the first to return from this world alive. Naturally, Kongwai had already known all about the journey he would take along with Ruca and the others, yet he neither reveals this to them nor interferes in the outcomes of the events that are sure to happen. His only aim in this journey is to save, or rather, to obtain two souls which turn out to be that of Thitose Cxarma and Hasta Ekstermi.
