S1·E46 Mysterious World's Maze

Tokine gets through the main entrance of Kokubouro, destroys Koshu, and continues her search for Yoshimori. As he is finding his way in the castle, Yoshimori sees Kaguro and stops only to contemplate about his current duties. He decides that his revenge will have to wait because his most important mission as of now is to locate and save Sen. While aimlessly searching the castle, he encounters the princess, who, unbeknownst to Yoshimori, gives him the map of the castle in his mind. After this encounter, the princess disappears and Yoshimori realizes that he, for some reason, knows his way in the castle now. He calls this his "natural intuition". Yoshimori saves Sen. Meanwhile, Heisuke found Byaku, who appears to be the "white" target that he was searching for to settle a score.
