Tengu Onmyoudou

A skilled onmyouji named Yasunari is sent to look into a powerful figure's sudden shift in violent conduct and the possible spiritual forces involved. His only clue leads him into the mountains, where he encounters a young man named Ushiwakamaru. Yasunari assesses Ushiwakamaru and finds no danger in him. However, Ushiwakamaru misidentifies Yasunari as a tengu and requests sword instruction. The young man's true intentions remain unclear.
