曇天に笑う＜外伝＞ ～宿命、双頭の風魔～

The Fuuma clan has spent generations waiting for the serpent Orochi to return, and it raises its children to be the weapon that meets it. This second of the Laughing Under the Clouds side story films follows the twin brothers Shirasu and Ichiu as they climb to the head of that clan, and what the position costs each of them. It runs an hour and sits alongside the main series rather than continuing it.
