Haruhisa Amago is an Area Warlord from Sengoku Basara 3. He didn't have a big role in the story except as one of Motonari Mouri's enemies. In a desert battle with him, Amago would conceal himself under the sand and travel along the ground like being a shark in the water. The player would have to search carefully and force him into his secret cave or go after him normally.
