Tsurumi Island is a mysterious and abandoned island in Inazuma, covered in dense fog. This Island is a land that once housed two ancient civilizations, albeit at separate times, and is also an island filled with tragedy. At present, Tsurumi Islands esidents are enemies like rift wolves and hilichurls with no person in sight.
Much like Tsurumi Island, Enkanomiya has also been long since abandoned after the ancient civilization that lived there was killed. Also found in Inazuma Enkanomiya is far below Inazuma itself, so much so that it has no real sun, only an artificial sun made by its former people. It is a solemn place filled with little remains of the past and the past lives that once lived there.
