Tendokyo

Tendokyo is a sky island currently above East Blue. It has been moved to its current position after being successfully crossing the Red Line from the North Blue. A kingdom currently resides in this island named Tendokyo Kingdom. The kingdom is currently ruled by Tatewaki Heisei IV, the son of Tatewaki Heisei III which was killed during the siege of the Right Wing which led to Arleigh D. Shiraz's disappearance 13 years ago.

The island is the birthplace of Shiraz's son and the universe's main protagonist Jonathan Arleigh and soon, his pirate crew will use the island's name to become the Tendokyo Thirteen.
