Located in the ocean southeast of the main setting of the manga, the Eastern Archipelago is made up of a number of islands.
According to Shuro, there are constant civil wars and battles between the inhabitants. Rin also mentions that those living in different areas of the Eastern Archipelago may not be able to understand each other's languages. In addition, very few people of the more long-lived races live there.
The cuisine of the Eastern Archipelago largely resembles traditional Japanese cuisine. Rice appears to be the base of most meals with dishes such as mirin-boshi-style fish, pickles and soup served alongside.
