'''Aosaidan''' (Youkai-go: '''青祭壇''', lit. pronounced ''ah-oh-sah-ee-dan'', lit. "Blue altar") is a small [[Youkai Nation]] town located in the Northern Zone.
Aosaidan was founded in E7-215, sometime during the month of Penultima, as part of the [[History of the Mazes#Era 7|Youkai Expansion Plan]], to answer the needs of an ever-increasing [[youkai]] population. Aosaidan transliterates to "Blue altar"; the origin behind the town's name is unknown, but it is believed to have a connection with the neighboring Angelic capital city, [[Cloud Ten]].
Like most towns controlled by the Youkai Nation, the local town population is mainly composed of [[youkai]], although there is a significant minority population of [[humans]] and [[Angelics|angelic creatures]] as well. It The local ammunition factory, opened in E7-217, is a small town the first 100% youkai-owned and youkai-operated factory of its kind, sourcing most of its raw materials from the [[Kazama]] mines. Headstamps of ammunition produced at the Aosaidan factory are typically marked with few notable features or attractionsthe letters '''AD'''. There is no official explanation for what these letters stand for, but the most commonly-accepted theory is that they are a shorthand for "'''A'''osaidan '''D'''anyaku" (青祭壇 だんやく), which translates to "Aosaidan Ammunition".
