Nansei Ryoukaichou ~ Unknown Traveling East (南西 旅海場 〜 Unknown Traveling East lit. Traveling Ocean Place from the Southwest) is the 6th official project in Nansei.
The first track in the album was released on July 13th, 2013.
- Unknown Traveling East seems to be the project, which refreshed/updated Nansei the most. It added new stylesed covers, which looks differently than Touhou's and are used in every Nansei episode since than. The characters design/drawings looks less ZUN-ish. Also the way how characters are showed on music videos also changed.
- Accordinh to LENK64, this is the sequel of Toxic Difficulty.
- It is the first episode to be a sequel of a previous one, if Performance of Meadow Rain doesn't count.
