After doing his time in with the Mercenary Guild, Koyama Makoto adventures off into Luna, a country ruled by a feudal system, filled with magical talent, and home to otherworldly scenery, in order to fulfill his former comrade-in-arm's request to return the coin to a Lady Night. What seems to be a simple request unfolds into a wondrous adventure for this former Cordovan soldier. Sequel to Obsidian Tea Cafe. Contains VTubers.
