| Stage |
Sumeragi Building 13 is part of the first round of boss missions from Gunvolt Chronicles: Luminous Avenger iX, alongside Store Ruins and Auto-fab Plant. Described as "the largest Sumeragi property in the world", Copen infiltrates this building in order to find information on the Butterfly Effect. Due to the intense security surrounding it, Jin proposes a plan to hop aboard a cargo train and sneak in that way.

Stage Composition
- The first half of the stage takes place on a moving train. While this is nothing new by Gunvolt standards, there is a midboss at the end of the train.
- The second half of the stage will feature odd jumping physics due to Stella's Gravity septima. Expect floaty jumps and the hazards associated with such.
