In Episode 2, "Mononoke Chapter", the Musha Gundams attempt to solve the mystery of the apparition that haunts the town of Jaburo. Daishogun also has a treasure there...

Episode 3 is split into three parts (construably considered episodes 3–5), and is titled "Gundam Book of Genesis" (ガンダム創世記, Gundam Sōseiki). It revolves around a race of small, malleable Gundams and Zakus with designs based on haniwa (i.e. clay statues from Japan's Kofun period, ca. 300–538 CE). These creatures speak entirely in a fictitious language, and the story focuses on their small society's attempts to create new life.
