Sachie-chan Guu and Jiya are introductions to the Galactic Patrol, a team of intergalactic crime stoppers inside the Dragonball universe. Sachie-chan Guu serves more as a heart warming little space romp, and foundational backstory to the Galactic Patrol. Without many plot elements, or mystery beyond the visual mark of the Galactic Patrol, this manga does not really do much to help the wider universe establish itself. However, what it does do is help green light further Galactic Patrol material, which is ultimately what occurred. With it's punchy art style, and clear story telling, Sachie-chan is an enjoyable read that leaves the reader wanting to learnmore about the Galactic Patrol.

Jiya is a more significant work than Sachie-chan, that tries harder to take itself more serious, and closer to something like DragonballZ. While written by Akira Toriyama, the art style heavily differs from Toriyama's usual content, which helps serve to shift the tone to something more akin to Go Nagai. Masakazu Katsura's influence is clearly felt in this work, as the tone differs heavily from something you would see in a Toriyama manga, and lacks many of the hallmarks that are found in almost every single Toriyama manga. This is not a bad thing, as the establishment of the Galactic Patrol, with different members and elements, having different personalities, serves itself to be written in different styles.
