Sachie-chan Guu!! and Jiya are two stories of Toriyama with Katsura.
This has the stupid fun gags of Tori but can direct to has action and takes some serous.
I need to note in the two has very scenario of what the story takes about its very good the space, funny and some sci-fi. atmosphere.
Sachie-chan Guu!! has
Two charismatic characters with a good interactions
Jiya has
the charismatic characters but + the character Jiya is more interesting
two has simple script as DBZ but are the simple and more interesting characters that make very good manga i can describe this as the combination of two but authors series
DBZ simple script but charismatic + Zetman simple serious funny script
