note: everything reads right to left
I am also still learning Japanese, so please bear with me.

This special 49 page storyarc appeared in Volume 21 of Shonen Jump (1996).  It gives quite a bit of backstory into how Ukon and Sakon became the investigative team they are as well as to why they travel the country.  It also gives a good explanation of  Bunraku and older pupptry styles.  This was especially difficult because three of the characters speak in Kansai-ben dialect, which is really hard to translate.  If you are new to Sakon, this is an ideal way to get started!

if you start at the beginning,
it continues all the way to the end.
