Run, Daihatsu Tanto! is a gag manga by Ashirogi Muto and their second serialized series. The series was often ranked 12 in Weekly Shonen Jump (although ranking 11 in one chapter). Ashirogi Muto later cancelled the series, concluding it early due to them being unable to surpass Eiji Nizuma with it.
It's about an elementary schooler, Daihatsu Tanto, the grandson of crazy inventor Daihatsu Meijin. Meijin "accidently" makes a new (and strange) machine in each chapter that his grandson uses, (usually for mischief) but nothing works well, and each invention is ultimately confiscated by Tanto's teacher, whom his grandfather is in love with.
After Run, Daihatsu Tanto! constantly ranks below the top ten Mashiro decides to conclude the manga despite Sasaki's disapproval, due its inability to compete with Eiji's Crow or Iwase's +Natural . However, Sasaki challenges Ashirogi Muto with their goal: they may continue writing for Jump, but only if they can beat Nizuma. Failure to do so would result in the permanent rejection of Ashirogi Muto from Weekly Shōnen Jump.
- The teacher resembles Yuriko Aoki, a mangaka who Takagi conversed with for references for the Tanto and who had a slight crush on him.
