[Explanation]
"Invention Sonta'', which began serialization in Kobunsha's "Shonen'' in 1961, is a science fiction adventure manga written by Riji Asano.
(After the serialization of this work ended, the author serialized a comic version of
"Light Speed ​​Esper'' in the same magazine.)
A boy who is an inventor... It was serialized for a long time due to the story line, in which people go on adventures in various places with various inventions, and sometimes exterminate bad people. It is not uncommon to see works in which the characters use mysterious items, but it was unusual at the time for the main character to create his own inventions. Wasn't it? This time, we will deliver the first complete version that includes all episodes, including read-throughs.
