A “gang” of four bank robbers pride themselves on robbing banks in the correct way. They have rationalized to themselves that they aren’t harming anyone, which is ridiculous, but makes a good stage for an interesting plot. This was a lot of fun to read and moves very fast.
This story centers around Tsukuda, who reluctantly takes over his father’s small engine business after failing as a rocket engine researcher. However, he keeps his dream alive pouring the company’s money into a rocket related side project and re-applying the results to small engines. When a large corporation needs Tsukuda’s technology to compete globally in the commercial rocket industry things get complicated.
