A masterpiece of a “picture story” that approaches with an overwhelming sense of speed! Complete collection of two masterpieces of "picture stories" for upper grades that were serialized in "Tanashii 5th Grade" by Minoru Kume at the same time as "Super Catty"! The courageous activities of heroes who wear "rocket suits" that can fly faster than a meteor and become stronger than a tank! The bold composition similar to that of ``The Prince of the Sea'' and the densely drawn background are also impressive! (Commentary/Kume Kazu)
